ERROR CODE AND TROUBLESHOOTING
8 - 152
[CB51] Staple unit sliding motor (M11) abnormality
MJ-1033
[CB60] Stapler unit shift motor abnormality
MJ-1101
Error Timing of detection
Staple unit slidingEdge staple unit
sliding home position sensor motor The turning OFF of the edge staple unit sliding home position sensor
(S14) is not detected in the specified time when the edge staple unit 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 edge staple unit sliding home position sensor
(S14) is not detected in the specified time when the edge staple unit 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
Staple unit sliding motor (M11)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the staple unit.
Edge staple unit sliding home
position sensor (S14) abnormality
Measure the voltage on pin CN7.6 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.
Saddle stitch staple unit sliding home
position sensor (S22) abnormality Measure the voltage on pin CN7.10 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.
Edge staple unit improper clinching
prevention sensor (S25)
abnormality
Measure the voltage on pin CN10.11 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): CN7, CN10, CN17)
Finisher control PC board (FIN)
abnormality
If the error still occurs after replacing the staple unit, sensors and
connectors, exchange the finisher control PC board (FIN).
Classification Contents
Finisher related service call Stapler shift motor abnormality: Stapler shift motor is not
rotating or staple unit is not moving normally.
Check Item Measure
Stapler If there is mechanical problem when the stapler is moved, fix
the mechanism.
Stapler unit shift motor (M4) Check the connectors and harnesses between the stapler unit
shift motor (M4) and the finisher control PC board (CN5).
Replacement part Measure
Stapler unit shift motor (M4)
Finisher controller PC board
