Common causes

  • 1Fan blade obstruction due to excessive internal dust buildup.
  • 2Bearing failure in the cooling fan due to continuous usage in high-temperature environments.
  • 3Logic board failure in the sensor circuitry monitoring fan rotation.
  • 4Foreign objects trapped inside the chassis interfering with blade movement.

Solutions

Diagnóstico rápido

The error E805 appears as a persistent system stall. You can confirm it is an E805 by listening for the lack of fan startup noise, which should occur within seconds of powering the device on.

Solución paso a paso

  1. Ventilation check: Inspect the side vents to ensure they are not blocked by paper or debris, allowing proper airflow.
  2. Hard reset: Unplug the printer and hold the power button for 30 seconds to discharge internal circuits.
  3. Test run: Reconnect the device to a stable power source and power it on to see if the fan engages correctly.

Prevención y mantenimiento

Place the printer in a well-ventilated, dust-free location. Avoid printing continuously for long periods in hot environments. Using original supplies helps keep the printer interior clean, minimizing the risk of dust-related mechanical failures in the cooling fans.

Cuándo llamar a un técnico

If the error persists after a hard reset, the cooling fan motor has likely failed. Professional repair is required to replace the motor, as improper handling during disassembly can break plastic latching components or disturb sensitive wiring.

Frequently asked questions

Error E805 occurs when the system detects that the internal cooling fan is not spinning at the required speed or has been physically obstructed.

Yes, the fan protects critical electronics from overheating. Ignoring the code can lead to permanent damage of the logic board.

Original toners reduce dust contamination inside the printer, preventing particles from interfering with sensitive components like the cooling fan.

Clean the exterior vents with compressed air every 6 months to ensure steady airflow and prevent error codes.
