ERROR CODE AND TROUBLESHOOTING
6 - 36
[EB50]Paper left on the transport path due to multiple feeding
When the paper is fed from the upper drawer:
1. Open the ADU and remove paper if there is any on the transport path.
2. Is the registration sensor working? (Perform the input check: 03-[FAX]/ON/[9]/[A])
* If it is working normally, go to step 8. If it is not, check 3 to 7.
3. Check if the connector CN316 on the LGC board is disconnected.
4. Check if the connector pins are disconnected or the harnesses are open circuited.
5. Check if the conductor patterns on the LGC board are short circuited or open circuited.
6. Replace the registration sensor.
7. Replace the LGC board.
8. Check the rollers. Replace them if they are worn out
When the paper is fed from the bypass tray:
1. Open the ADU and remove paper if there is any on the transport path.
2. Is the 1st transport sensor working? (Perform the input check: 03-[FAX]/OFF/[6]/[A])
* If it is working normally, go to step 8. If it is not, check 3 to 7.
3. Check if the connector CN316 on the LGC board is disconnected.
4. Check if the connector pins are disconnected or the harnesses are open circuited.
5. Check if the conductor patterns on the LGC board are short circuited or open circuited.
6. Replace the 1st transport sensor.
7. Replace the LGC board.
8. Is the registration sensor working? (Perform the input check in the test mode: 03-[FAX]ON/[9]/
[A])
* If it is working normally, go to step 14. If it is not, check 9 to 13.
9. Check if the connector CN316 on the LGC board is disconnected.
10.Check if the connector pins are disconnected or the harnesses are open circuited.
11.Check if the conductor patterns on the LGC board are short circuited or open circuited.
12.Replace the registration sensor.
13.Replace the LGC board.
14.Check the rollers. Replace them if they are worn out
When the paper is fed from the lower drawer:
1. Open the ADU and remove paper if there is any on the transport path.
2. Is the registration sensor working? (Perform the input check: 03-[FAX]/ON/[9]/[A])
* If it is working normally, go to step 8. If it is not, check 3 to 7.
3. Check if the connector CN316 on the LGC board is disconnected.
4. Check if the connector pins are disconnected or the harnesses are open circuited.
5. Check if the conductor patterns on the LGC board are short circuited or open circuited.
6. Replace the registration sensor.
7. Replace the LGC board.
8. Check the rollers. Replace them if they are worn out
When the paper is fed from the PFP or LCF
1. Open the feed cover and remove paper if there is any on the transport path.
2. Is the 2nd transport sensor working? (Perform the input check: 03-[FAX]/OFF/[7]/[A])
* If it is working normally, go to step 8. If it is not, check 3 to 7.
3. Check if the connector CN316 on the LGC board is disconnected.
4. Check if the connector pins are disconnected or the harnesses are open circuited.
5. Check if the conductor patterns on the LGC board are short circuited or open circuited.
6. Replace the 2nd transport sensor.
7. Replace the LGC board.
8. Check the rollers. Replace them if they are worn out
