  • All lights flashing; 
  • Error light on

What the error means:

A Printhead Error message indicates that the printhead (laser scanner) unit inside the printer is not working correctly.

For Lexmark E250d(n): 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.

How to clear the error:
  • If this is the first time you have seen the error, turn the printer off.
  • Leave the printer powered off for 10 seconds or more before turning it back on. This gives the printer a chance to reset.
  • 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.
  • If the printhead error returns when the printer is powered on or when you try to print again: check the power source the printer is plugged into. 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 continues: the printer will probably require service to correct the issue. Contact Lexmark Technical Support or a local authorized servicer for assistance.

Scanner laser parts list:

Hi Jeff,

No, you'll have to replace the printhead (or scanner laser)
