Solutions

Diagnóstico rápido

If the printer stops working and displays this code, the thermal sensor is likely not detecting the correct heat in the fuser.

Solución paso a paso

  1. Power Off: Unplug the power cord for at least 10 minutes.
  2. Visual Inspection: Check for paper fragments near the rear fuser area.
  3. Restart: Power on the unit and check if the code clears after warming up.
  4. Power stability: Ensure there are no voltage fluctuations at the wall outlet.

Prevención y mantenimiento

Perform monthly cleaning of the output rollers. Avoid using heavy cardstock or labels unless certified, as these trap heat and cause premature fuser damage. Using genuine toner keeps internal rollers cleaner.

Cuándo llamar a un técnico

If the error persists after a full power cycle, the thermistor or fuser lamp is likely faulty and requires professional replacement.
