A voltage value below the threshold value was detected with primary transfer ATVC control
for yellow
Remedy:
1. Check the harness between the Primary Transfer High Voltage PCB and the DC Controller PCB
(open circuit, caught cable, connector disconnection).
-> Replace the harness if it is faulty
2. Check the contact point between the ITB Unit and the Primary Transfer Power Feed Unit.
3. Execute primary transfer ATVC again.
-> If the abnormality is found again, perform the remedy shown below. If abnormality is not found,
continue use with careful attention.
4. Replace the Drum Unit of the corresponding station.
5. Replace the ITB Unit.
6. Replace the Primary Transfer High Voltage PCB.
7. Replace the DC Controller PCB.
