9xx.xx error code; Not enough CPU resources;


What you will see

The printer posts a 902.86 Service Engine Software error. The error might occur even when the machine is idle.


Possible cause

This issue might occur if the printer’s engine firmware does not have enough CPU resources, something most likely induced by factors outside the printer (environmental). The following are possible root causes that may result in a 902.86 symptom.

  • Network Configuration / Speed
  • Dirty or unregulated power source
  • Poor behaving solution / server
  • Security Scans directed at the device
  • Bad LVPS
  • Bad cables in wiring closet
  • Bad Network Cable connected device
  • Bad Fax Modem / Phone Line
  • Bad Operator Panel Connection


Suggested remedy

If this is the first time that you have encountered this error, see whether you will be able to clear it by performing a power-on reset (POR).

  1. Power off the printer.
  2. Wait for about ten seconds.
  3. Power the printer back on.

Should the error clear, continue using the printer and observe whether the error returns. Should the error return or if it appears intermittently, isolate the possible cause of the issue by disconnecting:

  • The network cable
  • USB cable
  • Fax line

Should issue persist even without the data lines connected, then it could be caused by failing parts inside the printer. If this is the case, please contact Lexmark Technical Support to set up service for the printer.
