  1. External Cleaning: Use compressed air on the rear/side vents to dislodge dust.
  2. Visual Check: Examine if any external obstruction is blocking the blades from turning.
  3. System Cycle: Power cycle the device after ensuring the fan path is clear.

Prevention and Maintenance

Do not push the printer against walls. Ensure at least 15cm of clearance behind the unit. Dust out the air intakes every few months.

When to Call a Technician

If the fan is clear of dust but still won't spin, an internal motor or circuit failure is present, necessitating professional repair.
