• Code: E510
• Description: Paper transport jam (ADU section) Jam not reaching the ADU transfer sensor: The paper does not reach the ADU transfer sensor after it is switchbacked in the exit section.
• Causes: ADU transfer sensor MAIN board Exit motor ADU exit sensor Rollers in the ADU Exit roller
• Remedy: 1 Open the right cover. Is there any paper in front of the ADU transfer sensor? Yes Remove the paper. No 2 2 Is the ADU transfer sensor working? (Perform the input check in the test mode: 03-[FAX]OFF/[1]/ [C]) Yes 3 No • Check if the connector of the ADU transfer sensor is disconnected. • Check if the connector CN17 on the MAIN board is disconnected. • Check if the connector pins are disconnected and the harnesses are open circuited. • Check if the conductor patterns on the MAIN board are short circuited or open circuited. • Replace the ADU transfer sensor. • Replace the MAIN board. 3 Is the exit motor (rotating in reverse) working? (Perform the output check in the test mode: 03-121/ 171) Yes 4 No • Check if the connector of the exit motor is disconnected. • Check if the connector pins are disconnected and the harnesses are open circuited. • Replace the exit motor. • Replace the MAIN board. 4 ADU • Check the rollers in the ADU and the exit roller of the equipment. Replace them if they are worn out.

• Code: E550
• Description: Paper remaining jam on the transport path: The paper is remaining on the transport path when printing is finished (caused by a multiple paper feeding).
• Causes: Sensor. MAIN board
• Remedy: 1 Open the cover of the unit/ area whose picture is blinking on the control panel. Is there any paper on the transport path? Yes Remove the paper. No 2 2 Is the sensor in the jamming area working? (Perform the input check in the test mode: refer to the following table) Yes 3 No • Check if the connector of the sensor is disconnected. • Check if any of the connectors on the MAIN board is disconnected. • Check if the connector pins are disconnected and the harnesses are open circuited. • Check if the conductor pattern on the MAIN board is short circuited or open circuited. • Replace the sensor. 3 MAIN board • Replace the MAIN board.

• Code: E714
• Description: Feed signal reception jam: The feed signal is received even no original exists on the original feeding tray.
• Causes: Original empty sensor RADF board
• Remedy: Original empty sensor • Sensor check (Perform the input check: 03-[8]/[B]) • Lever check • Connector check • Harness check RADF board • Board check • Connector check (PA5) • Harness check

• Code: E721
• Description: Jam not reaching the read sensor: The original does not reach the read sensor after it has passed the registration sensor (when scanning obverse side) or the reverse sensor (when scanning reverse side).
• Causes: Read sensor RADF board Transport roller-1 Transport roller-2
• Remedy: Transport roller-1 / Transport roller-2 Clean the transport roller-1 and transport roller-2 if they are stained. Read sensor • Sensor check (Perform the input check: 03-[8]/[G]) • Connector check • Harness check RADF board • Board check • Connector check (PA4) • Harness check

• Code: E725
• Description: Stop jam at the read sensor: The trailing edge of the original does not pass the read sensor after its leading edge has reached this sensor.
• Causes: Read sensor RADF board Transport roller-2
• Remedy: 1 Transport roller-2 Clean the transport roller if it is stained. 2 Read sensor • Sensor check (Perform the input check: 03-[8]/[G]) • Connector check • Harness check 3 RADF board • Board check • Connector check (PA4) • Harness check

• Code: E726
• Description: Stop jam at the exit sensor: The trailing edge of the original does not pass the exit sensor after its leading edge has reached this sensor.
• Causes: Original intermediate transport sensor RADF board Exit/reverse roller Replace it if it is worn out.
• Remedy: Exit/reverse roller Clean the exit/reverse roller if it is stained. Original intermediate transport sensor • Sensor check (Perform the input check: 03-[8]/[E]) • Connector check • Harness check RADF board • Board check • Connector check (PA4) • Harness check

• Code: EAD0
• Description: Print end command time-out jam: Jam occurred because print operation did not finish normally due to communication error on main board
• Causes: Main motor MAIN board
• Remedy: 1 Is the main motor working? (Perform the output check in the test mode: 03-101/ 151) Yes 2 No • Replace the main motor. 2 Replacing the PC board Replace the MAIN board.
