• Code: EAF1
• Description: Stack exit roller nip motor home position detection error: The detection of the home position of the stack exit roller nip motor ends abnormally. This error may occur if paper is jammed while being transported, so it is treated as a paper jam. [MJ-1032/MJ-1033]
• Causes:
• Remedy:

• Code: EAF2
• Description: Stapler unit sliding motor home position detection error: The detection of the home position of the stapler unit sliding motor ends abnormally. This error may occur if paper is jammed while being transported, so it is treated as a paper jam. [MJ-1032/MJ-1033]
• Causes:
• Remedy:

• Code: EAF3
• Description: Gripper arm motor home position detection error: The detection of the home position of the gripper arm ends abnormally. This error may occur if paper is jammed while being transported, so it is treated as a paper jam. [MJ-1033]
• Causes:
• Remedy: Gripper motor (M3) abnormality Check if the electrical continuity of the coil is normal. If electricity is not conducted, replace the motor. Gripper arm home position sensor (S13) abnormality Measure the voltage on pin CN10.8 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. Gripper arm exit sensor (S26) abnormality Measure the voltage on TP27 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 If the error still occurs after replacing the motor, sensors and connectors, exchange the finisher control PC board (FIN). Finisher control PC board (FIN) abnormality If the error still occurs after replacing the motor, sensors and connectors, exchange the finisher control PC board (FIN).

• Code: EB30
• Description: Ready time time-out jam: The equipment judges that the paper transport to the finisher is disabled because of the communication error between the equipment and finisher at the start of printing.
• Causes: IPC board LGC board Finisher controller PC board
• Remedy: Finisher Check if the connector on the equipment is disconnected from the finisher or the harnesses are open circuited. Correct if any.

• Code: EB50
• Description: Paper remaining on the transport path: The multiple feeding of preceding paper caused the misfeeding of upcoming paper.
• Causes: Registration sensor LGC board Rollers on the transport path
• Remedy: 1 ADU Open the ADU and remove paper if there is any on the transport path. 2 2 Is the registration sensor working? (Perform the input check: 03-[FAX]/ON/ [9]/[A]) Yes Check the rollers. Replace them if they are worn out No 3 3 LGC board 1. Check if the connector CN316 on the LGC board is disconnected. 2. Check if the connector pins are disconnected or the harnesses are open circuited. 3. Check if the conductor patterns on the LGC board are short circuited or open circuited.

• Code: EB60
• Description: Paper remaining on the transport path: The multiple feeding of preceding paper caused the misfeeding of upcoming paper (redetection after no jam is detected at [EB50]).
• Causes: Registration sensor LGC board Rollers on the transport path
• Remedy: 1 Open the Automatic duplexing unit. Is there any paper in front of the registration sensor? Yes Remove the paper. No 2 2 Is the registration sensor working? (Perform the input check in the test mode: 03- [FAX]OFF/[6]/[E]) Yes 3 No • Check if the connector CN316 on the LGC board is disconnected. • Check if the connector of the registration sensor is disconnected. • Check if the connector pins are disconnected and the harnesses are open circuited. • Check if the conductor pattern on the LGC board is short circuited or open circuited. • Replace the registration sensor. • Replace the LGC board. 3 Roller • Check the rollers. Replace them if they are worn out.

• Code: ED10
• Description: Skew adjustment motor (M1) home position detection abnormality: The Skew adjustment motor is not at the home position. [MJ-1101/MJ-1106 (when MJ-6103 is installed)]
• Causes: Skew adjustment motor Hole punch control PC board
• Remedy: Skew adjustment motor Rotate skew adjustment motor and fix its mechanism if it does not rotate smoothly. Skew HP sensor Skew adjustment motor Hole punch control PC board Check if the connectors on the hole punch controller PC board (HP board) are disconnected from the skew HP sensor (S2) and the skew adjustment motor, or the harnesses are open circuited. Correct if any.

• Code: ED11
• Description: Sideways adjustment motor (M2) home position detection error: The Sideways adjustment motor is not at the home position. [MJ-1101/MJ-1106 (when MJ-6103 is installed)]
• Causes: Sideways adjustment motor Hole punch control PC board
• Remedy: Sideways adjustment motor Rotate sideways adjustment motor and fix its mechanism if it does not rotate smoothly. sideways deviation HP sensor Sideways adjustment motor Hole punch control PC board Check if the connectors on the hole punch controller PC board (HP board) are disconnected from the sideways deviation HP sensor (S3) and the sideways adjustment motor, or the harnesses are open circuited. Correct if any.
