Common causes

  • 1Faulty thermistor that fails to correctly read fuser temperature.
  • 2Burnt-out fuser heating lamp due to reaching its end-of-life.
  • 3Electrical supply issues preventing the fuser from heating properly.
  • 4Debris or paper remnants blocking the temperature sensors.

Solutions

Diagnóstico rápido

Error C-441 appears on the touch panel and stops all printing tasks. If the error continues after a reboot, it usually points to a physical problem with the thermistors or the heating lamp within the fuser assembly, meaning the machine cannot complete the initial self-test.

Solución paso a paso

  1. Power cycle the device: Turn off the printer via the main switch and disconnect the power cable for at least 10 minutes.
  2. Inspect the fuser unit: Look for paper jams or physical obstructions near the fuser assembly.
  3. Restart the system: Reconnect the power and turn the machine back on to check if the C-441 code clears.

Prevención y mantenimiento

To avoid thermal errors, ensure the machine is plugged into a stable voltage regulator. Regularly clean the internal rollers to prevent toner build-up. Using only original consumables helps keep the fuser assembly in top working condition.

Cuándo llamar a un técnico

If the error persists after a reboot, there is likely a faulty thermistor or a burnt-out fuser lamp. Contact a professional service technician, as working on the fuser assembly requires specialized tools and technical expertise to avoid permanent damage.
