    Possible cause of the error


    This can happen if the lever on the cover open sensor is knocked off the switch assembly.

    What to do


    Try to determine if there is a hardware fault. To do this:



      1. Disconnect the power cable and the USB cable.

      2. Remove the cartridges from the printer.

      3. Check that the power cable is plugged directly into a wall socket.

      4. Reconnect the power cable.

      5. If the error persists, please contact Lexmark Technical Support for further instructions.

    Contacting Lexmark


    Please contact Lexmark Technical Support for additional assistance. NOTE: When calling for service, you will need to know your printer model type and serial number.

Lexmark x5250 flashing green power light


The flashing light could indicate either a communication problem between one of your cartridges and the printer, a short in one of the cartridges, paper jam or the cartridge carrier has stalled. Please follow the steps below to fix the problem:

  1. Remove the sheets of paper from the feeder. Make sure there are no foreign objects or debris in the feeder.
  2. Open the printer cover and remove both the cartridges.
  3. While the cover is open, ensure there are no paper jams and the cartridge carrier is free from obstructions.
  4. Close the printer cover.
  5. Re-brick your printer. Pull out the power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds.
  6. When the printer turns on, reinsert one cartridge first.
  7. Close the printer cover and check the light status.
  8. If light on printer is normal, open the printer cover and reinsert the other cartridge. Check the light status.
  9. Replace whichever cartridge is causing the light to flash with a new cartridge. You can also try to insert a different known working cartridge to determine if the other is faulty.
  10. Load some paper. Try to print a document again to verify that the problem is fixed.

I changed the ink in my Lexmark 3400 printer and I keep getting an error message "cover open" and it's not open. I tried everything....unloading the software then reloading the software, shutting it off...


The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.

This can happen if the lever on the cover open sensor is knocked off the switch assembly.

Lexmark X125 not printing at all.


Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
