ERROR CODE AND TROUBLESHOOTING
8 - 124
[EA2B] Paper transport jam in the Finisher (Middle path sensor)
MJ-1032
[EA2C] Paper transport jam in the Finisher (Entrance path - sub-path sensor)
MJ-1032
Classification Error content
Paper jam in finisher section Paper transport jam in the Finisher (Middle path sensor)
Probable cause Checking and measures
2nd transport motor (M4)
abnormality
Check if the electrical continuity of the coil is normal. If electricity is
not conducted, replace the motor.
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.
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, CN14, 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).
Classification Error content
Paper jam in finisher section Paper transport jam in the Finisher (Entrance path - sub-path
sensor)
Probable cause Checking and measures
1st transport motor (M8)
abnormality
Check if the electrical continuity of the coil is normal. If electricity is
not conducted, replace the motor.
2nd transport motor (M4)
abnormality
Check if the electrical continuity of the coil is normal. If electricity is
not conducted, replace the motor.
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.
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.
