Common causes

  • 1Severe paper jam in fuser/transfer areas.
  • 2Worn-out motor gear train.
  • 3Defective drum unit seizing the rotation.
  • 4Electrical malfunction in the motor speed controller.

Solutions

Quick Diagnosis

If this error appears, listen closely: a humming sound or loud clicking usually indicates a jammed gear train or stalled motor.

Step-by-step Solution

  1. Power Off: Disconnect immediately to protect the circuit.
  2. Inspect: Check for any debris around the fuser area.
  3. Restart: Re-seat components and attempt to power back up.

Prevention and Maintenance

Do not overload input trays. Regularly clean residue build-up to reduce strain on the motor.

When to call a technician

If no jam is found, the internal main motor assembly has likely reached its end of service.

Frequently asked questions

It means the main motor cannot rotate, usually due to a mechanical jam.

Yes, forcing it can damage the motor controller board.

Any part that rotates during printing, such as the drum or fuser.

Only if there is a clear, visible paper jam. Internal motor faults require service.
