Error Name/Error Condition/Major Cause/Solution
In Vd detection, which is done at the beginning of process
control, the measured potential (Vd) is converted to the
potential when -700 V is applied to the drum (Vd700) and
used to check the potential sensor.
Potential sensor probe connector disconnected
Potential sensor probe defective
Disconnect and reconnect the harness connecting the
IOB and potential sensor board, then check the sensor
again.
If this does not solve the problem, replace the potential
sensor probe.
