ERROR CODE AND TROUBLESHOOTING
Checking and measures
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.
Measure the voltage on TP85 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, CN22)
If the error still occurs after replacing the sensor and the connector,
exchange the finisher control PC board (FIN).
