Right side of label faded or blank after replacing printhead
I replaced my printhead and now the right side of the label is blank or faded. I have tightened the printhead assembly as much as possible but still no luck. If I put a slight amount of pressure on the printhead when printing and it works fine.
Re: Right side of label faded or blank after replacing...
Things to check:
1. Move the pressure arm further towards the outside of the printhead. Adjust if needed using only the minimum pressure required in order to achieve uniform print quality.
2. Inspect the printhead to ensure it has properly engaged the alignment pins. I have had after-market printheads that did not line up correctly and required "surgery" to make them properly seat on the mounting pins.
3. Check for worn platen roller bearings. If they're are sufficiently worn, one side of the platen roller will be slightly lower than the other.
4. Consider replacing the platen roller. They do wear out and require replacement. Zebra part number 40038M IIRC.
5. Check the printhead parallelism adjustment. The procedure is in the maintenance manual.

One of two
1. If the printing stops with clear stopping edge, then the PRINT WIDTH
setting has been changed from the default full width setting of 104mm.
Check this by pressing MENU and then the NEXT button until you see a setting for MAX WIDTH. It should be set to full width of 104mm. Anything less will stop printing beyond whatever the setting is. Change it back to the full width setting.
2. If the printing stops by fading away to the right side, then that is
caused by a pressure imbalance across the printhead. There is more
pressure on the left side than the right side. There are two toggles
that press down on the printhead and the pressure can be adjusted by moving the right toggle to the right so that more pressure falls on that side of the printhead.
So the left side is blank ? Usually caused by an imbalance across the printhead. Check the toggle pressure on the left side. Each toggle has a dial on top for adjusting the down pressure. Probably less pressure on the left than the right. Quick test would be to use your finger to put some down pressure on the left side of the printhead while printing. If the print is there, you have your answer. If still no printing, then something else is happening.
One of two situations exists:
1. If the printing stops with clear stopping edge, then the PRINT WIDTH setting has been changed from the default full width setting of 104mm.
Best way to check this is to take your tallest and widest label and print out a configuration label. This is done by turning off the priner, pressing the CANCEL key and holding while turning on the printer. Release the button when the calibrate led turns off. A config label will print and you can check the setting for PRINT WIDTH.
2. If the printing stops by fading away to the right side, then that is caused by a pressure imbalance across the printhead. There is more pressure on the left side than the right side. There are two toggles the press down on the printhead and the pressure can be adjusted on each by turning the knob on top. Readjust the right side until printing returns across the label.
Not too sure what you mean here. If the print on the left side is Ok and faded on the right side, then the position of the printhead pressure toggle may need to be adjusted. Make sure it is positioned over the center of your label.
It's very possible the printhead wasn't installed correctly. It's pretty easy to get it wrong, as there are two pins on the latched printhead bracket that have to fit into two holes on the printhead itself. You have to get the alignment of these pins and holes just perfect before you tighten the screw. You have to make sure the aluminum plate on the printhead is sitting flat against the printer's printhead bracket before you turn the screw on top of the bracket.
To solve the faded prints you need to clean the printhead twice by going to the software and click the "?" mark icon on the upper right corner of the software window and then under General Links select Maintenance then choose Clean Printhead - do it at least thrice to unclog the printhead system. Then try making prints... If still cannot solve call Kodak Technical Support.
There are two possible solutions to this common problem.
1) The Cyan cartridge may not be in 100% of the way. If the handle of the Cyan cartridge prutrudes even slightly, it can obstruct the printhead for the black developer. Remove and reinstall the Cyan cartridge and test.
2) The printhead is dirty, with some toner spillage on the printhead. All new imaging drums also include a new cleaning pad for the cleaning wand.
The cleaning wand is designed to clean toner off of the printhead. you can see this in your printer manual, but basically, just open the front cover, pull the the blue handle on the right side forward ( this opens the access cover for the cleaning wand on the right side of the printer ).
gently pull the cleaning wand out ALL THE WAY, then slide it back in ALL THE WAY. do this several times.
The cleaning wand is intended to travel across the print head in only one direction, which is why you should make sure that it is pulled all the way out.
One of these two solutions should fix your problem. If the problem is resolved, but then reappears after a short time, then you have a defective developer that is leaking toner on the print head. The color of the defective developer can be determined by the color of the cleaning pad after cleaning the printhead as discribed above.
I would say the roller isn't the problem. I had the same problem on many Zebra printers, but often the calibration helped. Then it could do, when printing
task label is for larger/longer than the label size is set in the printer system
(conflict of software with printer settings after calibration). It could be set too down to bottom in Y axis. Or
it could be in the software settings - as action after print - not sure. Try to open the printer queue while the label is printed and check if the label has proper number of pages or there's 1 page more. If it is the right number - then the problem is on printer side (recalibrate, reflash it). If the number is about 1 higher, the problem is with settings of the label size (barcode software, printer settings) or action after print on PC side.
