Common causes

  • 1Toner dust on the sensor optics.
  • 2Loose sensor connection.
  • 3Damaged encoder disk.
  • 4Electronic failure of proximity sensor.

Solutions

Quick Diagnosis

If the machine flags C0002, the rotation sensor is not seeing the encoder disk. Check the sensor for toner dust.

Step-by-step Solution

  1. Shut down the machine.
  2. Locate the rotation sensor near the drive motor.
  3. Wipe the sensor and encoder disk carefully with a dry swab.
  4. Restart the copier.

Prevention and Maintenance

Perform a deep internal vacuuming/cleaning every 10,000 prints to keep debris away from these sensitive feedback components.

When to call a technician

If the sensor remains unresponsive after cleaning, a replacement sensor or board cable may be necessary.
