Solutions

Quick Diagnosis

The C-5351 error occurs when the printer senses the fuser cooling fan is not reporting the correct speed. If the machine halts during start-up or heavy print jobs, it confirms a cooling fault.

Step-by-Step Solution

  1. Immediately power off via the main switch.
  2. Clean external vents to remove any dust blocking airflow.
  3. Do not attempt to restart until the machine is fully cool.
  4. Call support to replace the failed fan module.

Prevention and Maintenance

Regularly clean the external dust filters. Always position the printer at least 30cm away from walls to ensure constant fresh air intake.

When to Call a Technician

Since this involves critical cooling of a heating unit, you must schedule a technician to replace the internal fan system. This is not a user-serviceable repair.
