Common causes

  • 1Physical obstruction by paper scraps in the ADF.
  • 2Worn or sticky feeder motor rollers.
  • 3Rotation sensor failure.
  • 4Short circuit in the motor power wiring harness.

Solutions

Quick Diagnosis

If you hear humming or friction sounds from the ADF unit, the C-5151 error is likely a physical jam. Ensure no debris is blocking the ADF rollers.

Step-by-Step Solution

  1. Emergency Shutdown: Stop the unit to prevent motor burnout.
  2. ADF Inspection: Open the ADF cover and search for scraps of paper that might jam the gears.
  3. Restart: Once cleared, reboot to test if the motor rotates correctly.

Prevention and Maintenance

Clean the feeder rollers monthly using rubber-safe cleaning agents. Avoid feeding staples, clips, or tape that can easily jam the rotation mechanism.

When to Call a Technician

If the motor remains unresponsive after removing physical obstructions, the ADF motor or its controller board requires replacement by a technician.
