C5100 Main high-voltage error
• While the main high-voltage output
remote signal is on, an alarm signal is
detected continuously for 400 ms.
Defective high volt-
age PWB.
Replace the high voltage PWB and check
for correct operation.
Leak of main high-
voltage.
Check the main charger unit and replace if
necessary (see page 1-5-25).
Poor contact in
connector termi-
nals.
Check the connection of connector YC7 on
the engine PWB and the continuity across
the connector terminals. Repair or replace if
necessary.
C5500 Drum surface potential sensor prob-
lem 1
• The sensor output is 0.5 V or less
when MC REM signal is turned on.
Poor contact in the
drum surface
potential sensor
connector termi-
nals.
Check the connection of connector YC5 on
the engine PWB. Reinsert the connector.
Also check for continuity within the connec-
tor cable. If none, repair or replace the
cable.
Defective drum
surface potential
sensor.
Replace the drum surface potential sensor.
Defective high volt-
age PWB.
Replace the high voltage PWB and check
for correct operation.
Defective engine
PWB.
Replace the engine PWB and check for cor-
rect operation.
C5510 Drum surface potential sensor prob-
lem 2
• The sensor output is 4.5 V or more
when the MC REM signal is turned on.
Defective drum
surface potential
sensor.
Replace the drum surface potential sensor.
Defective high volt-
age PWB.
Replace the high voltage PWB and check
for correct operation.
Poor contact in the
drum surface
potential sensor.
Check the connection of connector YC5 on
the engine PWB. Reinsert the connector.
Also check for continuity within the connec-
tor cable. If none, remedy or replace the
cable.
C5600 Drum surface potential problem 1
• The sensor output is 4.5 V or more.
• Potential adjustment in 30 times could
not raise the potential sensor value to
the predetermined.
Deteriorated main
charger.
Check the main charger wire and replace it if
necessary (see page 1-5-27).
Grid or main
charger shield is
dirty.
Clean the grid or main charger shield if nec-
essary.
Defective drum
surface potential
sensor.
Replace the drum surface potential sensor.
Defective high volt-
age PWB.
Replace the high voltage PWB and check
for correct operation.
Defective engine
PWB.
Replace the engine PWB and check for cor-
rect operation.
C5610 Drum surface potential problem 2
• The sensor output is 0.5 V or less.
• Potential adjustment in 30 times could
not lower the potential sensor value to
the predetermined.
Defective drum
surface potential
sensor.
Replace the drum surface potential sensor.
Defective high volt-
age PWB.
Replace the high voltage PWB and check
for correct op
eration.
Defective drum. Replace the drum (see page 1-5-44).
Defective engine
PWB.
Replace the engine PWB.
