[CB51] Stapler shift home position error
MJ-1101
Edge staple unit motor
Edge staple unit clinching home
position sensor The turning OFF of the edge staple unit clinching home position
sensor (S29) is not detected in the specified time when stapling
is performed.
The turning ON of the edge staple unit clinching home position
sensor (S29) is not detected after the specified time has passed
since the turning OFF of this sensor had been detected when
stapling is performed, and also turning ON of this sensor is not
detected in a reverse rotation after the stapler is stopped.
Probable cause Checking and measures
Edge staple unit motor (M13)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the staple unit.
Edge staple unit clinching home
position sensor (S29) abnormality
Measure the voltage on pin CN10.4 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 5V
±
5% when OFF. If the voltage does not fall within the range mentioned,
replace the staple unit.
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.
Edge staple unit interference
switch (SW3) abnormality
Measure the voltage on pin CN18.8 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower when the
switch is ON and within the range of 24V
±
10% when OFF. If the voltage does not fall within the range mentioned,
replace the switch. (Be sure that all covers and doors are closed
before starting measurement.)
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): CN10, CN18, CN24)
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).
Classification Contents
Finisher related service call Stapler shift home position error: The stapler is not at the home
position.
Check Item Measure
Stapler If there is mechanical problem when the stapler is moved, fix
the mechanism.
Stapler unit home position sensor
(S10) • Sensor check
• Check the connectors and harnesses between the stapler
unit home position sensor (S10) and the finisher control PC
board (CN1).
Stapler unit shift motor (M4) Check the connectors and harnesses between the stapler unit
shift motor (M4) and the finisher control PC board (CN5).
