abnormality
Measure the voltage on TP67 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 3.3V5% 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): CN6, CN16)
