ERROR CODE AND TROUBLESHOOTING
Paper transport jam in the Finisher (Middle path sensor)
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 TP86 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.
Measure the voltage on TP84 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.
Check if the electrical continuity between the connector terminals is
normal. If electricity is not conducted, replace the connector.
(Finisher control PC board (FIN): CN6, CN14, CN22)
If the error still occurs after replacing the sensor and the connector,
replace the finisher control PC board (FIN).
