Canon imageCLASS X1440P error e805-0000: Fan Failure

The Canon imageCLASS X1440P error e805-0000 is a safety warning indicating a failure in the printer's main cooling fan. This error code appears when the system detects that the fan is not rotating at the appropriate speed, preventing the dissipation of heat generated by internal components. If left unresolved, the device will lock up to prevent critical damage from overheating.

Common causes

  • 1Mechanical fan blockage due to dust buildup.
  • 2End of fan service life (bearing failure).
  • 3Faulty speed sensor (tachometer) integrated into the fan.
  • 4Power supply failure in the logic board port.

Solutions

Diagnóstico rápido

Error e805-0000 is confirmed by hearing a loud buzzing followed by total silence before the message appears. Check if the rear fan has an extreme buildup of dust blocking its natural movement.

Solución paso a paso

  1. Immediate Power-Off: Unplug the equipment to avoid heat damage.
  2. Check for Obstructions: Visually check for any paper scraps or debris blocking the rear airflow.
  3. Compressed Air Cleaning: Use compressed air to remove dust accumulated on the fan blades.
  4. Rotation Test: If the fan does not spin after cleaning, the component has failed mechanically.

Prevención y mantenimiento

Place the printer in a ventilated area with at least 15 cm of separation from walls. Perform preventive ventilation cleaning every 6 months to prevent lint and particle ingress.

Cuándo llamar a un técnico

If the error persists after cleaning the fan, the fan motor needs professional replacement. Do not attempt internal repairs if the unit is under warranty.

Frequently asked questions

This code indicates a failure in the system's cooling fan. The printer cannot guarantee a safe operating temperature and shuts down.

Yes. Overheating can permanently damage the logic board or fuser if the cooling fan is not operational.

Use genuine Canon 071 cartridges. Overheating is sometimes caused by excessive friction from third-party cartridges.

Keep the back of the printer away from walls to ensure correct airflow.
