Punch sliding unit home position sensor abnormality 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. Paper detection sensor (lightreceiving/ light-emitting) (S24/ S25) 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. Faulty cables and connectors Check if the electrical continuity between the connector terminals is normal. If electricity is not conducted, replace the connector.
