The Canon imageRUNNER ADVANCE DX C3826i error E805 signals a cooling fan malfunction, requiring immediate attention to prevent overheating. As a security measure, the printer stops operations when the internal fan does not reach the expected rotation speed, often due to physical obstructions or mechanical failure.
Common causes
- 1Excessive paper dust blocking fan blades.
- 2Mechanical wear in the fan motor bearings.
- 3Failure in the fan speed sensor.
- 4External obstructions blocking airflow.
Solutions
