8 - 172
MJ-1106
[CC80] Front alignment motor (M2) abnormality
MJ-1032
Rear alignment motor (M10) Check the connectors and harnesses between the rear
alignment motor (M10) and the finisher control PC board
(CN10).
Replacement part Measure
Rear alignment motor (M10)
Finisher control PC board
Check Item Measure
Rear alignment plate If there is mechanical problem when the rear alignment plate is
moved, fix the mechanism.
Rear alignment motor (M6) Check the connectors and harnesses between the rear
alignment motor (M6) and the finisher control PC board (CN17).
Replacement part Measure
Rear alignment motor (M6)
Finisher control PC board
Error Timing of detection
Front alignment motor (M2)
Front alignment plate home position
sensor (S5) The turning OFF of the front alignment plate home position sensor (S5)
is not detected when the front alignment plate is moved from a point
where this sensor is turned ON to one point where this sensor is turned
OFF after the front alignment motor (M2) has been driven at the
specified number of pulse.
The turning ON of the front alignment plate home position
sensor (S5) is not detected when the front alignment plate is
moved from a point where this sensor is turned OFF to one
point where this sensor is turned ON after the front alignment
motor (M2) has been driven at the specified number of pulse.
Probable cause Checking and measures
Front alignment motor (M2)
abnormality
Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the motor.
Front alignment plate home position
sensor (S5) abnormality Measure the voltage on TP15 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.
Faulty cables and connectors 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)
Finisher control PC board (FIN)
abnormality
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
