ERROR CODE AND TROUBLESHOOTING
The turning OFF of the rear alignment plate home position
sensor (S6) is not detected when the rear alignment plate is
moved from a point where this sensor is turned ON to one point
where this sensor is turned OFF after the rear alignment motor
(M3) has been driven at the specified number of pulse.
The turning ON of the rear alignment plate home position
sensor (S6) is not detected when the rear alignment plate is
moved from a point where this sensor is turned OFF to one
point where this sensor is turned ON after the rear alignment
motor (M3) has been driven at the specified number of pulse.
Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the motor.
Measure the voltage on TP16 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower
when not shielded and within the range of 3.3V±5% when
shielded. If the voltage does not fall within the range mentioned,
replace the sensor.
Check if the electrical continuity between the connector
terminals is normal. If electricity is not conducted, replace the
connectors. (Finisher control PC board (FIN): CN5, CN12)
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
Front alignment motor abnormality: The front alignment motor is
not rotating or the front alignment plate is not moving normally.
If there is mechanical problem when the front alignment plate is
moved, fix the mechanism.
Check the connectors and harnesses between the front
alignment motor (M9) and the finisher control PC board (CN10).
Measures
If there is mechanical problem when the front alignment plate is
moved, fix the mechanism.
