6.2.7 Jam in bridge unit
[E910] Paper not reaching the bridge unit transport sensor-1
[E920] Paper stopping at the bridge unit transport sensor-1
1. Check if there is any paper in the bridge unit and remove it if there is.
2. Is the bridge unit transport sensor-1 working? (Perform the input check:03-[FAX]OFF/[5]/[F])
* If it is working properly, proceed to 6. If not, check 3 to 5 below.
3. Check if the connector CN334 on the LGC board is disconnected from the bridge unit transport
sensor-1 (entrance sensor) or the harnesses are open circuited. Check if the connector J523 of
the bridge unit is disconnected. Correct if any.
4. Replace the bridge unit transport sensor-1.
5. Replace the LGC board.
6. Is the bridge unit gate solenoid working? (Perform the output check: 03-232)
* If it is working properly, proceed to 10. If not, check 7 to 9 below.
7. Check if the connector CN334 on the LGC board is disconnected from the bridge unit gate
solenoid or the harnesses are open circuited. Check if the connector J523 of the bridge unit is
disconnected. Correct if any.
8. Replace the bridge unit gate solenoid.
9. Replace the LGC board.
10.Does the transport roller of the bridge unit work when the fuser motor is rotated? (Perform the
output check: 03-113/163)
* If it is working properly, proceed to 12. If not, check 11 below.
11.Check the drive system of the equipment and bridge unit.
12.Check if the rollers in the exit roller, the pressure spring and the bridge unit are worn out.
[E930] Paper not reaching the bridge unit transport sensor-2
[E940] Paper stopping at the bridge unit transport sensor-2
1. Check if there is any paper in the bridge unit and remove it if there is.
2. Is the bridge unit transport sensor-2 working? (Perform the input check:03-[FAX]OFF/[5]/[D])
* If it is working properly, proceed to 6. If not, check 3 to 5 below.
3. Check if the connector CN334 on the LGC board is disconnected from the bridge unit transport
sensor-2 (exit sensor) or the harnesses are open circuited. Check if the connector J523 of the
bridge unit is disconnected. Correct if any.
4. Replace the bridge unit transport sensor-2.
5. Replace the LGC board.
6. Does the transport roller of the bridge unit work when the fuser motor is rotated? (Perform the
output check: 03-113/163)
* If it is working properly, proceed to 8. If not, check 7 below.
