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.
    If TM/ID sensor is contaminated, clean it (never use a dry cloth).
  2. Execute SP5-804-255 (OUTPUT Check: Paper Transfer Contact Operation) to operate the Paper Transfer Contact and Release Motor (M18) to check opening/closing of the shutter.
  3. Check if there is an abnormality on the image transfer belt surface.
    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
  4. Check the TM/ID sensor (S48) for malfunctions, and recover or replace it if there are any defects.
  5. Check the harness. Replace the harness if it is disconnected, or damaged.
  6. If the SC is not cleared even after performing steps 1 to 6, replace the BICU (PCB10).
