The problem could be due to the cartridge/s in the carrier or the carrier has stalled. Please follow the steps below to fix the problem:

1. Open the printer cover and remove the cartridges.
2. Check the cartridge area for any debris or foreign objects blocking the cartridge carrier. Check the encoder strip (transparent strip behind the carrier) and make sure it has gotten unseated from its position.
3. If the cartridge is clear and looks normal, close the printer cover.
4. Unplug and re-plug the printer into the power source to reset it.
5. When the printer turns on, check for any error. If "alignment" error appears again, please contact Lexmark Technical Support Center for additional assistance. If no error appears, reinsert one cartridge first.
6. Close the printer cover and check for errors.
7. If no error appears, reinsert the other cartridge.
8. Replace whichever cartridge is causing the error to appear. It could be a faulty cartridge. You may also try to insert a different known working cartridge to determine if your other cartridge is faulty.

If problem continues, please contact Lexmark Technical Support Center for additional assistance.

59.6K is a problem with the black image drum.
Take the black cartridge out of the printer. Shake it, reinstall it. Power cycle the printer. If the error comes back, remove the black image drum and reseat it. The image drums(one for each color) sit below the toner cartridges.
If the error still comes back a tech is going to have to look at the printer.

Check the toner bottle. power off the machine, remove the bottle, power on the machine when it ask for toner install the bottle correctly. if the code comes back have technician look at. KonicaMinolta Tech.

This is a power supply issue. You will probably need to replace your power supply on the machine

if its printing junk prints please reinstall the printer driver and check


if its printer unclear print please replace the ink and check

Check the manual for the definition of the error message.
then you will know what to ask about.

Turn the printer off and then back on. Does it go to the ready state? or does it come up and error? If the error only comes up when asking the printer to print then the printer probably has a worn paper pickup roller. You can take the old roller out and rotate the rubber tyre a little.
