Fix Canon LBP6230dw Error E805: Fan Fault Guide

The E805 error code on the Canon imageCLASS LBP6230dw indicates a fault in the cooling fan motor. This fan is critical for exhausting the heat generated by the fuser during printing. If the internal sensor detects that the fan is not spinning at the required minimum RPM, the printer enters a safety lock mode to prevent damage from extreme heat.

Common causes

  • 1Fan motor failure: Natural wear or short-circuit in the DC motor.
  • 2Dust buildup: Excessive dirt increasing shaft friction and preventing free rotation.
  • 3External obstruction: Foreign objects or stray cables blocking fan blade rotation.
  • 4RPM sensor failure: Internal Hall sensor failing to report fan speed to the logic board.

Solutions

Diagnóstico rápido

The E805 error is identified if the fan does not emit its characteristic hum upon startup or if the printer shuts down abruptly after a few seconds. Confirmation is achieved by checking for airflow at the rear exhaust port of the printer.

Solución paso a paso

  1. Turn off and unplug the unit to ensure safe handling.
  2. Clean the vents using a dry cloth or compressed air to ensure no dust buildup is impeding the fan blades.
  3. Check for obstructions that may be physically blocking the fan blades from the exterior.
  4. Test the startup in a room with a moderate temperature (below 25°C) to allow the system to boot without excessive thermal load.

Prevención y mantenimiento

Maintain at least 15 cm of clearance around all ventilation vents. Avoid using the printer in dusty environments, as this accelerates fan bearing degradation.

Cuándo llamar a un técnico

If the fan is physically jammed or does not rotate despite clean vents, the fan motor has likely failed. Replacing this component requires internal chassis access and should be performed by a professional.

Steps to follow

  1. 1

    Power Off

    Disconnect the power cord and wait 5 minutes for the electronics to cool.

  2. 2

    Vent Cleaning

    Use a compressed air can to clean the ventilation slits and remove debris.

  3. 3

    Check for any small objects obstructing the fan blades through the rear slits.

  4. 4

    Operation Test

    Power the printer on and verify if the fan starts spinning silently.

Frequently asked questions

It is not safe. Without proper ventilation, internal components can overheat, leading to permanent damage to the fuser or logic board.

Regularly cleaning the vents every 6 months is the best way to prevent dust from entering the fan mechanism.

No, this error is isolated to the cooling system and is independent of the toner cartridge status.

The fan part is inexpensive, but labor costs will apply for the technician to disassemble the printer chassis.
