ERROR CODE AND TROUBLESHOOTING
8 - 173
[CC80] Front alignment motor (M6) abnormality
MJ-1033
[CC91] Gripper arm home position detection error
[CC92] Movable tray upper limit detection error
MJ-1033
Error Timing of detection
Front alignment motor
Front aligning plate home position
sensor The turning OFF of the front alignment plate home position sensor (S9)
is not detected in the specified time 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.
The turning ON of the front alignment plate home position sensor (S9)
is not detected in the specified time 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
Probable cause Checking and measures
Front alignment motor (M6)
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 (S9) abnormality
Measure the voltage on pin CN8.3 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): CN2, CN8)
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).
Error Timing of detection
Movable tray shift motor
Movable tray upper limit sensor The turning ON of the movable tray upper limit sensor (S16) is
detected.
Probable cause Checking and measures
Movable tray shift motor (M5)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the motor.
Movable tray shift motor clock
sensor (S15) abnormality
Measure the voltage on pin CN7.3 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.
Movable tray upper limit sensor
(S16) abnormality
Measure the voltage on TP35 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.
Movable tray lower limit sensor (S17)
abnormality Measure the voltage on TP28 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.
Movable tray middle sensor (S18)
abnormality
Measure the voltage on TP29 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.
