Probable cause
Checking and measures
Paper folding blade motor (M12)
abnormality
Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the motor.
Paper folding blade motor clock
sensor (S24) abnormality
Measure the voltage on TP66 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.
Paper folding blade home position
sensor (S19) abnormality
Measure the voltage on TP64 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): CN11, CN15)
