ID Sensor Calibration Error
The reflection light output voltage of the ID Sensor (Vsg_reg) is not adjusted
within the target range.
Upper limit: Default: 4.5 V
Lower limit: Default: 3.5 V
• Disconnected ID Sensor connectors
• Dirty or defective ID Sensors (S27-S29)
• Defective image transfer belt
To check if the issue is resolved:
1. Open the front door and check the result code in SP3-323-001.
Correct: The result is “111”
Incorrect: The result is not “111”
2. In the case of an error, make entries in the following SPs.
The result code "111" indicates the front, center and rear ID Sensors
(S27-S29).
For example "211" indicates an error at the front.
• If an error is detected at the front ID Sensor (S27): enter the
maximum value (50) in SP3-322-021.
• If an error is detected at the center ID Sensor (S28): enter the
maximum value (50) in SP3-322-022.
• If an error is detected at the rear ID Sensor(S29): enter the maximum
value (50) in SP3-322-023.
3. Close the front door.
4. Execute SP3-320-001.
5. Check the result code in SP3-323-001 again.
Troubleshooting procedure:
Check if the SC occurs by turning the power OFF then ON. If the SC occurs
again, do the following steps. Check if the SC reoccurs by cycling the power
after each step.
1. Check all the connectors are firmly connected.
If not, reconnect the connectors.
2. Clean the detecting parts of the ID Sensors (S27-S29)
• Do not wipe with a dry cloth. Wipe with a damp cloth.
3. Check the ID Sensor shutter.
If the shutter does not move correctly, replace the shutter solenoid.
4. Replace the drum and/or ITB if the following is found:
