Solutions

Diagnóstico rápido

This error occurs when the internal thermistor detects abnormal thermal readings. If your printer has been running for a long time or has experienced a recent paper jam, the sensor might have triggered a safety lockout to prevent overheating.

Solución paso a paso

  1. Power cycle: Unplug the unit for 5 minutes to allow the thermal system to cool down and clear logic errors.
  2. Check fuser: Open the rear door and ensure no paper scraps are stuck to the hot rollers.
  3. Clear paths: Remove any debris from the paper path that might be affecting the fuser sensor.
  4. Reset: Reconnect the printer and monitor the boot sequence to see if the error persists.
