  MJ-1033 Saddle stitch finishing tray sensor (S7) abnormality Measure the voltage on TP65 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. Saddle stitch exit path sensor (S5) abnormality Measure the voltage on TP68 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): CN15, CN16) Finisher control PC board (FIN) abnormality If the error still occurs after replacing the sensors and the connectors, exchange the finisher control PC board (FIN).
