Solutions

Diagnóstico rápido

This error appears when the printer cannot maintain the target temperature. If the screen displays C460, the hardware prevents further operation until the error is acknowledged and the thermal system is verified.

Solución paso a paso

  1. Cool down: Turn off the power and wait at least 15 minutes to allow the fuser to cool down.
  2. Inspection: Open the side panel to visually inspect the fuser for paper debris or toner buildup.
  3. Reset: Enter service mode (hold 0+8 while booting) and run the fuser error clear command (usually code 400).
  4. Reboot: Cycle the power to check if the error is resolved.

Prevención y mantenimiento

Avoid using overly heavy media which can stress the fuser. Regularly clean the paper path and adhere to the scheduled roller pressure maintenance intervals to prevent thermal irregularities.

Cuándo llamar a un técnico

If the error code persists after a service mode reset, the thermistor likely needs replacement or the main power board has a faulty fuser sensing circuit.
