Quick Diagnosis

The error 900.00 is a standard Lexmark error code for a software fault. Check if the error appears only when connected to the office network, as this may point towards a conflicting data packet being sent to the printer.

  2. Disconnect all external interfaces (Ethernet/USB).
  3. Power on the unit and check for stability.
  4. Flash the firmware if the unit successfully boots to the menu, using the official Lexmark utility.

Prevention and Maintenance

Use a surge protector to prevent unstable current from affecting the logic board. Never turn off the printer while it is processing a firmware update. Utilizing high-quality original toners also reduces the risk of communication errors with the system board.
