Checking and measures
Check if the electrical continuity of the coil is normal. If electricity is
not conducted, replace the motor.
Measure the voltage on TP26 on the hole punch control PC board.
Then check that the measured voltage is 1V or lower when not
shielded and within the range of 5V±5% when shielded. If the
voltage does not fall within the range mentioned, replace the
sensor.
Measure the voltage on 8 pin of CN6 on the hole punch control PC
board. Then check that the measured voltage is 3.0V or higher
when not shielded and 1.2 or lower 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 connector. (Hole
punch control PC board: CN3, CN4, CN5, CN6)
If the error still occurs after replacing the sensor and the connector,
replace the hole punch control PC board.
Replace the finisher control PC board (FIN).
