  • 1Toner dust buildup clogging gears.
  • 2Drum unit mechanical overload.
  • 3Main motor end-of-life.
  • 4Speed sensor blockade.

Solutions

Diagnostic Overview

The error appears upon startup. If you see excessive toner dust near the motor when opening the side panels, dirt might be causing the jam.

Step-by-step Solution

  1. Power off and unplug.
  2. Remove the image unit to release the motor.
  3. Turn gears manually to detect resistance.
  4. Clean residual toner from the motor area.
  5. Restart to see if the error is cleared.

Maintenance and Prevention

Avoid poor quality compatible consumables, as they may have toner densities that clog the developer. Clean gears monthly.

When to call a technician

If the motor does not turn smoothly when activated even without units, the motor itself is faulty or the main gear has broken teeth.
