If the error persists after checking the main front door, verify the rear fuser cover as well. A small piece of paper can easily cause the sensor to remain 'open'.

  1. Open and close the front door firmly.
  2. Check the rear cover to ensure it clicks closed.
  3. Clear any debris obstructing the sensor.
  4. Power cycle the printer to reset the safety loop.

Prevention and Maintenance

Always check for toner cartridge alignment before closing the door. If the toner is slightly misaligned, the door will not lock correctly.
