Is the difference between
the actual measurement of
PR-CNT and the foregoing
value A /-10%?
Try replacing HVT1.
Is the fault corrected?
Is the difference between
the actual measurement of
GRID-CNT and the foregoing
value B /-10%?
Replace the DC
controller PCB.
Replace the DC
controller PCB.
<Check the Primary / Grid output>
Image adjustment basic procedure 2
Turn off the potential control mechanism:
COPIER>OPTION>BODY>P0-CNT '0'
Measure the voltage PR-CNT at
J1111B-9 found on the DC controller
PCB during copying operation.
Make the following selections in service
mode (primary current level of the
primary charging assembly):
COPIER>DISPLAY>HV-STS>PRIMARY.
Using the "Potential Control Conversion
Table," convert the reading (in uA)
indicated during printing operation into a
control voltage. Refer to the result as
conversion value A.
Measure the voltage GRID-CNT at
J111B-8 found on the DC controller PCB
during copying operation.
Make the following selections in service
mode (grid voltage level of the primary
charging assembly): COPIER>DISPLAY>
HV-STS>GRID. Using the "Potential
Control Conversion Table," convert the
reading (unit V) indicated during printing
operation into a control voltage. Refer to
the result as conversion value B.
Try replacing the
photosensitive drum.
Is the fault corrected?
