SC361 - Incomplete drum potential sensor calibration
Definition: [level: C]
When the process control initial setting is performed and a development
bias of –100 V or –800 V is applied to the drum shaft, the drum potential
voltage is out of these ranges:
0.1 ≤ V–100 ≤ 0.7 [V] or 2.7 ≤ V–800 ≤ 4.2 [V].
Possible causes:
•
Drum potential sensor defective
•
Drum shaft terminal not grounded
•
OPC drum
•
Main charge corona unit defective
