  MJ-1033 Transport motor-2 (M2) abnormality Check if the electrical continuity of the coil is normal. If electricity is not conducted, replace the motor. Saddle stitch entrance path sensor (S4) abnormality Measure the voltage on TP2 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 connectors. (Finisher control PC board (FIN): CN13, CN1) Finisher control PC board (FIN) abnormality If the error still occurs after replacing the motor, sensor and connectors, exchange the finisher control PC board (FIN).

• Code: EAC1
• Description: The detection of the home position of the folding blade motor ends abnormally.
• Causes:
• Remedy:

• Code: EAD0
• Description: Print end command time-out jam: The printing has not finished normally because of the communication error between the SYS board and LGC board at the end of printing.
• Causes: SYS board LGC board
• Remedy: 1 Is the main motor rotating normally? Yes No 2 2 Replacing the PC board • Replace the SYS board. • Replace the LGC board.

• Code: EAE0
• Description: Receiving time time-out jam: The printing has been interrupted because of the communication error between the equipment and finisher when the paper is transported from the equipment to the finisher.
• Causes: Finisher controller PC board
• Remedy: 1 Is the finisher working? Yes Replace the finisher controller PC board. No 2 2 Are the versions of the Finisher, Saddle Stitch Finisher and converter firmware the latest? Yes Download the firmware in the latest version. No 3 3 • Check if the voltage (24V) is being supplied to the finisher. • Check the connection of the LGC board and IPC board • Check if the harness connecting the IPC board and finisher I/F connector of the equipment side is open circuited. • Check if the harness connecting the I/F connector of the finisher side and finisher controller PC board is open circuited.
