Checking and measures
Measure the voltage on TP12 on the finisher control PC board

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.
Measure the voltage on TP77 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower when
the switch is ON and within the range of 3.3V ± 5% when OFF. If the
voltage does not fall within the range mentioned, replace the switch.
Check if the electrical continuity between the connector terminals is normal.
If electricity is not conducted, replace the connector. (Finisher control PC
