Troubleshooting for SC Errors
2. Check for a broken harness or connector disconnection.
3. If the problem cannot be solved, replace the Imaging IOB.
Countermeasure (6): Laser optics positioning motor in laser unit error
1. Check the operation of the laser optics positioning motor and check for a broken harness or connector disconnection. If an abnormality is detected, replace the Laser Unit.
2. If the problem cannot be solved, replace the Imaging IOB.
6.12.2 WHEN SC370 (TM (ID) SENSOR CALIBRATION ERROR) IS DISPLAYED
Causes
TM (ID) sensor connector missing/connection error
TM (ID) sensor detection window dirt
TM (ID) sensor malfunction
Undulation in the ITB, or belt slippage
Solutions
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 with dump cloth (never use a dry cloth or alcohol).
3. Check if there is an abnormality on the image transfer belt surface.
4. 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
5. Check the TM/ID sensor for malfunctions, and recover or replace it if there are any defects.
6. Check the harness. Replace the harness if it is disconnected, or damaged.
7. If the SC is not cleared even after performing steps 1 to 6, replace the BCU
Recovery Check Procedure
1. Execute Vsg adjustment with SP3-320-001(Vsg Adj: Execute :P Sensor).
2. Check the result with SP3-323-001(Vsg Adj OK?: Latest).
If code is "1": Recovered
If code is not "1": Not recovered
