ERROR CODE AND TROUBLESHOOTING
8 - 91
[EA31] Transport jam in Finisher
MJ-1036
[EA31] Transport path paper remaining jam
MJ-1107
Stationary tray full detection
sensor (S11) abnormality Measure the voltage on TP26 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 connector.
(Finisher control PC board (FIN): CN6, CN10, CN22)
Finisher control PC board
(FIN) abnormality If the error still occurs after replacing the sensor and the connector,
replace the finisher control PC board (FIN).

Entrance path sensor (S19)
abnormality 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.
Middle path sensor (S7)
abnormality 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.
Sub-path sensor (S8)
abnormality 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.
Faulty cables and connectors 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)
Finisher control PC board
(FIN) abnormality If the error still occurs after replacing the sensor and the connector,
exchange the finisher control PC board (FIN).
