Quick Diagnosis

If the machine makes metallic noises or the error occurs instantly on boot, the heat roller or lamp may be physically damaged. If it appears after a paper jam, a reset is often sufficient.

Step-by-Step Solution

  1. Service Mode: Press [Reset], [1], [0], [7], and hold [C] until the panel shifts.
  2. Execute Reset: Navigate to SP 5810, select the SC counter, and hit Execute.
  3. Reboot: Turn the machine off and on to clear the error from the buffer.

Prevention and Maintenance

Replace the fuser unit if it exceeds 100,000 prints. Clean the glass weekly to prevent debris from falling into the fuser area.

When to Call a Technician

If the error returns after a reset, the heating lamp or thermistor is burnt out and requires professional replacement.
