Kyocera TASKalfa 6002i Error C4000: Transport Jam Guide

The Kyocera TASKalfa 6002i error C4000 is a system warning triggered by the paper transport motor. If the sensors detect the motor is not rotating as expected, the system locks to protect internal hardware. This is a common issue typically caused by ignored paper debris or mechanical friction.

Common causes

  • 1Physical jam: Paper fragments blocking roller rotation.
  • 2Motor wear: Loss of torque necessary to drive paper.
  • 3Sensor failure: Sensor fails to detect the beginning of the transport cycle.
  • 4Overloaded paper: Excessive tray weight straining the entry motor.

Solutions

Diagnóstico rápido

If the machine shows C4000, listen for unusual mechanical sounds upon startup. If the paper doesn't move when attempting to clear the path, debris might be physically obstructing the motor's travel.

Solución paso a paso

  1. Check Tray: Open the paper tray and remove any bent sheets or debris blocking the rollers.
  2. Clean Rollers: Clean feed rollers with a damp cloth to improve paper traction.
  3. Reset Device: Power off and on the machine to let the motor verify its home position.
  4. Feed Test: Send a print job to verify that the rollers turn without resistance.

Prevención y mantenimiento

Don't overfill the trays. Keep the interior paper path free of debris and use genuine feed rollers to prevent slipping.

Cuándo llamar a un técnico

If the C4000 error persists after clearing the path, there might be a fault in the motor board or the harness controlling the transport drive.

Frequently asked questions

The C4000 error is caused by a transport motor anomaly or a physical blockage preventing paper movement.

If it is just a simple paper jam, cleaning the paper path will fix it; if the motor is dead, professional service is required.

This MFP uses TK-6325 toner cartridges, which are key to maintaining a clean transport system.

Use high-quality paper and perform periodic cleaning of feed rollers every three months.
