Q: I have a Heidelberg Prosetter 74 CTP. It worked fine before we moved it. After moving it, the CTP gave me error 3061 in the slow scan unit and the motor holding the optic head started moving from the beginning of the axis to the end. Nevertheless, the motor makes a noise and keeps on moving in its place as if the motor lost its zero point. How can I make the head find the zero photo cell?
A: The X43 SOP may have slipped out while moving. It is connected to 2nd board from top in the card cage and is a round Din 8 connector. It is located on the left corner.

Q: I am using the Heidelberg Off-set printing machine for our newspaper. My blanket developed a crack and I’ve bought blanket fix but the blanket fix did not fix the crack, it rather dissolve into the cracks. Is there any way that I can fix it?
A: Sorry but blanket fix is only a quick repair for a small mash in the rubber. Once the rubber is damaged with a crack or hole the blanket can no longer be used.

Q: We have a Heidelberg DI 46 - 4 colour. On the drive side, the impression on the magenta cylinder is very low. All of the other units are working fine.
Can anyone help ?
A: If the print pressure is uneven it may require a mechanic to adjust the print pressure evenly from operator side to drive side.

Q: We have 102 CD 40" UV press. In the key gap area, the ink dried on the fountain liner is really bad.
We have previously used your metal liners, and currently, we are using plastic liners. As the press runs, the ink starts to run out of control due to this drying problem

Could you help us with this issue?

A: The drying may be due to drying initiators in the ink and fountain solution. It may also be caused by having the ink fountain liners in the fountain longer than recommended. UV ink fountain liners should be replaced between 40 and 60 hours of operation.
  Back to top
Q: On my press I’m getting little dots around the numbers. Could you please tell me what causes this?
A: The dots around the numbers may be caused by excessive ink, too much pressure between the rollers to the numbering heads or the numbering heads hitting blanket to hard.

Q: I have a Heidelberg QM46 Single colour and the pressure builds ok and allows the machine to start. When a print run is started, the machine cuts out after approximately 200-250 impressions and then pressure needs to build up again before it will allow continuation of the run.
Any Ideas on what could be leaking as there is no obvious signs of a leak and it is quite hard to track when it only happens while it is in production?
A: Activate SF 23 and go into production , if the press still loses pressure after only running 200-250 impressions I suspect that Y2 will need replaced.

Q: We are experiencing a drying problem on our Raptor Pro Plate Processor. The plates are not completely dry when they come out.
Could you please give an idea as to why this could be happening.
A: The reason that plates on the Raptor Pro 85 Silver processor are coming out wet can be caused by a number of things. Below are some things that can be checked by the operator:
1. The first thing to check is that the wipers in the finisher section are not wavy and making good contact with the plate.
2. The second thing to check are the rollers in the finisher section. Make sure that they are securely locked into place. If they are, then remove the cover for the dryer section and check to see if there is any chemical leakage into that section. It should be dry. That would also determine if the rollers are doing their job of removing most of the finisher before it enters the dryer section. If there is some moisture in that section, you can swap the finisher rollers with the pair in the rinse section that is the next set of rollers toward the front of the machine. They are identical.
3. The third thing to check while the cover is off of the dryer section is that the air guides are correctly positioned (locked into place) to evenly distribute the air.
4. You can also check while a plate is processing by feeling at the back where the plate comes out to make sure the blower motor is working. You should also feel that the air coming out is warm. If correctly working, the air temperature inside the dryer section should be around 122 degrees. If there is good airflow and it is cool, then the heater is most likely defective and will need to be replaced. If there is not airflow, the blower motor and/or starter capacitor can be defective.

Q: I have a QM DI 46-4 and it is jamming. It is able to pull paper without printing with no problems, but when printing, it draws 2 pages and the jam indicator comes on. I am hoping to get some help.
A: If sheets feed and deliver ok with no impression, but stick to blanket and drop sheets as you have indicated this is normally a result of insufficient gripper tension.
You may need to repair the impression cylinder grippers and the chain delivery grippers as the springs may be weak or the clamping fingers may be worn.

Q: On our QMDI 46-4 classic, we are getting small gaps between each of the laser diodes after imaging. On the printed sheet there will be a very thin white line (non-image) between each of the laser diodes. Is this corrected by going into the service screen under the DB Edit and choosing the "Set Screw Correction"? By increasing the number by 1 or 2 will this make the imaging head go a little further before stopping its imaging?

Is the "Set Screw Correction" also used if there are overlaps of the diodes?

Can a negative number be entered in the "Set Screw Correction" screen as well?
A: This correction compensates for any pitch error in the lead screw and ensures that each diode zone is exactly 20.8 mm wide and that the individual zones directly adjoin each other.

-If the positioning range is < 20.8 mm, there will be gaps between the zones; these are visible as stripes on the plate and in the printed image.

-If the positioning range is > 20.8 mm, the zones will overlap and there will be a dark stripe at the start of the next zone.

-If the difference is more than 3, the correction value must be adjusted so that the difference is max. 3.

Q: On my QM46-2, recently the auto feed on unit 2 won’t grip the rear edge of the plate. It’s the same on ejection of the plate. I have to hook the rear edge on manually. What has gone wrong?
A: The issue may be related to several things...
#1 the leaf spring on the plate guide rollers may need replaced
#2 air piston Y12 may not be firing or the stop bolt it hits may be broken
#3 the rear plate clamp may be worn and not opening consistently
#4 the plate guide rollers may not be tumbling over due to a bent wire on the plate guide.
#5 the B6 encoder may be out of time
#6 the circumferential adjuster may be too far from zero.

Q: I have a Heidelberg Printmaster QM-46 2 with perfing. Recently the perfing has been coming on too hard and we can’t seem to reduce it.
It is perfing ok on the sheet (still a bit heavy), but when the end of the sheet comes it seems to bounce on to hard, which then perfs and damages the cylinder jacket area, which was not even the part of the sheet that was getting perfed. Any ideas?
A: Please refer to the image shown below. If this does not help resolve your problem, please contact your local service department.

Q: I have a Heidelberg Speedmaster 72 1984 model CPC 101 model. Whenever I run 100 gsm stock 20 x 28 size, the gripper at the delivery leaves the sheet when the impression is on. If impression is off, paper passes smoothly. Please help me to solve this problem
A: From your description it sounds as if the tension on the grippers is not strong enough to overcome the additional drag put on the sheet when you are on impression. The cause may be related to poor adjustments or worn parts of the gripper cam followers, gripper pads, gripper springs, or loose chains. I would recommend contacting your local Heidelberg service agency for this repair as this is not a task for the operator.

Q: We have a 1990 MOVS 96mm imp. Alcolors. We are getting a bump/ghosting streak at 1˝" and at 10˝". It really shows up when we are printing light screens. It is in all units but seems to show mostly in the Cyan and Magenta units. All rollers are 2 years old except for new waterforms in the Cyan and Magenta units. We are using Hostmann-Steinberg ink & fountain solution and Presstek Anthem pro ctp plates.
We have been using these materials for some time now and these streaks have been slowly getting worse. I have tried many different roller settings but have had no luck.
A: What you are getting at 10˝" is most likely a bump streak with 96 million imp. This can be minimized by checking and resetting the bearer pressures. The 1˝" could be a print interruption streak if you are running a solid. If the streaks are visible at that measurement no matter the ink lay down, or even when running a dry solid, then it is also related to bump streaks.

Q: We have a digital print shop within which we can cover A3 plus with our digital machines up to +/- 2000 sheets. After that we are out on price. So, we want to get a litho machine so that we can get into the longer runs. We initially wanted a 4 color GTO, but there are none available. The local manufacturer has a MOVPH 89 model available for the same price as the GTO. However, they claim we should be trying to get a SM 52-4 + L to complement our set up. When you ask a press operator for advice they say go for the MO because of the size advantage, but the people who sell say SM 52. I am not sure what to do. The MO is affordable and the SM is expensive. Our runs are mostly short now but that will change with the installation of any of these machines. With the MO we will need additional power and a bigger guillotine and space will be tight. Please let me know what you think as the wrong buy could be detrimental.
A: Things to consider: SM 52 versus MOVPH
  1. Age of machine
  2. Footprint of machine
  3. Cost to operate machine
  4. Ease of operation
  5. Long-range outlook
The MO may be cheaper to buy but there is a reason for that: the press is old technology and cannot compete with current machines in set up time, quality, or production. From your current description of the work you do, it might be better to go with the SM 52 if you can afford it, as you would likely be able to keep it busy where the MO may sit idle. You mentioned the cutter and the added cost for that, so you would also want to consider prepress. The imagesetter and plates for the SM 52 would be additional factors when considering your profitability. It is sometimes better to start out profitable by being smaller and more conservative, and then grow into a larger format as your work load improves.

Q: I’m running a 6 color 72 Speedmaster and a few days ago, the yellow unit became stuck on impression. I’ve cleaned the sensor between the magenta and yellow unit. I also took the side cover off to check to see if the pin holding the ram in place had come adrift, but it hasn’t. What could be causing this problem?
A: Here are a couple of scenarios for your issue.
A. If CP-TRONIC, press issue could be related to:
*defective board
*solenoid always on
*mechanically stuck
B. If Relay press, issue could be related to:
*defective relay
*solenoid physically stuck
*mechanically stuck

If don’t have nsuccess resolving the issue I suggest you call your local Heidelberg service team to discuss the issue and determine if on-site service will be needed.

Q: We have a QM-46 2 color. The machine is on but the display is blank.
We have tried to turn the machine off to reset it and the display will come back on but as soon as we hit the print button, the machine stops and the display goes blank again.
A: The issue may be related to a bad connection on the ZTK board plug X7 or SVK board plug X6. You may want to try a replacement of these parts. If you replace the ends of these 2 cables and still have issues then the press may have a short in the cable tree.

Q: I am running a DI 46-4. I have been running it for 3 months (have been running big presses for 18 yrs.). The press is not in a climate-controlled environment. It can get up to 90+ degrees F in the press room.
I am having two major problems. I am getting toning lines in the Cyan and Magenta units. When I look at the blanket, I can see gear streaks that match up directly with the gears. I also checked the ink to plate timing. The 2nd and 4th units appear to be correct (2nd-6:00 and 4th-7:00), but the other units are out of time. Could this cause this to happen? Is there a way to tell if the chilling units are working? I am not sure if they have ever had the refrigeration unit looked at. The temp reads 21.5 degrees Celsius. Not sure where it should be. I am constantly fighting this problem. This is the first time I have run a waterless press. On most presses, I can change the charge timing and get the bump streak (toning) to move. Not sure how to time the DI to do that. Hope you can help.
A: In your current environment it will be difficult to make the DI perform properly. Please review the following data and try to get as close to it as possible.
  • Ideal Press Temperature: 68-77°F
  • Humidity 50 + 5%
  • On the DI, if temperatures are too high, you will start to notice tinting (toning). If the temperatures are too low, ink will not transfer through the rollers, which results in wide color swings. Also, if the temperature is too cold it causes the electronics in the console to sweat. We all know what happens when water and electronics are combined. The cooling system temp should be 23-24 degrees Celsius (73.5-75 degrees Fahrenheit).
  • It is best to leave the temperature on the cooling unit set from the factory. It is also important to have a room where the temperature does not get above 24 degrees Celsius (75 degrees Fahrenheit). If there are problems with the inks tinting, have your ink manufacturer correct the problem. Do not adjust the temperature. We have tested the DI with many different inks and have done nothing to the temperature in order to make them run in the press.
  • The roller temp will run around 26.5-30 degrees Celsius (80-85 degrees Fahrenheit); you will need an IR temperature gun to monitor this.
Filling the cooling unit. The cooling unit needs to be checked every week. The bar pressure should be between 3.5 and 4.5 bars in order to keep the press adequately cooled. The pressure gauge is located on the left side of the cooling unit if you are looking at the side where you add water. It is round and has two indicators: one for temperature, which is the one on top, and one for the pressure, which is on the bottom. The following are directions for filling the unit:
  1. Run water hose until all of the air is out. I use a cut-off at the end of the hose to do this.
  2. Turn off press. Connect hose to press.
  3. You will need several towels. Stick one end of the ½" diameter clear bleeder hose on the Drive side of the press in a 5 gallon bucket and open the shut-off. This hose is located behind the door where you install the 1st unit blanket washer. It will be on your left. At the top of the hose there is a shut-off flathead screw, a hole is drilled in the cover so you can access it.
  4. Open the valve to the cooling unit and let the water from the hose run in. Be careful not to let water pressure get over 2 bars when you do this or it will come out of the overflow blow-off valve. Water should be coming out of the bleeder hose.
  5. Go to the Operator side of the press and stick the bleeder hose on that side in another 5 gallon bucket. Now open the bleeder screw. Water should now be coming out of that side, along with a lot of air.
  6. Go back and look at your water pressure; it should have dropped since you have both bleeders open. Turn the pressure up, while keeping it under 2 bars.
  7. Let the water run until all of the air comes out of the hoses and only water is seen. Keep the water flowing continuously, have at least four 5-gallon buckets on hand so you can rotate them (or you may use a T-connector to connect both relief hoses to enough tubing that goes to a sink or drain hole.
  8. Shut off the Operator side first. Then go and turn your water pressure down some as it will start to climb with only one bleeder open.
  9. Shut off the Drive side bleeder. Turn off water to press when bar pressure gets to 2.75.
  10. Turn press on. Pressure should go to 4 or 4.5. The needle should not be moving. If the needle is moving there is air in the lines and you will have to start over. In a couple of days the pressure should come down to 3.5 or 4.
Roller Settings (See Pg. 122 Fig. 15 in the operator’s manual)
  1. Spread light color ink onto ink roller. Idle press to smooth. Stop press and remove rollers 6, 7, and 8 for settings 2nd form to oscillator. Set forms to oscillators before setting forms to plate. Turn adjusting screws counter clockwise for wider stripe on all settings. [Exception: item m. below roller 4 to oscillator B is clockwise for wider.]
    1. Yellow screw - 1st ink form roller to oscillator B 3.5 - 4 mm.
    2. Blue screw - 2nd form roller to oscillator A 3.5 - 4 mm.
    3. Red screw - 3rd form roller to oscillator A 3.5 - 4 mm.
    4. If roller 7 has fixing screw on operator side through roller shaft, follow steps e.- m. If roller 7 does not have fixing screw, follow steps i.- m.
    5. Install roller 7. Tighten screws (pin to operator side.)
    6. Check stripes with rollers engaged to plate between roller 7 and form rollers 1 and 2. Adjust so that the stripe between roller 7 and foam roller 1 is the same as the stripe between roller 7 and form roller 2. Stripes should be same width (fig. 17/1 p. 124 in operator’s manual).
  2. Turning clockwise makes stripe to form roller 2 wide and to form roller 1 narrow.
    1. Adjust roller 7 so that there is a 3.5 - 4 mm stripe between both form rollers 1 and 2. (fig. 17/2 p. 124 in operator’s manual). Turning clockwise makes both stripes narrow.
    2. Remove roller 7.
    3. Install rollers 6, 7 and 8. Stripes from rollers 6 to oscillator B and roller 8 to oscillator A are preset from factory.
    4. Violet screw - form roller 2 to plate 3 mm
    5. Orange screw - form roller 1 to plate 3 mm
    6. Silver screw - form roller 3 to plate 2.5 mm
    7. Roller 4 to oscillators B and C 3.5 - 4 mm
  3. Replacing roller bearings
    1. Remove roller from press. Use bearing puller to remove bearing by clamping claws of puller around bearing and tightening threaded shaft of puller to the shaft of roller.
    2. Attach roller bearing to roller shaft by using angle piece tool. Place bearing against roller shaft and insert into angle piece so that bearing is against base of angle piece.
    3. Tap with wooden or rubber mallet on the base of the angle piece to press on bearing.
Oscillation timing is also important and should be corrected when it is out of position.

Q: I am having a problem with my QMDI 46. The RDI control panel does not light up once the press is turned on; none of the buttons on the control panel will function. The prompt on the screen reads "Connection Error, Must Reboot" and the operator cannot use the panel.
A: For QMDI Classic and QMDI Plus:
Turn off the press, lock it out, and then check the fuse on the SVK board. Next, check the yellow and red plug connectors on the SVK and ZTK boards; pay special attention to plugs X6 & X7 on the SVK board and plug X7 on the ZTK board.
For QMDI Pro:
Turn off the press, lock it out, and then check the fuses on the GSM board. Next check the plug connectors on the GSM, NTM1, NTM2, NTM3, UFK, & ZTK boards.
If none of the above resolve the issue, the machine may have a defective board or a short in the cable tree.

Q: We are looking to set up an offset printing shop and would like to buy four-color Heidelberg machine, could you explain the differences between the 1 MOV, MOVP, MOVP-S and MOVP-H? Also, would buying a 19"x25" machine or a 24"x36" machine be more beneficial?
A: MOV 4 colors
MOVP 4 colors straight or 2 colors over 2 colors in perfect
MOVP-S 4 colors straight or 2 colors over 2 colors in perfect. "S" means stream feeder
MOVP-H 4 colors straight or 2 colors over 2 colors in perfect. "H" means high pile delivery
The sheet size of the press will depend on your printing needs. You should plan to utilize your machine to its maximum potential to be most profitable. Just like purchasing the correct vehicle to deliver your equipment, make sure the press fits your needs.

Q: I have been having a problem starting my GTO 52. The warning lamp on the second unit is flashing, indicating there is an issue on the circuit. I have checked all the guard switches and they are fine. I’ve got the problem down to switch s75 but I can’t locate it.
A: The switch you are looking for should be on the drive side for the hand crank.

Q: I am running a 1996 QM 46-2. In special function diagnostic mode (sf 56); the press displays Error 1 (11-05) and Error 2 (15-05). What do these error codes mean and how do I resolve them?
A: Error code 11-05 means pressure switch S24 sensed that the pneumatic air pressure dropped to 6 BAR, which is too low for the press to operate safely. When pressure is too low, S24 will lock out the press until the air pressure reaches 8 BAR, where it will release the press to run. If the pneumatic air pump is running and the air pressure in the tank has is below 8 BAR, you may have a defective pump or an air leak.
If the pneumatic air pump is not running and the air pressure in the tank has dropped below 6.5 BAR, check the HVK board fuses F4 & F9 and breaker F3. If these components are ok and the pneumatic air pump does not run, I recommend onsite service from your local Heidelberg Tech due to safety and warranty issues on electrical parts. The press may need the HVK board, S27& S24, Y25, or the pneumatic air pump serviced.
Error code 15-05 means the main drive motor ran too fast; this could be related to drive belts, MRK board, TRM2 module, or the main drive motor. For this issue, I would again recommend onsite service from your local Heidelberg Technician due to safety and warranty issues on the electrical parts.

Q: I am running a 2005 PM46-2 and noticed some scoring on the ink fountain roller and ink fountain blades.
Are there any maintenance procedures that can be used to minimize scoring?
A: Here are a few things that can be done to help slow scoring:
- After removing ink from the fountain for cleaning, open all the ink zones before lowering the blade.
- When raising the blade into run position, make sure all the ink zones are in the open position.
- Never turn the ink fountain roller with the blade in the run position unless you have ink or roller lube in the fountain.
- To check the ink zones, fill the ink fountain with process blue ink and then gradually close all of the ink zones, starting at the center and working your way to the outside as the fountain roller is turned manually. When all the ink zones are closed, you should have a thin, even film of ink on the fountain roller. If you can see the bare roller, the zones are set too tight and should be adjusted to ensure that the roller and blade are lubricated properly.

Q: I use InDesign on an iMac to lay out print jobs for our Heidelberg DI. I lay out my artwork within the proper margins, but once it is sent to the DI RIP, the artwork is no longer centered. When the job prints, it is either too far from the gripper or to close to the gripper.
A: Here are a few things to check when printing to the DI press.
  1. What is your paper size? Take time to measure your paper and make sure you have the size correct.
  2. When building your document, build it to your paper size. This is why you need to measure your paper and ensure it is correct. For instance, the box that your paper comes in may say 18 inches but if you measure it could be 17.875 or 17.75 inches.
  3. When building your document, work from the center of the document outward.
  4. Once the document is complete, select all elements on the page and shift everything to the left 10mm. Now, go change the size of your document, adding 10mm to the right side only. Be careful here, some applications may add the 10mm to the left of the document when changing its size (Quark does this).
  5. There are 3 different RIPs that drive the DI press and they all will have minor differences on how the job is centered.
  6. Maximum sheet size is 18.11 x 13.375 inches
  7. Maximum image area is 17.72 x 12.99 inches.

Q: Is there a setting for my press that will allow me to run sheets without the impression cylinders engaging?
A: SF 23 Production without printing +on/-off
This setting will allow you to start and stop production using the green key as if you were printing a job, but everything above the blanket cylinder will stay in the off position. The blanket cylinder and impression cylinders will go on impression so that you can score, perforate, slit, number, dust the sheets off, or compress envelopes before printing them.
To use SF 23, the press must think it has a plate on at least one unit and a number must be entered into the counter. Also, be sure to put roller lube on inking rollers and dampening rollers to prevent damage.

Q: I have a QM 46-2. We are having an issue with the image disappearing on the front unit.
Recently, we ran 6000 impressions in black on the front unit with no problem. We cleaned up the press to run another job with a different ink in the front unit and it washed out. We can take the same ink and plate from the front and switch to the back unit and it will print fine.
It seems that running any other color but black in the front unit causes it to wash out. We have reset all rollers and have great stripes.
My pressman and I are stumped.
A: Without knowing the condition of the rollers or the mechanical parts of the press, it is difficult to offer a precise diagnosis of your issue.
From your description, it sounds like the inking and dampening roller trains on printing unit one are either contaminated or have an issue with the roller hangers. After a normal press wash-up, try performing a thorough cleaning of the rollers using non-petrol based cleaner, followed by water to rinse out any residue.
If this does not resolve the issue, you may wish to try a different set of rollers or schedule a service call.

Q: We noticed recently on our GTOZ-52, when a double sheet is pulled from the feeder, the press will shut down normally but will not stop the sheet from feeding through the press as it did before. Any ideas on what could be out of sync that could be causing this?
A: The problem described is normally a problem with the stop lever assembly shown in the diagram below.
The 60Y51 solenoid could be defective. Stop plate number 6 may also be loose or missing. In either case, a Heidelberg technician should inspect this to prevent any possible damage to your machine from a bad or misaligned sheet entering the press.

Q: I run a Quickmaster press that has been converted with UV rollers. The clips on the backhead guard (positioned below the water tray) keep breaking. Could this be caused by UV ink or washup weakening the plastic clips?
A: The QM 46 is not designed for UV application.
Even though you have converted to UV rollers, other parts of the machine are not designed for UV application and may fail when used in this manner.

Q: I am having registration problems on a MOVP 4 Col. I am experiencing some spread in the tail edge, which seems to be happening between Units two and three. I have double checked the bearer and blanket settings and everything looks fine. The MOVP has solid impression cylinders on units one and two and metal impression jackets on units three and four. The machine is not used for perfecting and the registration issue happens on a variety of different stocks. Is this a packing issue with the impression cylinders?
A: If the plate and blankets are packed to the correct specification, you should not have any registration problems. If they are, however, over-packed and the paper grain is running long, then registration will likely be an issue.
The reversing cylinder also plays a big part on sheet register at the tail edge of the paper. If there is excessive wear in this area, you could see registration suffer. You should also check the cam followers and Pincer gripper bar for wear.

Q: I am having a problem with my SM 74 two-color press. After finishing the set-up process, the press runs properly at first; but whenever we stop the machine (change the plates, feed new paper...) and then run again, we experience a deflecting error in the circumferential direction.
After running around 20 sheets, the error will disappear. However, if we stop the press and start running again, the error re-occurs and disappears again after 20 sheets.
A: Based on the information provided, you may have an ink tack issue or tacky blanket causing the registration to change circumferentially. If this registration error is occurring on both units, check plate and blanket packing in both units and make sure that they are correct. Once you know the packing is correct, you can reduce the ink tack and see if doing so has any effect.
Also, check the gripper bar cam followers for wear. If you have a weak gripper system, the paper will pull out under impression and change sheet register.

Q: I run a press with both ink train and ink fountain roller chiller controls. What are the ideal temperature settings for the ink train and ink fountain roller chillers? I notice problems when setting the temperature below 75 degrees - which is our average ambient pressroom temperature.
A: Generally, the ink temperature in the ink train is between 75 and 80 degrees Fahrenheit. The ink fountain temperature control is usually chilled with the inking unit (same cycle). Some machines have a valve in the circuit, and it is common to have it cut to about 50% flow. XL 105 machines have a separate ink fountain temperature control (usually 80-85 degree set point).

Q: Six years ago I purchased new a Printmaster 2 color with an Airtech sprayer. It worked fine until just recently. There is a pulsing of air in the plastic powder bottle... and air coming out of the spray nozzles, but, no powder. Without taking this apart, I used compressed air to blow out the passages. What am I doing wrong?
A: The information for preventive maintenance on your powder unit includes:
  1. Do not force the concentration knob past the normal stopping point
  2. Never use damp ’clumpy’ or coated powder in your system
  3. If the powder becomes contaminated, discard and wipe the inside of the powder jar with a clean dry cloth
  4. Periodically, clean the intake filter on the air compressor by removing it from the compressor intake outlet and blowing compressed air through the threaded fitting.
  5. Do not allow lubricants/solvents to drip down onto the control box or the spray bar.
These are the instructions for your powder unit, should it become clogged:
  1. Disconnect the black powder tube to the spray bar & blow pressurized air through the nozzle (40 psi max dry air)
  2. Carefully remove the "I-Tube" from the manifold of the powder jar assembly. Clear the tube by applying air pressure at tube hole. Clear the manifold by applying air pressure at the "I-Tube" orifice while the tube is removed.

Q: We are using a Heidelberg SM-74-2 color offset. When we run the machine, after about 3 minutes, the feeder automatically cuts out and the machine slows down. There is no error showing on the console. Again in the same condition if we switch on the feeder, it does not turn on, so we need to turn the mains off and re-run the machine, where after 3 minutes, the process happens again. What could be causing this?
A: This seems to be a possible electrical issue. If this press has a perfector, you might check and see if the drop sheet sensor is dirty and try cleaning it. If this does not resolve the issue, however, then you might consider calling in a technician for repair.

Q: We had a Heidelberg repairman remove the spray powder unit from a new QM 46 about 5 years ago and put it on our older QM 46. We have now scrapped the old press and attempted to put the unit back on the original press. However, the compressor for the unit does not turn on. Everything worked fine a few days ago and the installation was simple, what could be going wrong?
A: I’m not sure which model spray powder unit you have, and since there were several units sold for the QM46 I will need more specific information on the type of unit you are working with. However, this issue may be related to shorts in wires, a defective HVK board on your press, a defective pump, a blown fuse on the powder unit, or a defective power switch on the powder unit.
If you can find the model # on the powder unit or send pictures of the unit I may be able to find a wiring diagram for it. Email model number and/or pictures to

Q: I have a GTO 52 from around 1990 and I have 1 single color that will only run at a specific speed. It is running at 3500 impressions per hour and will not speed up or slow down. Any thoughts?
A: The GTO 52-1 from that time frame uses variable pitch pulleys that are hand adjustable at the feeder. If you adjust the dial for the speed and you have no change, you will most likely need a new drive belt. Other possibilities are the adjusting mechanism is not working correctly or the pulleys themselves are defective. In either case a Heidelberg USA tech can diagnose and repair this very quickly with an onsite visit.

Q: I have a PM46 that is 4 years old and I’m getting sheet gripper nicks every third sheet, mainly on text weight stock. The sheet advance is set to "0." I’ve identified the offending gripper bar as the marks are across the entire sheet edge. Do you have any suggestions as to how I can fix this? I also need to clean out envelopes that have fallen inside the press.
A: Have you adjusted the shims between the gripper bar and the chain? If so, and that did not help the chain delivery, the gripper bar may need to be set with the h gauge by a technician to ensure that it is opening and closing at the correct time. In order to clean out the area between the feeder and the delivery, you can access it by removing the DS cover and then remove the transformer labeled ’T2’.

Q: When running on the QMDI, the paper stopped after going through the sensor. If the sensor is removed, the paper can run. The error code we received is 11-08.
A: Provided that the operator knows how to properly set the double sheet detector and properly set the feeder for different stocks of paper, then there are two other things to check:
1. The upper eye may not be in alignment with the lower eye. The spring that holds the upper eye in place is sometimes bent from frequent removal and no longer holds the eye in the correct position. Also, it could be that the guide plate that the upper eye is affixed to is loose and moving during press operation.
2. The upper eye itself is dirty, scratched or cracked. This cannot be remedied without the complete replacement of the component.

Q: I Have a Quickmaster 46-2. When I speed up the press to around 8000 spm, the press shuts down. This is happening both when I’m feeding sheets of paper through and not feeding sheets.
A: This issue sounds like it may be related to a loose delivery chain or a safety switch on a guard vibrating open.
  Back to top
Q: The gauge on my press reads a little into the red after reloading the compressed air tank. I can’t find any leaks. Would I be able to increase the pressure myself?
A: The FESTO air control unit is preset and it is not recommended that it be adjusted by the operator. The S27 on the tank is responsible for turning the pump on and off and the S24 on the tank is responsible for locking out the press and releasing the press. It is recommended that neither be adjusted by the operator.
In order to check the operation of S24 and S27, an accurate manometer will need to be inserted between the air tank and the FESTO unit to make sure they are switching on and off correctly. In order to check the operation of the FESTO unit, insert an accurate manometer between the FESTO unit and the air distribution manifold to make sure it is operating correctly. Estimated labor for a tech to do this is 2 hours.

Q: I have a Speedmaster SM-74 with a CPC-104. We are unable to set the ink fountain roller for printing unit 1 because the pictogram for the ink fountain roller is missing. Selecting the first unit gives a blank where the roller pictogram is supposed to be, and even the +/- pictogram does not appear when you select this unit and the roller motor does not respond to the +/- button. We are unable to control the roller and it is spinning too fast. The pictogram was there a few days back and I am unable to figure out what swallowed it. My machine’s serial number is 623305.
A: Check the connection of the ink fountain motor (make sure the power is off). If this does not take care of the problem, then the motor for the ink fountain roller might need to be replaced.
  Back to top
Q: I have a Heidelberg Printmaster QM46-2. My problem: The impression cylinder does not engage until 4 or 5 sheets have gone through the press? Could you tell me how to fix this?
A: This issue could be related to the B4 sensor, the Y2 pneumatic cylinder, the Y16 solenoid/latch assembly, the three two-way valves, or the cam follower that operates it.
Activate SF23 and observe how quickly you can start and stop feeding sheets with the production key. If it is not responding instantly, then you should investigate: (1st) The Y16 solenoid/latch assembly, (2nd) the three two way valve, (3rd) the cam follower that operates it. If the response is instant then investigate (1st) The B4 sensor, (2nd) Y2 pneumatic cylinder as the B4 sensor may need to be replaced if it is not counting each sheet or the Y2 pneumatic cylinder may need to be replaced if it is not firing each time a sheet is counted.

Q: I’m trying to buy a 2001 Heidelberg QMDI PLUS 46 DI, but I had some questions. What is the maximum print run that I can do with ONE set of plates? How many 11x17 jobs can I print with a laser that burns the image before it needs to be changed? How often do I have to change the laser that burns the image of every unit? Do I need special ink, or is standard press ink okay? Lastly, where can I find consumables supplies?
A: 1. The plates typically last for 40,000 impressions on the first pass and roughly half of that on a second pass due to the powder on the paper wearing the plates.
2. You can image 36 plates before you have to changes rolls (36 plates/roll).
3. The imaging diodes typically last 3 to 5 years. There are 16 diodes per unit.
4. You can run any waterless ink on the machine. All the major manufacturers make the ink.
5. Heidelberg sells all of the consumables to operate the QMDI.

Q: I think we have a calcium problem on our SM 52 with rollers that are only a few months old. When using calcium cleaner, a white liquid pours out of the rollers. We have repeated the cleaning process up to twelve times but the white liquid keeps coming out. We use botcher EK Calcium remover washed off with warm water.
A: Many times the mixture between solvent and water and/or any other chemical mixed together can result in a white liquid visible in the wash-up tray. If you are experiencing significant calcium build up in the rollers that causes a print problem, it could be that the rollers have to be de-installed and then hand-cleaned before re-installation.

Q: We have a Printmaster QM 46 with perforating capabilities. Why would the perf start out wrinkling the paper then straighten out? The perf starts about 1/4" onto the paper but continues past the end of the sheet. The perf wheel unit is clean, free of burrs, and has a new perf wheel and bearing. The metal jacket has recently been changed but has a groove where the perf wheel hits. Can the time the perf impression turns on be changed? Could there be a bounce problem with the perf shaft?
A: If you are not printing or you are using SF23 when you are perforating, that is the first thing you need to change. To do this:
  1. Zero out the circumferential adjustment
  2. Make sure the jacket is installed properly
You can order the operators manual part # 00.999.1612 from Heidelberg parts department.

Q: I have a QM 46-2 and the side guides will not move in or out. How can I fix this?
A: First turn off and lock out the press. Then remove guards on both sides of the press to expose the gears and sprockets, and then move the side guides.
Check for any loose or broken chains, sprockets, and/or bevel gears. If no parts are broken, mark chains and sprocket positions so you know how to retime them when you reinstall.
Remove the chains on both sides and try turning each spindle until you find the one that is bound, after locating the bind and freeing it up you will then need to reinstall the chains making sure that the feeder and delivery guides are in alignment.

Q: What is error code 1 11-01 on a QMDI 46-4 classic?
A: Emergency stop on feeder control panel, 11S2NA actuated.

Q: When running my Quickmaster 46-2 at high speeds the press will stop. Special Function 56 will display error 15-07. What is this error? This issue occurs when feeding sheets and also when not feeding sheets. When increasing speed, the press will level off around 7,500 iph. The issue occurs when I try to increase the speed beyond 7,500 iph and after a few seconds it will stop. Along with SF56 error 15-07 I have one time received error 15-08
A: 15-07 - Time-out during acceleration to set point value. If the issue only occurs at high speeds, it could be related to the sheet override sensor or a safety interlock on the guards.
The SF 56 Error 15-08 means incorrect speed behavior during braking. The sheet over ride sensor could be activated by the gripper bars. The sensor is labeled S21, operator side on delivery end. If a guard interlock was only momentarily activated while the press was running it would not show up on S56. When this issue occurs, go to SF61 and check for main motor error codes.

Q: I have a problem with my spray powder unit on my GTO 46. It sprays powder when the handle is in the run position. It should only spray in the impression position - correct?
Also, I cannot adjust the amount of spray with the knurled screw, is there anything I can do to fix this?
A: It is possible that the switch for the sprayer is not set correctly. You may have to remove the sprayer, disassemble, and then clean all ports. Also, make sure that the knurled screw adjustment is not slipping on the pin - in that case you would have to adjust the pin.

Q: We have a Heidelberg GTO 52 perfector and the counter does not work all the time. We replaced the counter but it still doesn’t work.
Where is the switch that does the counting, I can’t find it in the prints?
A: Reach into the pile area where you would load the paper. You will see the switch near the operator side and mounted onto the bracket. Loosen the switch (not the bracket) and push the switch closer to the cam. It is likely that the switch could be defective. Be advised this switch will affect "impression on" so an attempt to adjust can cause you to lose some production.

Q: I have a question about my DI 46 - loading new plate motor is not taking plate in. I removed the small motor that runs cogs, tightened the screw - and now it turns ok. But, I found a plastic lever inside the case and I’m not sure where it goes.
A: The plastic lever described may be a part broken off of the nylon spacer that the motor/magnetic clutch rests against. The nylon spacer that the motor is attached to had a tab that rested in a notch of the motor case to position the wire going to the magnetic clutch.

Q: We have a Heidelberg 72SP. We switched to CtP 2 years ago and the 2 small round holes that the pressman used to line up the plates to the cylinder went away. We were told that no plate setter has those holes and everyone else is doing without them. Mechanic was here last week and mentioned that stops on the clamps may be off. My question is, are those holes that were being punched and lined up with targets on the cylinder under the plate, to be used for mounting every plate, or are they there mainly for relining the clamps back up to the cylinder and setting the stops on the clamps to the right place?
We seem to have problems with cocked plates and out of register plates.
A: The missing holes that you are referencing sounded like the holes used for pining the masking sheet to the plate during the plate burn process and if that is the case the CtP process would not require them.
Reference the PLATE CLAMP to determine which clamping system you are using and then compare the instructions for that clamping system to your current method of plate mounting.

Q: Can you tell us what these two codes mean that are showing on our Printmaster QM46? Error 11-05 and 01-03.
A: Error 11-05 = Pneumatic pressure control device S24 (the press thinks the air pressure in the air tank is too low to safely operate) and Error 01-03 = Printing unit guard on O.S.S6. (the press thinks the door is open making it unsafe to operate).

Q: I have a QM Printmaster and I want to find a listing of code for the press, ex: s-19 or s-01.
A: If you have a wrench symbol or a guard open symbol that you can’t clear by rebooting the press, please call Heidelberg services and a technician will ask you for the codes in SF56 to help resolve the issue.

Q: We have a Printmaster QM 46-2 and the compressor won’t turn off. Any ideas on what the problem could be?
A: The issue may be related to an air leak, weak pump, or defective pressure switch. If the issue is more than an obvious air leak that you can easily repair I would recommend having a qualified tech check system with a pressure gauge to make sure the pump, pressure switch, and air regulator are operating properly.
  1. The most common leak is the large blue hose going from the air tank to the air regulator and then over to the distribution manifold.
  2. The second most common leak is from a sticky Y19 condensation valve on the stem of the air tank.
  3. The third most common leak is the union fitting holding on the pressure switches.
  4. The fourth most common leak is the starting sphere on the pump.
  5. The fifth most common leak is the air regulator.
  6. The sixth most common leak would be a defective air ram.
  7. If no leaks are obvious and the pump builds pressure to the high side of the green on the air regulator then the issue is with the pressure switch S27.

Q: I have an SM74. The blanket wash we use is Sapphire wash, #CN 11100002. It is slow to dry after washing blankets. Could you recommend one that would dry faster for this press? We have the one Heidelberg recommends for our QM press and are not sure if it would work on the SM. It seems to dry quicker. The pressman wanted to mix the 2 together, is that an option?
A: It is not recommended to mix the 2 blanket washes. Only use fogra approved washes. Please take a look at the following link for alternative washes that are approved by fogra.

Q: We have recently bought a SM 52 2 color (no CPC). On most of our jobs we are getting ink spots that repeat up the sheet. We know they are coming from the Form dampener. We are getting new form dampeners because the ones that came with the press are somewhat old and suspect. The only remedy we have is to remove the dampeners and hand clean them but this is only a temporary solution. Are we making the right assumption with the rollers or is it more of a settings problem? We had very little tutorage with this press so we are just winging it to a point as far as settings go. The problem is applicable to both decks.
A: The condition of the water form roller, water pan roller, and the first inking form roller are all very critical to the print quality. Please review to see if you have left out any of the steps in the roller adjustments for the dampener.

Q: I just installed my SM 52-4 and the electric panel says 200 v, while my electric power in Indonesia is 380 v, I’m concerned that I will fry my machine.
Do I need a transformer to step it down, or have multi voltage to adjust it? It’s originally from Japan but my seller from New Zealand said it is okay to plug into 380 v but I am still concerned.
A: Without a serial # for the press I cannot get the specs on the press to confirm the answer.
I would suggest you order up the correct schematics for your press and then have your local power company set you up with the correct power for the press.
This may require installation of matching transformers or a different power service to your location.

Q: How do you get a 1982 MOVP 4 color sheetfeed to feed newsprint without stopping? The feeder just trips off after feeding about 7-10 sheets. It does the same thing with any stock of paper.
A: This sounds like a vacuum leak or a sticky sniffer piston. First, make sure you don’t have any suckers turned on that are not being utilized. Second, check the vacuum system for any leaks. Third, check sniffer piston as it may be dirty and need to be serviced as it will get caked up from powder and paper dust.

Q: Is there a way to shut off the double sheet detector on side guide CD 74?
A: Caution - Risk of damage to press!
When the ultrasonic double sheet detector in the pull lay has been switched off it may happen that double/multiple sheets enter the press and cause press damage. Use an alternative protection system when the ultrasonic double sheet detector in the pull lay has been switched off. An alternative protection can be guaranteed by activating optional systems for the detection of double/ multiple sheets. Optional systems can also be retrofitted.

Q: We are starting to get some image ghosting on our QM 46-2.
We occasionally get this when doing envelopes but now it’s occurring on a 2 color business card job (110# cover) that we have done for years. Is there an easy answer? (Maybe water roller wearing or something of that sort)?
A: Ghosting can be caused by rollers, ink or water.
1. Clean rollers regularly (these 3 items are suggested for cleaning your QM46 rollers and they can be ordered through Heidelberg Consumables).
  a. Saphira Presswash Printmaster
  b. Saphira Roller Conditioner
  c. Saphira Calcium Rinse
2. Adjust the rollers regularly; make sure the form rollers are set tighter to the distributor rollers than to the plate and shim the rollers to eliminate lateral side play in the journals.
3. Replace plastic track cams if they appear cracked or worn.
4. Change rollers if they have gotten too hard or too glossy to transfer ink correctly.
5. For ink, employ high pigment inks
6. You may try to reduce the quantity of dampening solution being used (smearing limit

Q: Our QM46-2 does not bring the feed table up quick enough for 290gsm or higher weighted sheet, even when the pile height is set to the highest setting. All other weight under will run fine. What is wearing out and can we replace it?
A: Below are listed 4 small items that affect the operation of the feeder pile. These items are fairly simple to replace and only require a few tools. If your issue is not corrected by replacing them I would recommend onsite service .
1. Check the A1.017.533 /01 Guide piece {On the pile scanner assembly operator side of feeder}
2. Check the 00.530.0222/ Spring pin "3x20" {On the pile scanner assembly operator side of feeder}
3. Check the 22.015.026 / Pawl (22.015.026F/01 ) {On pile lifting assembly non operator side of feeder}
4. Check the A1.017.084 /01 Grooved pin {On the pile lifting assembly non operator side of feeder}

Q: I have a QM 46. The blue hard roller in the 1st water unit has a buildup and/or oxidation on it. What will clean and restore this roller?
A: These 3 items are suggested for cleaning your QM46 rollers and they can be ordered through Heidelberg Consumables.
1. Saphira Presswash Printmaster
2. Saphira Roller Conditioner
3. Saphira Calcium Rinse .
Be careful not to scrub too hard or use an abrasive on the rollers as you can affect their hydrophilic characteristics.

Q: I have a 2 part question. Realistically, can you print short run (500) 4c process color work on 80# felt and or 90# index, 12.5" x 18", 4c/0 on Old Style QM46-2 serial # 958025 - real world, not lab/class room.
If no to first question, what is the most economical alternative?
A: If the press is in good condition and the operator has the skill sets, it is possible to produce pleasing 4 color work, but it is not the same quality work you get off a QMDI, GTO or SM52. Not knowing your press or the operator or what level of 4 color quality you are expecting it would be your judgment call.
If you are planning to go after this type or work repetitively I would look into a Speedmaster SM 52-4 Anicolor.

Q: I ran a heavy weight C5 envelope on a single color GTO 52 and since then I cannot get normal 80 gsm -100 gsm paper to run properly. The paper feeds into the front lays and then something pushes back one side of the paper resulting in the paper going into the grippers on an angle of about 15 degrees. This causes problems at the delivery end and of course the actual print on the paper is not squared. Hope you can suggest a solution.
A: Sounds like the transfer gripper is no longer parallel and you will need a tech to remove the transfer gripper and make the repair.

Q: On a QM-46-2 the impression will not engage when running single color on unit # 1, usually will engage when running 2 colors. It can be engaged manually by applying a little pressure to the air cylinder that engages the impression. I have replaced the air cylinder to no avail. It has plenty of air pressure. Could this be an electrical problem? Also what is ERROR-1 15-10?
A: I would check the lever that is attached to the blanket cylinder shaft and the Y1 linkage as it may have a broken weld or loose pin , and if it is ok then I would check the blanket cylinder bearings.
Error -1 15-10 means incorrect speed behavior during acceleration , if the drive belts are good and tensioned correctly I would do a speed compensation SF 93 on the main drive.

Q: I’m having pallets sticking together not set off but very tacky after printing the spray is working. but I have noticed the anti static box is not working and I have three anti static bars in my delivery (10 col 74 cd) if these aren’t working can this be the cause.
A: The anti static bars could affect how the sheets deliver but they should not make the stack turn into a brick, if you are sure you are getting a good even powder spray on the sheet and you have good balance on ink and water and if you are running a coater it could be an issue with the hot air knife system.
Suggest checking for loose or cracked hoses in the delivery area if you have no additional errors occurring.

Q: I am having a problem in the PU1. When I put the press into production mode, I notice water back tracking into my inking rollers. As a result it starts to wash out, if I crank the ink up it washes out even more. I know that my water in my pan is not spilling out. My plates are extremely wet. I have checked the stripes on all of my water rollers, and they are stripped by the book. This happens after 500 impressions. Could this be a problem in my inking rollers being out of whack or is this something else? Please help, this problem has just started this past week, before that I never had a problem.
A: As this is happening after 500 impressions, the rollers may have become sensitized causing them to react with the water. After performing a normal press wash, try cleaning the rollers manually. Remove the rollers from the inker and the damper and clean them. Also clean the hard rollers that are fixed in the press by hand using these 4 steps:
  1. wash with a water miscible roller wash
  2. rinse rollers with warm water
  3. clean rollers with metal plate cleaner
  4. rinse rollers with warm water.
Be careful not to scrub too hard or to use an abrasive on the rollers. When finished the rollers should have a velvety feel. After the rollers have air dried, reinstall them and check roller adjustments as they may have changed after being cleaned manually.

Q: Could you please help identify a problem with my QM 46-4? When it goes to impression, it will shut down automatically and reboot as if I had just turned on the master switch. I observed that the display at the console goes off as well but it will pass paper freely without impression. It also will go into impression on single units with up to 30 sheet before shut off. The funny thing is, it has not given us any error on S-56. What could remedy this? It is a plus version 1999 made.
  1. The SVK3 board may need to be replaced
  2. The press may have a short
  3. A 24 volt dc component of the press may be shorted internally
With the power off check connections on the SVK3 board plugs X6 and X7 ; and check connections on the ZTK board plug X7. These 2 boards are located on the left wall of the second electrical box. If you are not sure of the location, refer to your parts book. If these plugs are yellow with red caps you may wish to unplug them from the board then remove the red cap and reseat the blue wires by pressing on them with a small flat blade screw driver. After doing this, make sure all other plugs on these 2 boards are firmly seated. If this does not help please schedule a tech to trouble shoot the boards.

Q: I operate a 2 color QM 46 and I?ve been having a problem with tone bars that occur on the blanket about eight inches down from the gripper edge. They seem to be more pronounced on PU2 but have shown up on PU1 also. The tone bars eventually show up on the stock I?m running and are more apparent on the operator side. I have checked dampening roller pressures and they seem to be OK. I was thinking it may be a plate problem but I?m not sure. Any suggestions on what it might be?
A: A tone bar that appears about 8 inches from the gripper could be related to A: The water form roller, B: The #3 ink form roller, C: The blanket cylinder to plate cylinder bearer pressures.
If the rollers are in good condition and correctly adjusted and the mark is more apparent on the operator side and is common to both printing units I would suspect the blanket cylinder as it is common to both print units.
I would suggest that you have a tech check bearer pressures with a CONPRESS MEASURING DEVICE. The measuring results have to be in the range of: 960 - 1060 for QM46. It is very important that both sides of the cylinder have the same level / are parallel! (The maximum allowance between OS / DS is 100 units). If the measurements are not in the acceptable range and the tech is not able to bring it into the acceptable range by adjusting the bearer pressures I would suspect that the cylinder bearings are needed.

Q: Maybe you guys can help me, I am in Houston, Texas running a printmaster46, I am having trouble with the paper guides. As I try to set my paper guides, it gets to a stop where the guides will not move until I manually move them with a wrench. After it passes the tight spot, the guides move freely, I have cleaned everything grease open the non operator side cover where the chains are and I cannot see what keeps it from moving freely, chains, gears and sprockets for the chains do look fine, please help me. Thank you.
  1. The issue may be related to powder build up in the threaded spindles that move the tall feeder side guides.
    1. They are hidden behind the silver diamond plate that the lead edge of the paper pile rest against and are easily over looked as you cannot access them easily.

  2. Issue may also be related to dry ink build up in the threaded spindles that move the top 2 feeder register guides.
  3. Issue may be related to powder build up in the threaded spindles that move delivery side guides.

Q: Ink image is building up on the refined cylinder jacket on my 2/c Heid 74 perfecter and transferring back onto the sheet. This is a new jacket. I did not have this problem before replacing jacket. Iâ??m using the same blankets, ink and font.
A: I need more information to be of assistance, but from your description here are 2 possible scenarios.
#1 Is the image building up outside the area that the sheet covers and then working its way into the sheet?
  This could be due to the plates on the 2nd unit picture framing and transferring ink to the blanket outside the sheet contact area and then eventually building up enough ink to the point that the ink covers the impression cylinder, and then migrates back underneath the sheet on the cylinder jacket.
#2 Is the ink on the back side of the sheet building up and offsetting the sheets?
  This could be due to improper coating on the cylinder jacket from the vendor or maybe the jacket needs to be cleaned and conditioned.

Q: I have a 2006 QM46-2 that has impression cylinder gripper issues. The two outside grippers are in spec, but the six inner grippers open too soon and close too late causing feed issues. Is there a way to adjust the individual impression cylinder grippers?
  1. Each of the grippers have 2 adjusting points.
    1. The small screw underneath each gripper is used to put the gripper in basic position and then to make the fine adjustment.
    2. The large screw on the clamping piece is used for setting the pretension on the gripper by compressing the internal spring of each individual gripper.

  2. The small griper plates and the compression springs on each gripper may need to be replaced from your description as they will fatigue with age and produce the same effect you have described.
  3. I do not recommend the operator attempting this repair if the press is operational, as you could make matters worse and put the press completely down.
  4. I suggest scheduling a service call and requesting these parts be sent on consignment in case they are needed for the repair.
    1. 8x 00.540.0747/ Countersunk screw "M 4x10"
    2. 8x A4.011.035 /01 Small gripper plate (A1.011.020B/)
    3. 8x 42.011.026 / Compression spring

Q: When running a QM 46, the printing unit (over the delivery) ink roller train will start collecting water on the edges and eventually spill over. Sometimes there will so much water the catch pan under the roller train will overflow. We have checked all the roller settings. We have cleaned all the roller ends in the dampening system. Do not know what to do next?
A: PU1 may overflow for a variety of reasons.
  1. Plastic water tray may get distorted
  2. Plastic water bottle may get distorted
  3. Plastic cap on water bottle may not seal
  4. Water rollers may have become sensitized
  5. Gaskets on pan roller may not seal
  6. Leaf spring that pushes the gasket forward the water pan roller may be weak
  7. Pan roller bearings may have backlash
  8. Water control shaft under pan roller may need cleaned
  9. Rollers may need adjusted or replaced
  10. Guard that the water bottle rest on may be bent

Q: My Heidelberg GTO 46 will not feed any paper at all either via control lever or by "Paper only" switch, There is no suction. The press runs fine and blows heaps of air through separators it will just not engage into paper feed. How do I fix this?
A: The press can feed from two places. The operating lever that turns the press on and then to impression and the paper feed switch on the end of the feeder.
There is possible a bad vacuum solenoid, defective or misadjusted contactor that activates the solenoid or the missing sheet detector..

Q: Why will the delivery not go down on the QM 46?
A: If the B1 sensor on the delivery jogger does not light up when blocked it may need replaced. If the B1 sensor on the delivery jogger is lighting up but the delivery table does not go down automatically.
Please check the ratchet and solenoid inside the red box , as you may have a bad solenoid or worn ratchet assembly preventing delivery from going down.

Q: What does the code 12-36 mean on a QM-DI?
A: It usually means that the A4.114.1070 Power driver board has failed but sometimes it is the breaker that protects it has tripped or the A4.114.1099 12/36/5 power supply has failed.
These parts are located in the cabinet on delivery end of press underneath the operators console.
Due to the warranty issue on boards I would have a HUSA tech make the repair.

Q: I currently run a SM52-5 which is 6 years old and done 60 million impressions. I am having printing problems like band/bar marking. The press has NEVER had any new rollers. I told my boss we needed new rollers, but he wasn’t for having it. We did get new damping form rollers, which helped a little. How long should rollers last?
A: There are many factors that influence roller life. Some of those factors could include chemistry used on the rollers. The amount of surfactants and calcium build up in the nap of the roller. Proper function of the bearings and proper roller settings. Over time heat and chemistry begin to break down the plasticizer components of the rubber. The roller will then begin to harden over time and this harder roller could cause interruptions in print. In your case I would suggest contacting the roller manufacturer and have them analyze your rollers.

Q: Why is the Printmaster 46 tripping out when it goes on impression, but feeds blank paper fine?
A: The QM46 may be tripping out when it goes on impression for several different reasons. The 2 most common reasons for this issue are sheet arrival angle and the sheet length monitoring function. These issues could be related to the feeder settings or the B4 sensor may need replaced. If you use SF 68 it will give you an idea of how your sheet arrival is being read by the B4 sensor. If you use SF 43 it will give you an idea of how accurately the B4 sensor is reading the sheet length. The 3rd most common reason is related to the pneumatic air pressure dropping below the safe range. This could be caused by an air leak or an improperly adjusted pressure switch. If you watch the air pressure gauge it will give you an idea of where the pressure is in the green zone or the red zone when the press trips off.

Q: We have a mis-registration between the units 1&2 and 3&4 on a SM 74-4PH 1998. Black and Cyan register fine and Magenta and Yellow also register fine. Seems like there is a .5mm stretching in the paper where magenta and yellow need to stretch open to fit on Cyan and Black.
A: This could be a problem with the paper stock. My first suggestion would be to try a different paper stock. If the issue still exists then a service technician should be called in to look at the perfecting unit.

Q: My Raptor Pro plate processor trips to off when I turn on the main switch.
A: When the main breaker on the Raptor Pro Processor trips, it means that there is a short somewhere in the electronics, motors, heater, etc. Since there is high voltage present in the processor, there is a potential safety hazard for non trained personnel to be trying to determine the cause of the short. It is advised to have a qualified Heidelberg Technician troubleshoot and repair the problem.

Q: Is there easy access to fault codes for the Printmaster 46? What do these two codes mean that are showing on my Printmaster? Error 11-01 and 11-06.
A: Error 11-01 shows the crank handle in the feeder is engaged or the S19 switch, which is activated by the handle, is activated or in need of replacement. Error 11-06 shows an issue with the double sheet detector, which may require a service call to completely address the problem. Check for proper alignment of the light barriers and that the double sheet detector box operates properly. There is a light on the box that should respond to how the dial is set. If the light stays on and is unresponsive the box may be bad or getting a reading from a lost sheet of paper. Also check that there is not an obstruction of paper blocking one of the light barriers under the guide plate.

Q: We have a 1999 SM 52-2 and we have water dripping from the water pan of the second unit. What do you think is the cause of this problem and what can we do about it?
A: To start diagnosing the problem, first check to be sure the amount of water flow is not set too high. If the water flow is set correctly, the return could be backed up. Check to see if the return is accepting the water that is set in solution 1. Both are adjustable at the water circulation tank. If the operator is not comfortable with this adjustment, you could prearrange a service visit. If the drip is coming from the end of the pan, the water level is most likely too high; if it is coming from the middle of the pan it is most likely condensation. Also check the pan insulation to make sure it is not missing or damaged.

Q: We have an old [late 70’s] GTO 46. It had molleton covers on the water system and we replaced the water system with a Kompac unit. The water system is much easier to control now. However we have always had trouble keeping the edges of the plate clear of ink, mostly the operator’s side. This problem still remains after installing the Kompac. We are wondering if the plate cylinder is worn or if there is something else we should check.
A: Roller hangers are a common problem on GTO/MO machines. It sounds like the roller hangers on this press need to be replaced. One of the water forms needs to be covered to a length longer than the width of the plate, even though this is not normally done on GTO or other conventional systems. While the roller hangers could be the solution, this is a problem that has multiple possible origins and would require a technician looking at the roller hangers to diagnose the problem fully.

Q: : I am having trouble with the ink fountain roller on the first printing unit on my QM46-2. It will stop turning when running the press. When I move the ink fountain lever there is a snap on the operator’s side, like something is sticking. Is there anything we can do before having to have it replaced?
A: The metal stop that the clutch rests against may need to be adjusted so that the clutch doesn't travel too far, causing it to bind. The other thing to check for is wear on the fountain roller where the clutch rests. The overrunning clutch will need to be removed to check this. The shaft should be smooth without any defects. If defects in the shaft are apparent then the fountain roller and clutch will need to be replaced.

Q: We have a QM46-2 which is not bringing the feed table up consistently. Even when the pile height is set to the lowest setting, it will bring the pile up to max height. How can this be adjusted and/or what parts should I look at for wear?
A: It sounds like the lever that operates the bail bar is worn and in need of replacement. Put the bail bar in the lowest position and then gently push all the way up on it. You will probably feel a spot where it moves very freely, then has some tension on it. Allow the bail bar to come back to the down position very slowly until it stops, then by hand pull down on the bail bar and you may notice that you can pull it further down.
I would recommend having the pile height lever (MV.025.244/03) and the guide piece (A1.017.533/01) onsite for replacement by a Heidelberg Technician as there are timing requirements that will need to be reset once these parts are removed.

Q: The double sheet detector will not set on our Printmaster QM46 /2. After removing and cleaning the deflector, the light still will not go out. What is your advice?
A: It’s possible that you have a lost sheet underneath the lower guide plate that is being read by the sensor causing your issue. If you do not find a lost sheet, we recommend having the help desk order you a new VD box and new light barriers for a Heidelberg Technician to troubleshoot with.

Q: I have a QM46-2 and I have been having toning problems. I've reduced my ink stripes from 4mm to 3mm and it has not helped. I have reduced my water form to a 3mm stripe and I?ve also deglazed my ink rollers. I don't think it's a packing issue because when I do the breakaway on the press, it performs properly. I've tried various fountain concentrates at the present time I'm using bouetcher 3002 solution. My toning problem still exists, but is workable. My ink rollers are approximately 3 1/2 years old. I was wondering if I can use a scotch brite pad to rub down my water pan rollers. I'm at my wits end. What other advice can you give me?
A: Without seeing the machine to check the condition of the rollers and ink train system I can give you some things to check.
With proper care Ink and Damp rollers usually last approx 12 million impressions before they need replaced. Using a quality roller lube will extend the life of your rollers. If you are not using roller lube when you should then the pores of the rollers get damaged and will not carry ink and water properly to your plate. The stripes from the ink forms to the oscillators should be set to 4mm. The ink forms should be set 3mm to the plate. It is important that the stripe from the forms to the oscillators are heavier than the stripes from the forms to the plate, this way the ink train is driving itself and is not being driven by the plate cylinder. Also check the end play of the ink forms so that they are not oscillating creating a scrubbing action on the plate. The oscillator cam needs to be inspected for wear along with the cam followers on the ink train.

Q: How do I get the non operators side cover off a 2 color QM46? Either way I try the posts for the handles get in the way.
A: If this is a PrintMaster then you need to loosen the two 5mm screws located on the inside of the feeder frame for the rear and side air. Then slide them inside the cover by means of the slotted space in the side frame where the 5mm screws were located. Also you should loosen the powder unit and move it forward an inch to gain space in the delivery area. Make sure the sucker bar is in its lowest position. After all of the screws and knobs are removed then you’ll start from the feeder pulling the guard off at a bit of an angle and then move it forward to remove the front jogger post from the guard.

Q: My Printmaster QM-46-2 is showing a general fault and will not clear. The compressor indicator gauge is centered in the green and all the guards are closed. Neither incher is on. I tried opening and closing each of the guards and heard them click open and closed. What now?
A: We need a little more information to provide the correct information for you but it sounds as if you possibly have a popped breaker for the pneumatic pressure switches. Presses S for service function on the control panel, then enter in 56. This will display any fault codes. If the display then shows that you have an error 11-05 then it is probably the breaker. If this is the case then the power should be shut off and the electrical cord disconnected so the machine is locked out for safety. Then open the front electrical cabinet panel directly under the operator panel with the supplied electrical key. Have a look at the HVK board. This board is labeled HVK and has a few pop up type of breakers on it. They are somewhat rectangle in shape and have a push button on the middle of it somewhat like you’d find on the tip of a pen. Push the button in. You?ll feel a click if they were popped. Now you can reinstall the electrical panel and power up the machine to see if this corrected the issue. If not we can easily identify your issue from any errors shown in the SF 56 display. Use the plus button to toggle through the errors and provide a list of all errors shown.

Q: Our QMDI 46-4 classic press is stopping during a run and the fans will cycle on and off. After the fans cycle the press is ready to run again. The screen does not go blank during the stop and the press does not have to be restarted before it is ready to run, but this is happening several times a day. Any idea what is causing this?
A: This issue sounds like it is being caused by a 24 volt short. We suggest scheduling onsite service to check out the press as the circuit boards such as the SVK3 and the ZTK may get damaged if the issue is allowed to go on unchecked. It is helpful to have spare parts, such as the aforementioned boards, on hand when troubleshooting issues such as these. If the SVK3 and the ZTK boards do need to be replaced, they will be covered by a one year warranty if a Heidelberg service technician installs them.
If you would like to schedule a Heidelberg service technician to help you with this issue, please contact us at:

Q: I have a QMDI-46 classic, we want to run a sulphated fine cardboard of 12 points of 236 grams. Is it possible? I just don’t want to have problems with the blankets and gripper plates in the future when I want to put thinner paper to print.
A: The QMDI’s limit on material thickness is 12 point so you should be fine there. As for it creating any issues with other jobs on different substrates it would be no different than if you did so on a conventional press. You may eventually wear your blanket down a bit quicker and possibly cause an issue if you were changing paper widths (Cut lines) but as I said before it would be no different than on any other press.

Q: NEW! We have a 6-unit SM 72F and a 4-unit SM 72V, all manufactured between 1980 and 1990. We are planning on relocating the machines to our new factory which does not have air conditioning. Can we place the machines in the new factory without air conditioning? What is the recommended temperature range for the machines to operate properly?
A: Both the temperature and relative humidity play a role in the pressroom. In printing, consistency is crucial for success. The temperature of your pressroom should remain between 68 and 76 degrees Fahrenheit and the relative humidity should range between 35% and 55%. These criteria must be met in order to ensure top performance of not only your Heidelberg presses, but also the substrate that they print on. Please consult with our Systemservice experts if you have additional questions about your move or equipment.

Q: NEW! We are experiencing repeated trip out with the breaker for the compressor on our QM 46. When the problem began this occurred maybe once a week, but more recently it happens several times per day. Do you have any solutions to this issue?
A: You may need to replace your HVK board. There is a new version HVK board that is fused at a higher rating to replace your old one. Also, the pneumatic pressure switches may need replacing. We recommend having all of these electrical items replaced by a Heidelberg Technician. The newer pneumatic pressure switches are wired in a different pattern, and we therefore do not recommend repairing this without the support of a Heidelberg Service Technician.

Q: FEATURED - My QM 46 randomly shuts down in the middle of the run. When this happens, the screen goes dead. To fix this, the entire machine must be restarted, which resets the plate status. This results in a forced plate eject and we lose all of the saved settings for the job. Do you have any idea why this is happening? Is there a way to tell the machine that it DOES have a plate loaded?
A: All of these issues are related and can be resolved with the same fix. The wiring harness has a loose connection. You can either replace the wiring harness on the X7 plug or have a Heidelberg Service Technician reseat the wires on the existing plug with a special amp tool. The latter would be a less expensive fix. This will fix the issue of the machine losing the 5 volt connection which causes the memory loss and the screen blanking out. As far as telling the machine that the plates are still loaded, the only way to do this is to go through the autoplate method of lining up the cylinders and remounting the plates. The plates do not have to be removed to do this. Once the wire connection is fixed, the plate issue will be solved as well. If you would like a Service Technician to help reseat the wires:

Q: NEW! The light at the feeder of my QM 46 went out. I bought a replacement bulb for it but it still won’t come on. The light box on the press has the number 11E1 on it. Is there a special light bulb I need or can I use any replacement with the same value as the one that comes with the press?
A: You can get an aftermarket bulb but you have to make sure it is a heavy duty bulb or it will blow out immediately. To see the difference visually, look at the prongs that plug the bulb in and follow them up to the filament. The prongs that go up to the filament go across continuously, become the filament, and come back down to the other prong. With the light duty bulb, the filament on top is a separate wire and much thinner than the posts.

Q: NEW! Recently the cylinder on our 1985 GTO 52 has been hard to turn while trying to change a plate or blanket, regardless of whether it is in manual or we use the electric button. I have no idea what is happening as it has worked fine in the past. Do you have any suggestions to fix this problem?
A: It may be that the brake on the main drive motor needs to be adjusted. We would suggest you have a Heidelberg service technician visit to fix this issue.

Q: FEATURED - I have a 2.5 year old Printmaster QM 46-2. The first unit has a permanent water shock mark about 3” down from the gripper edge, running across the entire sheet left to right. Running a solid in this area shows a lighter excess water mark about 2mm or less in width. Nothing I have tried will eliminate the mark, including replacing all of the soft rubber dampening rollers. Do you have any suggestions to fix this problem?
A: The following are remedies for Stripe Formation Conditioned by Machines:
  • When maintaining the rollers, only use appropriate cleansing agents. The weekly application of a wash paste removes lime deposits, and will regenerate the rollers.
  • Adjust the rollers in accordance with the instruction manual. Inspect the adjustment regularly.
  • Change used rollers. The rubber surface of older rollers becomes glossy and over-smooth. At the same time, as their hardness increases, the edges bulge out in the shape of a trumpet. More pronounced abrasion becomes evident.
  • Adjust reciprocation of the ink form rollers
  • The dampening distribution cylinder must be kept clean and receptive to water.
  • The roll bearings must be in fine working condition (no play, no sticking).
  • Lubricate the roll bearings.
  • Set the ink form rollers as gently as possible on the printing plate. By doing this, impacts stemming from the run-on and run-off edges are reduced.
  • The bearer ring should be kept clean and grease-free.
  • The calibrated underpacking should be clean, cut in a format to fit, and correctly inserted.
  • Clamping between the plate and the blanket should range between .1mm and a max .13mm (.004-.051 in).
  • Clamping between the blanket and the counterpressure should be set in consideration of the surface of the printing stock. Avoid clamping that is set too high.
  • Always prepare dampening solution according to instructions (pH value and conductivity). The Ideal dampening solution has a water hardness of 8-12 dH, a pH-value of 4.8-5.5, and a temperature ranging from 50-59 degrees Fahrenheit.

Q: NEW! Occasionally, I have trouble with the plate not coming off of the 2nd unit of my Quickmaster 46. The indicator light says that I have a plate jam (error SF 3+7 92) and I have a lot of trouble getting the error to clear. Sometimes it will clear right away and other times it takes forever. Do you have any suggestions as to how I can clear that easily?
A: Your plate may not be coming off all the time due to the following.

First, it may be that the AutoPlate assembly needs to be adjusted. It could also be because the plate clamp height is not fully open. When clearing the plate error, you must take extra special care that you are following the exact sequence each time.

We would recommend a service call to ensure the proper operation and adjustment of this plate assembly.

Q: Is there a retrofit possibility for installing a laser slit fountain on a Quickmaster 46? I have a project that I could run on the Quickmaster, but I would need to have better control of ink distribution. I’ve seen that there are third party replacements for Quickmasters and wondered if I could add the laser slit ink fountain from the Printmaster 46 to my Quickmaster 46.
A: There is no retrofit kit for this, but it is possible to do. To add the laser slit ink fountain from the Printmaster 46 to a Quickmaster 46, you will need to completely replace the ink fountain as well as the ink fountain roller. A Heidelberg service technician can ensure all parts are correct and the conversion is within tolerence.

Please contact us if you would like assistance in this project.

Q: I am having trouble with ink "piling" on the water metering rollers on a GTO-5 with DDS dampening, is this an ink/fountain solution issue or a roller adjustment?
A: Ink piling is normally an ink/dampening solution issue, where the ink is not able to withstand the strength of the fountain solution, either due to the mixture ratio or the type of solution altogether.

If it is the same solution you run normally, you most likely have a contamination issue that can be taken care of by washing the press with HOT WATER AND WHITE VINEGAR, (do not use a chemical deglaze or the like, as it is very hard on the rollers). The hot water will chase out the water based contaminates and the vinegar will chase the mineral deposits out of the rollers.

It may be necessary to do this several times to get the problem to go away, and it should be done on a weekly basis afterwards to prevent further contamination problems.

Q: I have a SM 74 that I’m having trouble getting a Color wash done. I’m using my Yellow unit to go to varnish. Can you outline a color wash procedure? I have washed 3x and still yellow.
A: I would suggest for a color wash up procedure to try the following:
  1. After the initial wash up allow a roller paste to run onto the rollers for several minutes.
  2. Rinse rollers as you normally would.
    • As an alternative to the roller paste you could use opaque white to pull out the yellow ink.
    • Double check roller setting to ensure proper contact points.

Q: We are buying an MOV and I was wondering what to look in the machine as far as it’s workable condition is concerned.
A: The Heidelberg MOV has been a strong printing machine for thousands of customers around the world. The M Offset had an end of life in 1995 when the Speedmaster 74 was introduced to improve quality and reduce production time. While there are many M Offset machine still producing in the industry today one can never be sure of the condition of a used machine without an evaluation. Heidelberg Service can provide a service to evaluate any used press and provide a detailed report.

Q: I run a 2-color Heidelberg GTO 46 press with Kompac water systems. Unfortunately, I’m having some problems and I’m hoping for help. This is what’s happening: I think the problem is called chalking. When I overprint a second (or third) color, it does not print solid. There are spots in the printed areas that are not taking ink. Can you please help me with the solution?
A: Care needs to be taken on many offset printing presses with the amount of spray powder that is applied on the first pass of a multi pass job. Excess spray powder can create difficulties in applying a second color due to a build up on the blanket. This will be apparent if the blanket has a white caulk coating on the surface. This can be removed with a water dampened sponge.

Q:  I’m having trouble with my coater. It seems to come on impression with different pressures between the chrome metering roller and blanket on the coating unit. I can run all day with the pressure up around 100 and the rate about 60 or 70, stop, load more paper, take off, and pressure will all of a sudden come on much heavier. I’ll have to back the pressure off to about 60 and the rate down to about 10 to get the same amount of coating to keep the sheets from sticking together. I can start back up and it will go other way. Not having enough pressure between the chrome roller and blanket, I have to put it back to a pressure setting of 100 and a rate of 60 or 70. I have noticed when this happens, the speed at which the roller is spinning with the blanket also changes.

The pan is always consistent with the rate you have it set for, the problems occur with the metering roller. When I need less pressure and a lower pan roller speed the metering roller is turning the same speed as the blanket. When I need more pressure and a higher pan roller rate, the metering roller is turning slower than the blanket. You can even see streaks, as if the blanket is being drug past the metering roller. This has been going on for a while. If you can give me any help with this it would be greatly appreciated.
A: I’m not sure of the press format size you have, but in general, a two roller coater requires a setting between the pan roller and chrome roller of approximately a 4-5mm stripe. Next you need an aqueous coating with a viscosity of approximately 18 seconds when measured with a number 3 Zahn cup or 36 seconds with a Din 4 cup.

The next critical step is to make sure you apply kiss pressure from the chrome application roller and the blanket cylinder and kiss pressure from the blanket to the impression cylinder. The easiest way is verify kiss pressure is to perform a break away to see when you have adjusted the DS and OS the same.

Remember you’re applying a coating which requires only 2 thousands squeeze compared to printing which requires 4-6 thousands pressure. The breakaway approach also works to reduce the hard edge of coating at the tail of the sheet and should be done with the blanket to impression cylinder as well.

Q: What is the timing for the change over for the impression cylinder to the delivery grippers on a QM 46?
A: The settings requested are a factory setting. Because we don’t know if the machine is set to a true “0”, we can’t accurately give this information.

Please consult your local Heidelberg service department by calling 800-437-7388.

Q: I have a new press operator that runs a QM46-2. He has a habit of stopping the press by opening a guard (in effect an emergency stop) instead of using the stop button. He also tries to run the press at high rates of speed in spite of trips caused by the paper not feeding correctly. This can cause the press to come to abrupt stops many times a day. He doesn't believe this does any harm to the press. My question is, does it harm the press in the short or longer term?
A: While a hard stop of the press doesn’t affect short term quality of the press, there is a reason that Heidelberg along with other press manufacturers have gone to a soft stop procedure, which brings the press to a gradual stop. Keep in mind this soft stop is also used in $5,000,000 presses with gears and components multiple times stronger than a QM 46. The soft stop will ensure the longest life of the main components. The safeties incorporated on the machine are designed for the safety of the machine and of the operator. It is not recommended to use these for the general operation of the machine unless needed. I would suggest a change in daily habits.

When it comes to the paper travel and the miss feed of sheets, the machine stops quickly to prevent damage when a sheet enters the press at the wrong degree position. Nothing to worry about here.

If you continue to have sporadic feeding issues, I would recommend having a Heidelberg service technician onsite to address these issues.
You can call 800-437-7388.

Q: The compressor on our QM46-2 holds air and works fine when under impression. However, if the press stops running and sits idle for a few seconds to make an adjustment, the press will not operate until the compressor kicks back on and rebuilds air. The air pressure does not appear to be leaking. It appears there may be a sensor that is not telling the compressor to kick on to keep the air at the correct pressure.
A: The pressure switches S24 & S27 probably need to be adjusted or replaced.

The part numbers are:
A1.102.1551/01 – Pressure switch
A1.102.1531/01 – Sensor

Q: I’m having a problem setting the roller in the PU1 unit, the #1 form will not set to the plate and the #3 form will not set to the distributor roller. I have gone though the whole set up and settings as per the book but can’t get the setting right. Can you help?
A: If you can no longer get one or more of the form rollers to make contact with the oscillator rollers or the plate, the rollers have shrunk and are in need of replacement. The rollers can be ordered through the Heidelberg consumables department at a discounted rate by calling toll-free 888-472-9655.

Q: The delivery table on our QM46-2 continuously lowers after the first Ľ” whether paper is feeding or not. What could be causing this?
A: If the B1 sensor was an issue, the press would go into print suspend after 50 sheets and not continue to drop. The delivery pile lifting assembly Y17 may need to be cleaned or the shaft assembly may be worn to the point that it no longer has enough friction to hold the pile still. In that case, it may require the shaft and gear box be replaced.

Q: I have a question about your video on running envelope. When I set up my QM46 like the video shows, the envelope jams, jumps over the stops and misses the grippers. This happens even if I adjust the sheet advance back. What can I do to fix this problem?
A: The pile scanner may have excessive wear or be adjusted incorrectly. Another cause might be that the 3/2 way vale may need to be serviced or the idler rollers for the sucker bar may need to be replaced.

Q: I am trying to run 12X18 on a Printmaster QM 46 and one corner is getting dog-eared. Do you have any idea what could be causing this?
A: Usually dog earring on a Printmaster QM 46 is because of the front side blowers being set all the way down. These can get bumped when working in this area. Move the front side blowers all the way up and then about 1/16” down. Then check for positive pick up from the air blast.

Q: I have QM 46-2. My question is about the packing and meeting the right circumference. I have 8mil poly plates (.20 mm) my blanket is 1.95 mm if I pack so that I have a .10 mm squeeze I am -.10 mm under the cylinder undercut and I need to max out on the squeeze of my impression cylinder. If I over pack with a .35 mm or a .40 mm I get a nice solid but I am way over packing. Is this ok? Or what do you suggest?
A: It is not a good idea to over pack the blanket to achieve a good impression between the impression and blanket cylinder to the sheet of paper. You should always pack the blanket according to the plate thickness. You need a .004" to a .006" transfer squeeze between your plate and blanket cylinder to achieve the best printable dot possible without having too much dot gain. If you do not have a good transfer between your blanket and impression cylinder after doing so then you will need a Heidelberg service tech to make a mechanical change between your impression and blanket cylinder to correct this. By over packing you may get a better solid but it will only make your screens look muddy.

Q: I am having a printing position problem on our QM-46-2. When the plate is mounted and ready to print, the image on the plate and on the blanket is in the correct position. The problem lies in that when I go to print the job the image is too far forward and is cut off. I have to move the circumferential register adjustment knob for PU1 and PU2 from the 0 start position, to almost all the way from the gripper to get the whole image to print. The press is feeding and delivering correctly. What would you suggest to solve this problem?
A: When you change the timing of the overall circumferential system it changes the timing of the feeder, impression cylinder and delivery together verses the printing units. This is why the paper transfers fine but may not print to your specs. It sounds like either the image is not in the correct position on the plate or that something is wrong with the timing of the impression to blanket cylinder. I would recommend having a Heidelberg service technician onsite to further diagnose the situation.

Q: What would cause head stop marks on a # 10 envelope? I adjusted the sheet arrival adjustment all the way to negative 2, but I’m but still getting 2 marks at the gripper edge.
A: Possible Causes
1. Marks on envelopes can be caused by the forwarding rollers if they are not adjusted correctly.
2. Marks on envelopes can be caused by the erratic movement of the feeder pile as it rises if the customer is not using the scanner shoe on the pile scanning lever.
3. Marks on envelopes can be caused by the transfer timing of the chain delivery grippers as the envelope may be pulled off the impression cylinder before the impression cylinder grippers have released the envelope.

1. Correct feeder pile so that the table rises correctly.
2. Correct the angle adjustment on the sucker bar.
3. Correct forwarding rollers pressure and dwell.
4. Correct impression cylinder grippers so they close and open at correct time.
5. Correct chain delivery tension.
6. Correct chain delivery gripper bar.

Q: Can you please answer some of my questions about a QMDI-46 Pro?
1. Should the press be in an enclosed room? (We are a Thermography shop)
2. What would be the correct temperature for the room?
3. Should the ink be taken out every night or can it be left the ink tray over night?
A: 1) The press does not have to be in its own room.
2) The QMDI can operate under a wide range of pressroom conditions as long as it is as consistent as possible. If the press room is 72 degrees in the morning and in the 90’s in the afternoon, you could have printing issues.
3) You can leave the ink in the fountains overnight, but be sure to spray it with something like "Stay Open".

Q: I recently purchased a used QM 46-2, so I am a new user of this press. When running the double sheet/sheet length the short sheet indicator displays. Please explain what this means, and how do I correct this problem.

I have tried to adjust air blast, suction, pile height and sheet arrival but still often see short sheet displayed. Is there something else that maybe causing this problem (mechanical)? I did not receive an owner’s manual with this press.
A: Check the lens of the double sheet detector. It may have a crack or just need to be cleaned. If you would like to turn off the sheet length monitor, it is Special Function 19. This still allows the double sheet detector to work.

Q: We have a QM-46 running 12 x 18 80# Gloss Text printing 2 sides. We ran the light coverage side first, no problem. On the second side there are some solid areas and near the gripper an area that is a 30% screen. Why are suction cup marks from the sucker feet showing up in the screened area? The pressman says he has to wash the blanket every 200 sheets to get rid of the marks. What is causing it? Would using powder on the first side cause that?
A: This is simply too much powder on the sheet when it went though the first time.
  Back to top
Q: With paper jams at the infeed rollers on my QM 46-2, the impression cylinder receives an impression. Is this normal or should the impression cylinder disengage from the blanket cylinder?
A: Any time paper feeds into the infeed rollers the infeed sensor detects that a sheet of paper is coming into the machine and at so many degrees from now the grippers need to open and the cylinders need to be locked on pressure. If a sheet is jamming at the infeed, then we would look into the sheet separation before the sheet gets to the sucker tubes. The paper stack should have the top 10-15 sheets floating on air and be guided to the non operator side of the feeder side guide and be separated with air so the sucker tubes can precisely pick up one sheet and forward it into the infeed forwarding rollers. That sheet going into the forwarding rollers should be flat across the lead edge of the sheet so it doesn’t jam into the forwarding upper and lower rollers.
  Back to top
Q: continued... secondly, the first sheet printed after a miss-feed has at least a double impression from the blanket cylinder, the impression cylinder in this situation remained clean, is this normal as well?
A: No, this is not normal. The only way a sheet can have a double image is from movement of the plate cylinder or plate. If the machine had a jam at the infeed under the infeed sheet detector, the machine should go on pressure and an image would print on the bottom cylinder and therefore giving you an image on both sides of the paper. If the paper jammed in the feeder, then the machine should stop and rollers and cylinders go off pressure before the image gets to the impression cylinder.
  Back to top
Q: continued...and third, I have to manually predampen my Sliver master plates on start up, because if I don’t the non image areas fill in. Is this normal?
A: This is normal for Silver master plates or Polyester plates. They require an excessive amount of water for the non-image area to remain open on a plate, so starting the machine and letting it stay in the predampening position for an extra 25-50 revolutions is normal and will allow the Polyester plate enough moisture to remain open in the non-image areas.

Q: We have a QM-46/2 and it wrinkles 8.5 x 11 20# white bond mostly on the gear side of the press. I have changed stock and changed brands of stock. It does not wrinkle NCR, 11 x 17 bond or anything else. Any help would be great.

Follow up: I discovered that the sheet arrival was or is the problem. I now have the sheet arrival retarded (-5) as much as I can and it has solved the wrinkle problems for now. Through, using Special Function Keys 68 it gives me 2 sets of numbers, and they now are at: Top 321 and the Bottom 324.8. They were previously at Top 320.0 and Bottom 323.7.I was informed that Top should be 320 and the Bottom should be 325. That is as far as I have gotten with my problem, so far.
A: The numbers are only a reference and can be manipulated and should not be used as a true setting of the sheet arrival, only as a guide. The problem is most likely a broken gripper spring on the impression cylinder. The reason they can run with the sheet arrival retarded is that the sheets are not hitting the head stops of the impression cylinder grippers and are able to lay smoother. The press probably needs a complete gripper job.

We recommend installing new infeed wheels at this time. This is all providing that the operator has not mechanically changed anything on the feeder timing. We would also recommend for a mechanic to check the timing of the sheet arrival to make sure that it is mechanically correct.

Q: We have a QM 46-2. On the Second Unit looking at the dampening system, the first rubber roller that you'll see (Metering Roller) is building up ink on the right side starting at 1/2 inch. The more impression, the wider it gets. This problem start mostly in the afternoon when its warm, and never occurs in the morning. We are running two color black on the first unit and PMS 185 on the second unit. Only that that roller is building ink, as I have checked the roller behind it. In addition, when I disengage or am not printing, it distributes the ink properly. However, as soon as I engage it with water, the impression starts again in 1/2 ink build up. Can you suggest a solution?
A: It sounds like there are bad roller settings due to a bearing failure. The stripes may appear okay at first, but once under pressure, the stripe may be different. It is recommended that you inspect all of the bearings in the dampening unit including the pan roller.

Q: We have been using Varn Pronto for the Blanket cleaner on our QM-46-2. Lately, we have been having trouble with this being shipped to us without excessive costs. Is there another product that can be used?
A: There are shipping requirements for solutions with lower flashpoint washes. At Heidelberg Consumables, we sell only fogra approved washes. The flash point is over 142F and does not require a red shipping label. Plus, by using a fogra approved wash on the Heidelberg QM 46, you meet all of the factory recommended requirements for a blanket wash.

Q: We are experience an UV detaching pattern, and we couldn’t find the reason.

We were trying with different inks, varnish, primers and uv’s even with another paper stock but nothing happens. It seems to be some humidity trapped between the paper and the ink.

This trouble appears just when the product is on its final destination transit for more than 3 days, and with products with non cardboard covers.
A: The Expert suggests that you test the substrate using a dyne pen. You can purchase these off the internet from many suppliers.

A surface tension of 38 to 40 Dynes/cm is needed for good adhesion. For anything below this value it is impossible to guarantee good adhesion. Consider returning the substrate back to supplier.

Q: I am running a Prosetter 52, Signa Station and a Printmaster 52.

Here are the specifics:

In the Signa Station software there is a place for the gripper number to be put in. Then there is a second number put in for the "baseline".

Here are the questions:

Is the baseline the distance from the edge of the plate to where the leading edge of the paper hits the plate? If not then what is it?

What is the baseline setting for the Printmaster 52? Is that constant? What would that be called in the manual as I do not see a baseline setting in the PM52 book?
A: In a Heidelberg workflow there are 2 values that are used to determine what the baseline is. The press manual lists the values under "Print-related specifications" and the 2 values are:

- Distance between front edge plate and print start
- Gripper bite or Paper Bite

To determine baseline simply subtract the Gripper Bite from the print start.

PM 52 specs are:
Start of print = 58mm
Gripper = 8...10mm (variable...use mean value)

58mm    Start of print
-9mm    Gripper
49mm    Baseline

Q: My QM 46 is only allowing the center form to drop. Is there an adjustment I missed? The adjustment screws are not moving fully against the stops. I'm effectively printing with 1 form. This does not work with heavy black coverage.

Q: Hello, I hope you could clear my doubt, (does there) exist any "chemical free plate" for the Prosetter (violet photopolymer - silver halide). One seller told me that I could use some upgrade in the Raptor (plate procesor for photopolymer) to use this kind of plate.
A: Heidelberg provided live demonstrations on the new Saphira Violet Chemfree plate at the recent drupa tradeshow. The plates ran through a new compact cleanout unit that did not have developer or water sections since they are not needed. This cleanout unit takes up less space and uses less energy as compared to a traditional processor. The schedule to release the new plate and cleanout unit is Q1 - 2009. As for converting your existing processor, we do not yet know if this will be possible. Please consult your local Heidelberg organization when you’re ready to convert and they can give you the latest status on this.

Q: What is the correct way to set the intermediate roller on the SM-74? When I use the method described in the operator’s manual the dampener does not wash up.
A: You need to make sure the Intermediate roller is set properly to the #1 ink form. Checking the ink stripe (3mm) of the intermediate roller to the #1 ink form roller:

1) Make sure that that integration of the dampener is selected on at the console.
2) Ensure that the ink form rollers and the water form are in contact to the plate .
3) The gap of the plate cylinder should face out away from the rollers.
4) Inch the press backwards to see the contact stripe between the rollers.
5) The adjustment is the spring rod with the 13 mm nut. Make the adjustment and try again.
6) If the #1 ink form roller has shrunk too far you will need to replace it.
7) Make sure that all pneumatic pistons are working properly.

Q: I am having a problem with our IR dryer on the PM46-2. The press was installed in January of this year, but with a move of our business in the near future, we did not run power for the IR dryer. We are now in our new location and have the IR dryer powered up. The problem is, sometimes it works and sometimes it doesn't. The press goes on impression and the IR dryer doesn't fire. The temp is set for 97.5, and the read out for actual temp is low (70's to 80's). It will be working just fine and then next time I start up - nothing. One odd behavior during its malfunction is that it will fire for a second or two (like when you first turn the unit on for operation) when coming OFF impression at the end of the run, or interruption with the production button. Any ideas?
A: A common cause for the IR lamps to shut off unexpectedly is a mal-adjustment of the Baumer Jam detect sensor. Please refer to the sensor adjustment procedures for proper adjustment. NOTE: If you are repeatedly having to re-adjust the sensor, try turning the sensitivity screw counter clockwise a little more AS THE LAST STEP. A sensor adjusted too close to the edge of the yellow light going on and off could be troublesome, as the tolerance on components in the sensor may relax a little over time.

Please refer to the attachments for easy reference.

Q: I have a QM DI-46 and some of my ink keys are out of adjustment. When I zero out a tray some of the keys do not close fully, and some do not open evenly when I set the keys. How can I adjust this problem?
A: Remove the cover that surrounds the ink key levers by removing the two 2.5mm Allen head bolts located under the ink fountain.

You will see the adjustment Allen head bolts (4mm) next to each ink zone lever.

With ink in the fountain and all of the levers in the same position you can adjust the keys.

Q: Our QM46-2 Is having a few problems, just thought you might be able to help us out. When running a job and using PU2 we find a strip of 'catch up' running the length of the sheet near the operator side.

I have included a photo with this so you can see what i'm talking about. It appears in intervals of 500 sheets, when I use the blanket wash it's gone then 500 sheets later it will re-appear.

The dampeners are as close to off as possible, we have increased them but that just floods the plate etc.
A: The first thing that I would have you try is to adjust all of the form rollers and pay close attention to the dampening form roller. If the settings are okay, it may be time to look into replacing rollers.

Q: I'm having a problem with my QM 46 not getting much spray powder.

I have cleaned the lines, checked all connections and the solenoid is working. How much air should I get from the Gast pump? It is 3 1/2 years old; what is life of this pump?
A: The pump does not usually fail; most of the time if you notice loss of spray powder control there is a clog somewhere in the system. The sprayers in the powder housing sometimes can block the powder from spraying properly, or the manifold could be clogged.

There is a quick disconnect on the black powder line. I would recommend disconnecting the powder line there and test the system with special function 04 using the plus and minus buttons. If the spray comes out ok then the manifold is ok and a clog is further down the line. If the spray is weak then the manifold needs to be cleaned or possibly replaced. The only thing on the pump that should be checked is that the paper filter is not clogged, restricting the airflow.

For detailed information on the pump itself I would recommend contacting Airtech; their number is located on the side of the powder system. They will require the model and serial number which is also located on the side of the powder unit. If you are not comfortable with these suggestions, please contact Heidelberg support.

Q: We have a QM DI 46 Classic and are having a problem with a quarter inch roller stripe showing up on the black image. We have adjusted all the rollers and can't see anything wrong. What is causing this problem?
A: The mark could be due to a variety of causes, such as: the roller hangers may be worn, or cylinder bearing wear issues, or bearer pressure adjustment issues.

I suggest first that (in this exact sequence) you remove the 2nd 3rd & 4th transfer rollers; then adjust forms (2/1/3) to distributors. Then adjust forms (2/1/3) to the plate, then install the 2nd 3rd &4th transfer rollers and adjust them with the forms dropped on the plate.

Now re-check the forms to the plate and if you notice that the forms adjustment to the plate have changed (and usually the 2nd form will be the most noticeable) this would indicate that the roller hangers are in need of repair.

Q: I have a Speedmaster SM 74 with IR dryer. What temperature is recommended? Also would it be different for QM 46? We use a 22 micron spray powder.
A: Try starting at a point between 90 and 105 degrees depending on how thick the paper is. There are several variables but that is a good starting point. It is the same with QM 46.

Q: I am dealing with sheet mis-registration and I believe it is caused by static. I spoke with a tech the other day and he recommended using Bounce on the feed board. Is this the best option? Where should I place the Bounce strips on the feed board?
A: Depending on the press you have, you can tape fabric softener sheets to the feed board tail edge only. The printed sheets will then pass over the softener sheets, releasing the antistatic properties. However, you must be careful it does not cause mis-registration. The sheet should be fixed as far from the head stops as possible.

Q: We have a Printmaster 52 2 colors and also a SM 52 two colors, we are looking for a CTP system, but want to know the advantages between the Quicksetter 400 and the Prosetter 52.
A: The Quicksetter 400E is a CtP designed for the GTO 52 format. The PM 52 and SM 52 are larger plates sizes. The Prosetter P52 is a perfect fit for the PM 52 and SM 52. The Quicksetter is a polyester plate CtP device that is rated up to 175 line with run lengths of up to 20,000, whereas the Prosetter P52 is a very high quality, metal plate CtP rated up to 300 lines per inch, Hybrid and FM screening-capable and up to 350,000 run lengths. The Prosetter P52 can have internal punches, is the only violet CtP with Temperature Compensation, can be upgrade to various levels of automation and even to a larger 4 up format, the Prosetter P74.

Q: In our efforts to go green, we have started using Ecolo-Clean 35 on our PM-46's and would like to try it on our PM-74-4, but I am wondering if the heavier viscosity of the solvent will be a problem for the autowash or blanket wash systems?
A: You may have to change the wash up programs for rollers and blankets. The new BIO washes evaporate much more slowly than conventional washes. However, with a little experimentation they will work fine. For the first round of trials, try these settings:
H2O Wash H20 Wash H20
11 19 13 9 11
20% 30% 10% 10% 10%

Q: When running my QM 46-1 the water bottle locks up and the water pan goes dry. What is causing this annoying problem?
A: The reason for your problem is most likely that the valve does not open up completely and does not allow the water to flow correctly.

We would recommend a new water bottle cap; they can wear out after a while.

Q: On a 1996 Polar 66 trimmer. Recently I have been getting a "Knife at BDC, time interrupted" message on every cut. Through the years I have noticed that the knob for knife changing has lost some resistance. As a result it would eventually drift from the far clockwise position and I would get the same message as above, turn the knob back and it was fine. Now it's constant.

Is something worn in this valve? Hydraulic fluids are full with no leaks.
A: The message “484 Knife at BDC Time interrupted” means that the knife was released to move to the up position before the bottom dead center switch was met. This can happen from releasing the cut buttons too soon as well as having the knife go too deep into the cut stick. It should have nothing to do with the valve for knife change. The valve for knife change will keep the knife from TDC or top dead center.

Please contact our technical help desk at 800.437.7388 if you should have additional questions.

Q: I have an SM 52 A3 four colour machine and a GTO Z two colour and a GTO one colour machine. Is there a UV coating component or accessories that can be added to any of these machines to do UV printing?
A: All presses that are used for UV printing have to be factory prepared (in printing units, coating units and delivery) to withstand the more aggressive press chemistry that usually goes along with the UV printing process. The UV preparation can only be done practically in the factory when you order the press – it includes UV rollers, UV conform grippers, special prep for wash-up devices etc. If your presses are not factory UV prepared they are not approved for inline UV printing.

Both the Printmaster GTO 52 and the Speedmaster SM 52 presses can be UV prepared - and then be used for inline UV printing. However, a Heidelberg coating unit for UV is only available for the SM 52. Curing solutions for the UV dryers are available 3rd party manufacturers.

Q: I am having trouble with ink "piling" on the water metering rollers on a GTO-5 with DDS dampening, is this an ink/fountain solution issue or a roller adjustment?
A: Ink piling is normally an ink/dampening solution issue, where the ink is not able to withstand the strength of the fountain solution, either due to the mixture ratio or the type of solution altogether.

If it is the same solution you run normally, you most likely have a contamination issue that can be taken care of by washing the press with HOT WATER AND WHITE VINEGAR, (do not use a chemical deglaze or the like, as it is very hard on the rollers). The hot water will chase out the water based contaminates and the vinegar will chase the mineral deposits out of the rollers.

It may be necessary to do this several times to get the problem to go away, and it should be done on a weekly basis afterwards to prevent further contamination problems.

Q: I am running an old MO-4VP at a university in house.

At this time of year like everyone we fight with fan out on any size sheet of text and offset. The question I have is if there is anything other than sealing every nook and cranny in the building to prevent this? They use two dedicated a/c, heating and humidifying/dehumidifying units, but they seem to do little to help this problem.

Any advice would be welcome.
A: Yes, paper conditioning is the issue, but some additional questions are relevant: how old is the paper, when was it delivered, was it cut down at the correct grain If the paper was cut and not covered with plastic to keep in the moisture it will shrink and then stretch when printed, and unit 1&2 may not fit.

If the print jobs are not covered after printing and the backup does not fit it may be due to running the dryer too high causing the sheet to shrink after drying.

In any case, the paper should always be covered this time of year to prevent dehydration. The paper companies will normally provide plastic load covers to help prevent this between passes, especially if it is overnight between passes.

Q: We have just recently purchased a Heidelberg Quicksetter and need to know how to send spot colors {2/C} to the Quicksetter.

We are set up from installation to send 4/color, 1/color, and positives for silkscreen. Jobs we are trying to send as spot color are in pdf and we are using Dell PC
A: In order to print a two-color job there are two important steps that need to be followed when creating a PDF file.

All the colors in the job must be defined as the desired spot colors. This is done in the application the job is being created in (such as Quark or InDesign). The PS or PDF file should be output using the In-RIP Separations or Device N settings from the application (Quark or In Design). Once you have a properly created a PDF file the RIP will be able to separate it to the correct colors/separations.

A properly created PDF file (with 2 colors) will open in Acrobat as a composite file. In this format the on screen view will look like the final printed piece.

In Acrobat 8 you can see a preview of the separations by clicking the Advanced>Print Production>Output Preview menu. Here you can see the colors in the job and select/deselect colors to preview it.

Q: I have a PM 52 with Alcolor. We installed new rollers, and seem to be having a lot of water problems: is running too dry down the center of the plate.

Also, the intermediate roller does not want to carry ink. We have set ALL rollers to SPECS. Any suggestions?
A: Check to see if the rollers are the same type that were in the press previously – i.e. alcohol free, or crowned for alcohol? It sounds as if you have crowned rollers which are meant for alcohol, and you are running alcohol free. If you re-install the old rollers, does the press run better?

I suggest you check with who you purchased the rollers from, find out what type roller you were sold and that it is the correct roller for your application.

Q: I have a Quickmaster 46-1. I am getting scratching marks down the plate that I can't seem to stop. I have checked the water form roller and found the bearings were collapsing and replaced them, but I am still having a problem. What do you suggest?
A: Depending on the age of the machine, plate scratches might be caused by two things, the plate processor or the plate loading guides on the press.

Please check the plate guides on the press as well as the guides in the processor for sharp edges or build-up. In extreme cases worn guides with sharp edges might leave scratches.

Q: I have heard about SF 22 which I'm informed will clean both the blanket and the impression cylinder, is this correct? On our press this seems to do nothing.

Is there a listing of all the SF numbers?
A: When SF 22 (“Impression cylinder wash-up”) is selected, the blanket cylinder is thrown on the impression cylinder during the next wash-up procedure, and included in the wash-up. The selection always refers to the next wash-up procedure only! Afterwards, SF 22 (“Impression cylinder wash-up”) is deselected.

Please see a list of all customer accessible SF functions below. All current presses have all functions – however, the functionalities were added over time, so some functions might not be available on earlier presses. For further information please refer to the operator handbook.

Q: How tight should the chain be on this press (QM 46-2)?

When I inch the press around, the gripper bars are hitting the screws that hold the blowdown fans on. I'm not sure if they are hitting when the press is at speed, but there is a lot of noise and movement in the chain when running.

Which way do the adjustment bolts get turned to tighten the chain. None of this is covered in the manual.
A: The chains on the P-QM 46 are self-adjusting. If the chains are making contact they need to be replaced.

Please contact Heidelberg systemservice at 800-437-7388.

Q: I am running a QM DI Pro. I noticed over the last year I have been printing with an orange peel look on my 1st unit (black). I have to put lots of pressure to reduce the blochy look of the images. Normally I run at about a 0.05 or 0.06 on my pressure dial but now have to run at 0

to make images smooth. What is up?
A: There can be various reasons for your problem. Here a couple of suggestions:

• Check the temperature of your chiller. It might be set too cold (should be between 18-20 degree Celsius)
• Check the age of your rollers. They need to be replaced on a regular basis
• Check your roller settings - they should be as recommended in the operator manual
• The ink chemistry might have changed - check with your ink manufacturer
• Check the age and the packing of your blankets - they should be as recommended in the operator manual.

Q: I do not own a Heidelberg QM-46 Press. My major concern is the type of register control. Could you explain the type used on this small offset?
A: The Printmaster QM 46-2 has on the fly adjustments for lateral and circumferential register settings (see pictures) in both units (you can make these adjustments while the press is running). The diagonal register setting is done via a special function that positions the plate cylinder and loosens the plate. The adjustments is made in “clicks” with a provided multi purpose wrench – again a very fast adjustment.

Q: I’ve just purchased a (Heidelberg) Printmaster QM-46 and am running 12"x18" 100# text dull coated. PMS 128 (yellow) and black. Front 1/3 of sheet is solid yellow with black type on top. I put yellow in Unit 2 (nearest Feeder) and Black in Unit 1. The yellow is becoming contaminated from the black ink and the tacks are even and long (Zipset Inks). I have washed the yellow rollers thoroughly. The press run is 7,000 work and turn. Using 8 mil. polyester plates. I fault the single blanket. Any advice?
A: From the description is appears that the problem is caused by the ink tack. When running any combination of color the light ink MUST be at least 1 tack point lower than the darker ink, this way the light ink will not pull the darker ink back onto itself.

In the description it is indicated that unitack inks are used; this really only works in unitized machines, and even then the large majority of printers still use staggered tacks in their process and over print situations. With the common blanket it is important to use tack-rated inks; best results are usually achieved with the following approximate tack values: yellow 12-13, Red 14-15, blue 16-17, Black 18-19. We have seen runs as high as 10,000 sheets running Black and Yellow with no back trap contamination using the method above.

Note to readers:  In the original answer above, we focused exclusively on the topic of ink tacks, which is usually the main issue at hand. However, we didn't discuss which color to put into which unit. A sharp reader brought this to our attention (thanks Lance) so to the answer above, we add our recommended ink allocation:

Light color, low tack in Printing Unit 1 (above the delivery)
Dark color, high tack in Printing Unit 2 (above the feeder)

Q: I'm thinking of changing from metal plates to 8mil Silver Digi-Plates. Will the Printmaster 46 automatically load and eject these 8 mil polyester plates? Is there any reason to be concerned about tight registration (and trapping) between the main and second color head when using these plates?
A: 8 mil plates work very well in the PM 46. You will have to adjust the blanket packing and reset the rollers to accommodate the thicker plates. Also, be aware of different settings for the dampening system. You might also see an increase in the amount of make-ready sheets. Make sure you are using the plates with the matte back, as that minimizes the plate movement. Heidelberg also provides an 8 mil Polyester plate material called the Cristala Quickplate; if interested, please contact us at 1-888-472-9655.

Q: We have a QM 46-2, and tried on the odd occasion to print 4 color process runs, with relatively pleasing results; however we found a few issues. First we could only use an A4 sheet size, long edge into the grip. We had to use a 200 gsm board, and the register did move slightly. We were wondering, apart from the tips .pdf you have published, if there was any more information you could pass on, ie. what paper weights run the best for 4 color work? Do you have the pile pressed fully against the spring or slightly touching to keep a tight register throughout out the length of the run?
A: Not knowing the serial number and the total impressions on the machine, I will go on the premise that the machine is in average condition.

To obtain the best possible results when running 4 color process jobs on the QM 46 start with good quality paper running long grain (I would recommend 80 & 100 lb text weight minimum). This will help eliminate register problems in the tail corners (fan out). Also, if you have an IR dryer use it at approx 70% on the first pass to prevent paper shrinkage during drying, then at 90-95% on the final pass.

If the job is two-sided, run all four colors on one side before running the back side, otherwise you will have fit issues on medium-to-long runs. It is also recommended that the loads be covered with plastic if the second pass of the four color will not be run on the same day. This will help keep the moisture in the paper, which helps with fit on the second pass. The paper company's have load bags they provide to large printers for very long runs, or a small shop can use an ordinary trash bag to achieve the same result.

When setting up the feeder, always make sure the paper is firmly held to the front and side standards, and test to be sure it will feed consistently before you start the run. Once you have verified that the job is in fit and is registering to your satisfaction, DO NOT CHANGE IT DURING THE RUN. This will help to insure consistent register throughout the run.

Q: Is there an automated way to read ink dots and automatically adjust the ink keys?
A: Most prepress RIPs have the capability of generating what is called a PPF (Print Production Format) file. It is commonly referred to as a "CIP3 file." This is a file that is used to generate ink-key presets on a press and is based on the same data that is used to generate proofs and plates (or film). The PPF must be processed through an intermediate application before being sent to the press for presetting the ink keys, which analyses the ink coverage, per color and per ink zone, and calculates the physical ink key openings, which are then provided to the press. The press interprets this information and applies it automatically. The PPF can be transferred to the press either by a job memory card or directly to the press if the press is networked. The press must have remote ink control capability in order for this to work.

Most press manufacturers build the ability to read the presetting data into their presses, and sell the intermediate software that interprets the PPF. The software is usually proprietary to the press. The Heidelberg interpretation software is called Prinect Prepress Interface. Systems from Heidelberg that are capable of performing the presetting function for Speedmaster and suitably equipped Printmaster presses:

Delta RIP with CIP3 option (past generation Heidelberg RIP)
Prinect MetaDimension with CIP4 option (current generation Heidelberg RIP)

Q: We have a QM-46-2 and we’re running a 2 color letterhead on 70# Finch Fine Text. The copy is washing out like there’s too much water. We can get it to print half decent but have to run the press at 5000/hr.

If we switch the paper to almost anything else including glossy the problem goes away.

The pressman says the water roller pressure is as tight as it goes.

Do you have any suggestions?
A: This sounds like a problem of chemical contamination in the paper.

As a test try this:

  1. Run approximately 100 sheets of the paper through the press on
    impression only, (no ink or water)
  2. Wash your blanket and plate (if there was one on the press).
  3. Run the same sheets through the press normally to see if the results change.
I think you will see an improvement.

Running the paper through on impression only will help remove whatever it is on the sheet surface causing the problem.

Q: I have a 1996 Quickmaster 46-2 color. After running the 2nd unit and washing up, when going into my next job and putting the press into the production mode on the OS of the 2nd unit I have no dampener contact on the last 4 inches on my plate on the OS. I have to adjust the red screw clockwise to print clean. Is this a bad setting or a worn part? Also, both water units rock in sync with the oscillating roller - is this normal?
A: You may have to adjust your plate. This adjustment is done by means of the adjustment screws on the ends of the form roller shaft, not the Red Screw. *The Red Screw adjusts the pressure between the form and the pan roller (3mm stripe).

Items to look for if the adjustment to the plate cannot be achieved by means of the screw on the shaft:
  • Problem - The cams on the control shaft could be worn or loose
    Solution - Check for wear and the screw for tightness

  • Problem - The pins at the bottom of the water system frames could be worn or not adjusted
    Solution - The adjustment screw should be flush with frame

  • Problem - The compression springs in water system frames are worn
    Solution - Pull the adjustment screws to check springs and replace as needed

  • Problem - Frames are loose and wobbling excessively (worn bearing journals)
    Solution - You might need a new water system cpl.

  • Problem - Form roller worn
    Solution - Swap the ends to see if problem goes to opposite side
    Please note: The roller cannot be used this way because of the position of the adjustment screws to stops
* The RED screw is an adjustment screw used in setting the control stripe 3.1mm of the Dampening form roller MV.028.411 /09 to the Water pan roller MV.039.427 /02. It is possible that the self locking Helicoil is fatigued and allows free movement of the RED screw and loss of adjustment. Replacement of Helicoil required HDM: Part number 00.580.2707/ Threaded insert magazine M6x0, 75x 9 and can be ordered thru Heidelberg spare parts. As this insert requires special tools to insert, you would need to contact and request the following tool, part number # 50188.

Additionally, it would also be possible that you are experiencing bearing fatigue of dampening rollers. Please check and inspect for damage and or wear of all bearings of the Dampening system.

This answer is our response based on your input. If you have any concern on how to safely make any of these adjustments or to investigate the problem further, please contact Heidelberg systemservice 1-800-437-7388.

Q: I have Version 1.5.5 (Build 613.1) Medium format, PDF handler 2.77

Imagine the following:

4 pages of 8 1/2 by 11 (Automatic platement rule), Saddlestich binding.
Plate: SM 74, Work and Turn, sheetsize 25 by 19
Scheme: F04-01_ui_2x1, expert mode check odd columns (head-to-head)


Now, rotate page one using this method:

In the Press Sheet view, double click page one (folding sheet inspector) and double clock page one AGAIN (Page Inspector) . In placement rule for 1up, choose By user, from trim, 180.

Go back to Press Sheet view and confirm page one is rotated.


I want the rotated page to stay rotated, in other words I want it to "stick" no matter what else I do.

Bring up Job Part Instector (control-2), click on schemes, Gaps and master pages, and change something, say the vertical gutter by typing in a new number. Naturally you see the warning you are about to change a setting that another inspector has set, but click on yes. Notice that page one has rotated itself back to its default orientation.

Is there any way to rotate the page, and make it stick?
A: In Imposition mode, Signa Station will automatically adjust back to the original folding scheme if a page is rotated. Use Montage mode to avoid this behavior.

Q: Why is it that Heidelberg DI presses are not sold anymore?
A: Heidelberg USA continues to sell Quickmaster DI presses. The majority of these presses are refurbished presses. The refurbished DI presses offer an affordable and easy entry into the four color short run market. Heidelberg USA continues to support all existing Quickmaster DI users with parts, service, consumables (plates, blankets etc.), RIP upgrades as well as phone support for print technical questions and workflow questions. Heidelberg stopped manufacturing new QM DI presses because the worldwide demand for new small format presses shifted towards landscape presses with more flexible configurations (e.g. 5th color, inline coating, inline perfecting). At the same time the advent of small format CtP systems, attractive CtP-plate pricing, greater press automation and overall higher productivity changed some of the underlying assumptions that made the new QM DI presses a great success in earlier years.

Q: I have a GTO Z-52. Can a coating unit be put on this press?
A: There is a Heidelberg approved roll-on coating unit available. It is manufactured by the German company LACO.

There are some prerequisites for the press for this to work with the LACO unit. It must have the "Plus" drive - also called the "basic equipment for numbering and imprinting," which can't be retrofitted to an existing press. The "Plus" drive is necessary to drive the coating unit during the production run. Also, the interface adapter for peripheral devices (STA unit) is required - if necessary, this part can be retrofitted to an existing press. Once installed, the LACO coating unit requires an air-cooled dryer - usually these two components are sold and installed together.

Check the LACO website for images and more details:

Q: I seem to be going through a lot of wash up blades on my GTO 52, about 1 each unit every 2 months. Is there a fix for this?
A: There are two reasons that wash up blades wear quickly, the first is that they are set too tight against the oscillating roller and the second is allowing the blade to remain on the roller too long at the end of the wash up.

When setting the wash up blade, the operator needs to set the blade (on models with manual adjusting screws) just light enough to remove the ink and no more.

On models newer than Drupa 2000, the operator should check the adjustment of the stop screw on the operator and drive side for proper adjustment, (see drawing below) so that when the wash up unit is engaged it make just enough contact to remove the ink.

Q: Do you need to run different Ink Tacks when running a two color job?
A: Yes and No…… No, because if the colors on the job are not touching, then the ink tacks can be the same. Yes if you are wet trapping; then you need different ink tacks so they trap properly on the sheet of paper.

Q: Is there any way to keep the polyester plate from stretching?
A: Yes. You can turn the plate over on the back side, and use 500 grit wet and dry automotive type sandpaper to scratch the back side of the plate at a 45 degree angle to the lead edge of the plate, in both directions. Then wet the back side of the plate and load it on the cylinder……The scratches will provide pockets of air and water and cause the plate to stick to the cylinder. The only downside is that the plate will have to be taken off by hand because it sticks so well to the cylinder.

Q: If you add ink reducer to ink, will it change the color?
A: Yes. Ink chemists have formulated the ink with the correct ratios of ink pigment (color), vehicle (carrying agent), and additives for drying of the ink, so if you add anything to the ink it will weaken the strength of the other two categories, causing the ink to be light in film strength. Talk to your ink manufacture to make changes to your ink; their chemists have much more knowledge about the make up of the ink and can provide you with a solution for your needs.

Q: I'm getting a tone down the side of the printed sheet. What could be the cause?
A: There could be many reasons for this condition. The first to check are the roller adjustments in the ink train, you could have swelled rollers. The second would be to check the dampening system for adjustment, where perhaps the water system is only working on one side or the other. The third would be to check rollers to make sure they have enough ink on them to carry the water to the plate and the ink is not emulsified. There are many reasons that a tone or scum happens on a plate.
