ERROR CODE AND TROUBLESHOOTING
8 - 149
[CB50] Staple motor (M10) abnormality
MJ-1032
[CB50] Edge staple unit motor (M13) abnormality
MJ-1033
Error Timing of detection
Stapler motor (M9)
Staple unit clinching home position
sensor (S16) The staple unit clinching home position sensor (S16) does not
detect the opening of the staple unit after the stapler motor (M9)
has been driven reversely in the specified time from the closing
during the initial movement of the staple unit.
The staple unit clinching home position sensor (S16) does not
detect the opening of the staple unit in the specified time from
the closing during the clinching movement of the staple unit,
and also this sensor does not detect the opening by the reverse
rotation of the motor after the stapler is stopped.
The staple unit clinching home position sensor (S16) does not
detect the closing of the staple unit after the specified time
during the clinching movement of the staple unit.
The staple unit clinching home position sensor (S16) does not
detect the opening of the staple unit at the start of the clinching.
Probable cause Checking and measures
Staple motor (M10) abnormality Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the staple unit.
Staple unit clinching home position
sensor (S16) abnormality Measure the voltage on CN16 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower
when the sensor is ON and within the range of 3.3V
±
5% when OFF. If the voltage does not fall within the range
mentioned, replace the staple unit.
Staple unit improper clinching
prevention sensor (S15)
abnormality Measure the voltage on TP25 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): CN16, CN17)
Finisher control PC board (FIN)
abnormality If the error still occurs after replacing the motor, sensors, switch
and connectors, exchange the finisher control PC board (FIN).
Error Timing of detection
Staple unit sliding motor
Edge staple unit improper clinching
prevention sensor The turning OFF of the edge staple unit improper clinching
prevention sensor (S25) 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 improper clinching
prevention sensor (S25) 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.
