  • 1Fuser heating lamp failure.
  • 2Dirty or miscalibrated thermistor.
  • 3Severe fluctuations in the power grid.
  • 4Thermal fuse tripped due to overheating.

Solutions

Diagnóstico rápido

The C440 can be temporary if the building's voltage dropped. If it occurs after long dormancy, the heat lamp is likely worn out.

Solución paso a paso

  1. Power Off Cycle: Let the device rest for 15 minutes to stabilize thermal levels.
  2. Visual Inspection: Open the panel and scan for paper bits obstructing the thermal roller.
  3. Sensor Check: Verify that the thermistor is correctly positioned.
  4. Reset: Reboot and wait for the pre-heating cycle.

Prevención y mantenimiento

Cleaning vents ensures uniform temperature. Using quality paper avoids leaving particles on rollers that interfere with sensor accuracy.

Cuándo llamar a un técnico

If the C440 message persists constantly after restarting, the heating lamp is likely burnt out and requires professional replacement.
