Title
Abnormal detected patch reading value
Detection Dark patch although setting 0 for the patch level (unable to fit in
the target between 550 and 640)
Remedy 1. Clean the scanner’s window.
2. Use your hand to check if the shutter of the Registration Patch
Sensor Unit can be open.
3. Check if the window of the Patch Sensor (UN43/ UN44) is
soiled.
4. Check scar on the ITB.
5. Check movement of the Registration Shutter Solenoid (SL02).
COPIER > FUNCTION > PART-CHK > SL to move SL02
6. Check the harness/connector between the DC Controller PCB
(UN09/J12) and the Patch Sensors (UN43/J4007, UN44, J4006).
7.Replace the Drum Unit (C)
8.Replace the Registration Patch Sensor Unit
9 Replace the ITB Unit.
10. Check conduction of the fuses (FU5, FU8) in the DC
Controller PCB (UN09).
11. Replace the Primary Transfer High Voltage PCB (UN04)
12. Replace the Developing High Voltage PCB (UN07)
13. Replace the Primary Charging High Voltage PCB (UN06)
14. Replace the Auxiliary High Voltage PCB (UN08)
15. Replace the Replace the DC Controller PCB (UN09)
