ERROR CODE AND TROUBLESHOOTING
8 - 151
MJ-1106
[CB51] Staple unit sliding motor (M7) abnormality
MJ-1032
Replacement part Measure
Stapler unit home position sensor
(S10)
Finisher controller PC board
Check item Measures
Stapler Move the stapler.
Fix any mechanical problem.
Stapler unit home position
sensor Check if there is a disconnection of the connector, incorrect
installation or breakage of the stapler unit home position sensor
(S10). If there is, reinstall the sensor correctly or replace it.
Check if the connector (CN21) on the finisher controller PC board is
disconnected from the stapler unit home position sensor (S10) and
the harnesses are open circuited. Correct if so.
Stapler unit shift motor Check if the connector (CN10) on the finisher controller PC board is
disconnected from the stapler unit shift motor (M9) and the
harnesses are open circuited. Correct if so.
Parts to be replaced Remark
Stapler unit home position
sensor
Finisher controller PC board
Error Timing of detection
Staple unit sliding motor (M7)
Staple unit sliding home position
sensor (S3) The turning OFF of the staple unit sliding home position sensor (S3) is
not detected when the staple unit is moved from a point where this
sensor is turned ON to one point where this sensor is turned OFF after
the staple unit sliding motor (M7) has been driven at the specified
number of pulse.
The turning ON of the staple unit sliding home position sensor (S3) is
not detected when the staple unit is moved from a point where this
sensor is turned OFF to one point where this sensor is turned ON after
the staple unit sliding motor (M7) has been driven at the specified
number of pulse.
Probable cause Checking and measures
Staple unit sliding motor (M7)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the staple unit.
Staple unit sliding home position
sensor (S3) abnormality Measure the voltage on TP18 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): CN3, CN18)
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).
