• Code: EA20
• Description: Paper transport stop jam: The paper does not pass through the inlet sensor. [MJ-1025/MJ-1031] Paper transport stop jam: The paper has passed through the inlet sensor but does not reach or pass the feed path sensor or processing tray sensor. [MJ-1024] Paper transport delay jam: The paper which has passed through the inlet sensor does not reach the transport sensor. [MJ- 1101
• Remedy: MJ-1025 Is there any paper remaining on the transport path in the finisher? YES Remove the paper. NO Is the connector CN16 (inlet sensor) on the finisher controller PC board disconnected? Is the harness connecting the finisher controller PC board and inlet sensor open-circuited? YES Connect the connector securely. Replace the harness. NO Is the inlet sensor working normally? (Check the movement of the actuator.) l NO 1. Attach the actuator securely if its shaft is out of place. 2. Replace the sensor. YES Replace the finisher controller PC board.

Is the inlet sensor working properly? (Check the movement of the actuator.) 4. Replace the inlet sensor. 5. Replace the finisher controller PC board.
  MJ-1101 1. Check if there is any paper in the finisher or on the transport path of the equipment and remove it if there is. 2. Check if the connector on the finisher controller PC board is disconnected from the transport sensor (S2) or the harnesses are open circuited. Correct if any. 3. Replace the sensor. 4. Replace the finisher controller PC board.

• Code: EA21

• Remedy: MJ-1101 1. Check if there is any paper in the finisher or on the transport path of the equipment and remove it if there is. 2. Is the paper size used shorter than the size specified in the specifications? 3. Check if the connectors CN7 and CN22 on the finisher controller PC board are disconnected from the entrance sensor (S1) and the transport sensor (S2), or the harnesses are open circuited. Correct if any. 4. Replace the sensor. 5. Replace the finisher controller PC board.

• Code: EA22
