Document ID:SO3997

Usergroup :External


Printer not working; Error light; All lights on; All LED solid on boot-up


What you will see

All the lights on the printer operator panel will come on, and stay on, whenever you power it up. The printer will be unresponsive. Any attempt to print will fail.

Recommended action

IMPORTANT! The solution in this article applies only if the lights are on solid. If all the lights are flashing, a service error that requires user intervention is indicated. Please contact Lexmark Technical Support for assistance. See 'Contacting Lexmark' below for contact information.  
  1If the printer exhibits this condition either when it is powered on or printing, switch off the printer. Let it sit, powered off, for 30 seconds to one minute. NOTE: While the printer is off, please clear any unfinished print jobs remaining on the computer or in the software/network queue.
Power the printer back on. If it powers up to the ready state, try printing again.

  • If the issue occurs again on power-up or whenever you try to print, the printer will require service to correct the issue. Please contact Lexmark Technical Support or an authorized service center for assistance. See 'Contacting Lexmark' below.

  • If the printer prints successfully, this may have been an isolated incident. Continue using the printer, but observe it closely over the next couple of weeks to see if the issue returns. If the issue does return, power off and on the printer to clear the issue. This is just a temporary measure, however, and the printer may require service to correct the issue permanently. Contact Lexmark Technical Support or an authorized service center for assistance. See 'Contacting Lexmark' below.
