30-0004 Pre-transfer Charging Movement: Pre-transfer charging high voltage is not output. An
PCB Harness
disconnection Cause: Connection error of the Pre-transfer Charging PCB
(connection error) (PCB26).
Measures:
1. Check the connection between the Main Driver PCB (PCB2)
and the High Voltage Unit.
Main Driver PCB side: J112, High Voltage Unit side: J3098
2. Check the connection inside of the High Voltage Unit.
High Voltage Unit inlet side: J3098, Pre-transfer Charging
PCB side: J3544
3. Replace the Pre-transfer Charging PCB (PCB26).
4. Replace the Main Driver PCB (PCB2).
31-0005 Environment Sensor Movement: It becomes as follow: environment temperature= 0
reading alarm
Cause: Connection of the Environment Sensor cannot be
detected.
Measures:
1. Check the connection of the Environment Sensor (THU1).
2. Replace the Environment Sensor (THU1).

control) error
Cause: The measured value in the dark area (VL) differs over
+/-10V but less than +/-30V than the target potential at
potential control.
Measures: If there is no influence on image, measures are not
1. Check the installation of the Pre-exposure LED (connector
connection, open circuit, the caught cable).
2. Check the installation of the Primary Charging Assembly
(connector connection, open circuit, the caught cable).
3. Check the fixation state of the Drum and the Drum Shaft
(check if the drum fixation cylinder is properly installed).
4. Check if the Dustproof Glass is soiled. If necessary, clean it.
5. Check the installation of the Laser Scanner Unit (connector
connection, open circuit, the caught cable).
6. Check the installation and connection of the Primary
Charging High Voltage PCB (PCB11) (connector connection,
open circuit, the caught cable).
7. Check the installation of the Potential Sensor (connector
connection, open circuit, the caught cable).
8. Check the installation and connection of the Drum Motor (M1)
(connector connection, open circuit, the caught cable).
9. Replace the parts.
