93x Printhead Error
Each printhead error has its own error code number. The error codes and their respective meanings are listed below, together with some actions you can take to resolve the problem.
ALL printhead errors:
If this is the first time the error has occurred, try turning the printer off and on.
Let it sit turned off for at least 20 seconds before powering it back on.
If powering off and on the printer clears the error, please continue using the printer but watch it to see if any printhead errors return.
If your printer continues to display a Printhead Error message, make sure it is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer. This can trigger a printhead error even if the printer has worked on this surge device for months.
If the printer continues to post a 930 Printhead Error, it thinks the wrong printhead unit is installed.
If the printer was recently serviced, make sure the correct parts were used. This is especially true if the parts replaced were either the printhead unit or the printer's engine/system board. It is in one of these two parts that the printer is detecting the problem. Note: If you are the person repairing such a printer, please be aware that parts from different, though similar, printer models may not be compatible with this printer. Also make sure to check the laser cable going from the printer's engine board to the printhead unit, as it reads that signal.
If the printer was not recently serviced before this error occurred and powering the printer off and on does not help, the printhead unit and possibly the laser cable or the engine/system board to this printer may need to be replaced.
If the printer continues to post a 931 Printhead Error, it thinks there is an error in the signal going to the laser or the Hsync part of the printhead assembly.
If the printer continues to post a 932 Printhead Error, it thinks there is an Hsync error occurring in the printhead assembly.
If the printer continues to post a 933 Printhead Error, it thinks there is a failure in either the Hsync signal or with the mirror motor unit of the printhead.
If the printer continues to post a 934 Printhead Error, it thinks there is a "lock" failure with the mirror motor assembly within the printhead assembly.
If the printer continues to post a 935 Printhead Error, it thinks the mirror motor unit within the printhead unit cannot reach its operating speed.
If powering the printer off and on does not clear any of these errors and it is already connected directly to the wall, your printer may require service. It could have a defective printhead unit or there might be a problem with the engine board or one of the printhead cables. Note: If you are the person repairing such a printer, check all of the cables going from the printer's engine board to the printhead unit for any damage. Also check the continuity across these cables.

I had the same problem, I changed the photo conductor and it was ok.
I disassemble that part, all the bottom, I clean it with air, they were a lot of ink in, and after that, it works correctly.
Be careful not to touch the photo conductor with your finger, and avoid having strong light on it

994 Service Engine Error on a Lexmark C510 ID: ENUS21233 If your printer is unable to move the photodeveloper belt to the correct position during printing, a 994 error will occur. However, it may simply be the case that the photodeveloper is either contaminated with excess toner or improperly installed. To test for and resolve this issue, please do the following:

The error 995 refers to a problem with the High Voltage Power Supply. This could mean three things one is that the Photodeveloper cartridge is damaged and needs to be replaced. The second one could be a problem with the High Volt Power Supply not providing enough charge to the Photodev. The third thing could be that the Engine Board is damaged causing the error in the display. You can try to reset the Photodev by pulling it out and the seating it back in the printer.

A Printhead Error message indicates that the printhead (laser scanner) unit inside the printer is not working correctly.
NOTE: On the E250d(n) models, all service errors are signified by the flashing of all of the lights. To determine if this is a printhead error, quickly double-press the button to see the secondary code. If the !, , and lights are the only ones blinking, a printhead or a motor failure is indicated. For more information on deciphering the error lights, click here (PDF file, 255KB).
Step Action 1 If this is the first time you have seen the error, turn the printer off. 2 Leave the printer powered off for 10 seconds or more before turning it back on. This gives the printer a chance to reset. 3
Power the printer back on. If it goes to the Ready state, try printing again. If the error does not return, continue using the printer. 4
If the printhead error returns when the printer is powered on or when you try to print again, follow the suggestions below.
If this is an intermittent error, you may want to check how the printer is plugged into the wall.
Make sure the printer is plugged straight into the wall and not through a surge device or power strip. Please try this even if the printer previously worked correctly with this surge device. Power strips and uninterrupted power supplies can cause a low amperage problem, which can trigger a false printhead error.
You may also want to try plugging the printer into a different wall outlet to see if the printhead error continues. This will eliminate the power source as a possible cause of the issue.
If the error does not clear, the printer will probably require service to correct the issue. Please contact Lexmark Technical Support or a local authorized servicer for assistance.
When calling Lexmark Technical Support for service, please be prepared to describe the problem you are experiencing or the error message on the display. You will also need to provide your printer's model type and serial number. This information can be found on a label on the inside of the front cover of the printer.
Please call from near the printer in case the technician asks you to perform a task involving the printer.
Have a nice day and do not forget to rate please...!
