[E510] ADU transport stop jam
1. Open the ADU and check if there is any paper in front of the ADU entrance sensor.
* If the error still occurs, check the following.
2. Is the ADU entrance sensor working? (Perform the input check: 03-[FAX]ON/[4]/[B])
* If it is working properly, proceed to 7. If not, check 3 to 6 below.
3. Check if the connectors CN511 on the PFC board is disconnected from the ADU entrance sensor
or the harnesses are open circuited. Check if the connectors CN491 and CN492 on the ADU
board are disconnected. Correct if any.
4. Replace the ADU entrance sensor.
5. Replace the ADU board.
6. Replace the PFC board.
7. Is the reverse motor working? (Perform the output check: 03-132/134)
* If it is working properly, proceed to 11. If not, check 8 to 10 below.
8. Check if the connector CN515 on the PFC board is disconnected from the reverse motor or the
harnesses are open circuited. Correct if any.
9. Replace the reverse motor.
10.Replace the PFC board.
11.Is the ADU motor working? (Perform the output check: 03-144)
* If it is working properly, proceed to 16. If not, check 12 to 15 below.
12.Check if the connectors CN511 on the PFC board is disconnected from the ADU motor or the

disconnected. Correct if any.
13.Replace the ADU motor.
14.Replace the ADU board.
15.Replace the PFC board.
16.Check the rollers in the ADU, the exit roller and the pressure spring of the equipment. Replace
them if they are worn out.
[E511]Jam not reaching the ADU (Paper not reaching the duplexing unit path entrance sensor)
1. Is the duplexing unit path entrance sensor working? (Perform the input check: 03-[SCAN]ON/[3]/
[H].)
* If it is working properly, proceed to 6. If not, check 2 to 5 below.
2. Check if the connector CN511 on the PFC board is disconnected from the duplexing unit path
entrance sensor or the harnesses are open circuited. Correct if so (including CN491 and CN492
on the ADU board).
3. Check if the duplexing unit path entrance sensor is correctly installed or the actuator is properly
moved.
4. Replace the duplexing unit path entrance sensor.
5. Replace the PFC board.
6. Are the reverse motor and the ADU motor-1 working? (Perform the output check: 03-134, 03-
146.)
* If they are working properly, proceed to 11. If not, check 7 to 10 below.
7. Check if the connector CN515 on the PFC board is disconnected from the reverse motor or the
ADU motor-1, or the harnesses are open circuited. Correct if so (including CN537 and CN539 on
the DRV board).
8. Replace the reverse motor or the ADU motor-1.
9. Replace the DRV board.
10.Replace the PFC board.
11.Check if there is any abnormality on the driving section of each motor or the roller. Correct if any.
