Kyocera ECOSYS P4060dn error C4000: How to Resolve

The Kyocera ECOSYS P4060dn error C4000 indicates a malfunction within the main drive motor. This critical error occurs when the printer system detects that the motor cannot reach the required speed or is facing excessive physical load. Proper diagnosis is necessary to determine if it is a simple jam or a mechanical failure.

  • 1Hidden paper jam inside the transport unit.
  • 2Main motor bearing friction or seizure.
  • 3Motor control signal loss.
  • 4Drive gear misalignment.

Solutions

Quick Diagnosis

If the printer halts with C4000, consider the last print job. If the machine was struggling with a thick paper stack or an intense document, it may have simply entered a protect mode due to torque overload.

Step-by-Step Fix

  1. Unplug: Disconnect the power for a full 5 minutes to reset the drive controller.
  2. Path Audit: Thoroughly inspect the paper transport area to ensure no paper scraps are causing friction.
  3. Manual Check: Verify that the internal rollers turn freely without grating sounds.
  4. Power Up: Reconnect the device and initiate a restart to clear the drive fault.

Prevention and Maintenance

Use only high-quality paper to reduce the likelihood of internal jams that strain the drive train. Schedule an annual inspection to clean and calibrate the drive system.

When to Call a Technician

If the error returns immediately upon power-up, the internal drive motor may be burnt out or the control PCB might be faulty, requiring professional repair.
