Solutions

Diagnóstico rápido

C3100 appears if the fan revolution sensor detects the fan has stopped. If you hear weird noises or feel no airflow at the back of the machine, the fan might be jammed.

Solución paso a paso

  1. De-energize: Turn off the printer and disconnect the power cord.
  2. Access and Clean: Locate the fan grille on the rear. Use compressed air to clear accumulated dust preventing the blades from turning.
  3. Physical check: Ensure no debris is physically impeding the blades (perform this while unplugged).
  4. Reset: Power on and verify if the system recognizes the fan's rotation.

Prevención y mantenimiento

Keep the printer's surroundings clean. Avoid dusty environments, as debris easily clogs fan blades, reducing cooling efficiency. Annual cleaning of internal components is recommended for heavy users.

Cuándo llamar a un técnico

If the error persists after external cleaning and rebooting, the fan motor may be burnt out or the mainboard control signal is missing, requiring professional repair.
