Checking and measures
Measure the voltage on TP67 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.
Check if the electrical continuity between the connector
terminals is normal. If electricity is not conducted, replace the
connectors. (Finisher control PC board (FIN): CN6, CN16)
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
Timing of detection
The turning OFF of the saddle stitch staple unit clinching home
position sensor (S32) is not detected in the specified time when
saddle stitch stapling is performed.
The turning ON of the saddle stitch staple unit clinching home
position sensor (S32) is not detected in the specified time after
the turning OFF of this sensor had been detected when saddle
stitch stapling is performed, and also the turning ON of this
sensor is not detected in a reverse rotation after the saddle
stitch stapler is stopped.
Checking and measures
Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the saddle stitch staple unit.
Measure the voltage on pin CN17.5 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 saddle stitch staple unit.
Check if the electrical continuity between the connector
terminals is normal. If electricity is not conducted, replace the
saddle stitch staple unit.
If the error still occurs after replacing the saddle stitch staple
unit and the connectors, exchange the finisher control PC board
(FIN).
Measure the voltage on pin CN17.7 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 saddle stitch staple unit.
Check if the electrical continuity between the connector
terminals is normal. If electricity is not conducted, replace the
saddle stitch staple unit.
If the error still occurs after replacing the saddle stitch staple
unit and the connector, exchange the finisher control PC board
(FIN).
