Common causes

  • 1Fan motor failure: The motor has worn out electrically.
  • 2Obstruction: Dust and debris limit airflow.
  • 3Physical blockage: Foreign items stopping fan blades.
  • 4Control circuit fault: Controller logic failing to power the fan.

Solutions

Diagnostic Check

The E805-0000 code appears if the fan speed falls below the required threshold. Check if the printer vents are covered or if there is excessive internal dust preventing the fan from spinning.

Step-by-step Solution

  1. Visual check: Ensure no external obstructions block the rear or side vents.
  2. Air cleaning: Blow out the vents with compressed air to clear internal dust.
  3. Restart: Cycle the power to check if the motor can overcome initial friction.

Maintenance and Prevention

Regular 3-month air intake cleaning is recommended. Always maintain 6 inches of clearance from surrounding walls to allow the fan to function correctly.

When to Call a Technician

If the fan makes grinding noises or fails to spin after cleaning, the motor assembly is faulty and needs replacing by a technician.
