2. Check the harness and connector for TM/ID sensor.
3. Replace the TM/ID sensor.
4. Replace the BCU.
Countermeasure (5): TM/ID Sensor Shutter Defective
Check if there is no problem concerning the mechanism (interference or deformation).
1. Execute SP5-804-255(OUTPUT Check: Paper Transfer Contact Operation) to operate the
Paper Transfer Contact Motor to check opening/closing of the shutter.
2. Check for a broken harness or connector disconnection.
3. If the problem cannot be solved, replace the Imaging IOB.
Countermeasure (6): Paper Transfer contact/release Mechanism Defective
Check if the MUSIC/ProCon Pattern is attached on the Paper Transfer Roller. If it is attached,
separating may be defective.
1. Execute SP5-804-255(OUTPUT Check: Paper Transfer Contact Operation) to operate the
Paper Transfer Contact Motor to check the separating operation of the Paper Transfer Roller.
2. Check for a broken harness or connector disconnection.
3. If the problem cannot be solved, replace the Imaging IOB.
Countermeasure (7): Skew Motor in Laser Unit Error
1. Check the operation of the Skew 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.
When SC370 (TM (ID) sensor calibration error) is Displayed
Cause:
• TM (ID) sensor connector missing/connection error
• TM (ID) sensor detection window dirt
• TM (ID) sensor malfunction
• Undulation in the ITB, or belt slippage
Solution:
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.
