the drum, the output value is out of the prescribed range.
-
 Potential sensor defective
 Potential sensor harness disconnected
 Potential sensor connector defective or disconnected
 IOB defective
 OPC connector defective
 Development power pack defective
SC380-11
C
Potential sensor calibration error (VM800)
During drum potential sensor calibration, when -800V is applied to
the drum, the output value is out of the prescribed range.
-
 Potential sensor defective
 Potential sensor harness disconnected
 Potential sensor connector defective or disconnected
 IOB defective
 OPC connector defective
 Development power pack defective
SC380-21
C
Potential sensor calibration error (skew)
During drum potential sensor calibration, the drum potential sensor
output voltage does not meet specification when test voltages
(–100V, –800V) are applied to the drum.
-
 Potential sensor defective
 Potential sensor harness disconnected
 Potential sensor connector defective or disconnected
 IOB defective
 OPC connector defective
 Development power pack defective
