Change the value in SP3-322-021 to 023 to "30mA", and then check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps.

  1. Check if all connectors related to TM/ID sensor are connected securely. Reconnect the connectors if they are disconnected, or loose.
  2. If TM/ID sensor is contaminated, clean it (never use a dry cloth).
  3. Check the harness. Replace the harness if it is disconnected, or damaged.
  4. Check if there is an abnormality on the image transfer belt surface.
  5. If any abnormalities are found on the image transfer belt surface, replace the image transfer belt.
    • Belt scratched
    • Belt corrugation, belt skew
    • Cleaning failure
    • Background stains
    • Filming
  6. If the SC is not cleared even after performing steps 1 to 5, replace the BICU (PCB10).
