Troubleshooting
Step Confirmation and action YES NO
1

Check paper transport path

Is there any foreign matter, paper chips, etc. in the paper transport path?

Remove foreign matter, paper fragments, etc.

Go to step 2

2

Check the operation of the Duplex Paper Feed Sensor

Does the Duplex Paper Feed Sensor respond with the diagnostic function?

Judgment: Does the signal change between when the paper is placed and when it is not?

Go to step 4 Go to step 3
3

Check the Duplex Paper Feed Sensor for installation, dirt, and connector connection

Is the Duplex Paper Feed Sensor installed improperly? Is there dirt on the sensor? Is the connector not fully inserted?

Is the relay connector on the Right Door Unit side not inserted halfway?

Clean the sensor surface, or fully insert the connector.

Replace the Sensor

4

Check the Duplex Roller 1, Reversing Roller 1 and 2 for dirt and installation

Are the roller and sensor specified in the part to be checked installed properly? Make sure no dirt remains on the surfaces.

Go to step 5

Clean and reinstall the paper feed rollers.

5

Check the Duplex Roller 1, Reversing Roller 1 and 2 for deformation and wear

Are the rollers listed on the suspected part deformed or worn?

Replacement of applicable paper transport roller Go to step 6
6

Check the Duplex Paper Feed Path Paper Feed Clutch

Check the clutch operation using the failure diagnostic function.

Does it make an operating sound (clutch connection sound)?

Go to step 7 Go to step 9
7

Operation check of Reversal Drive Motor

Check the operation of the corresponding Reversal Drive Motor with the diagnostic function.

Judgment: Is there any abnormal noise?

Replace the Right Door Unit Go to step 8
8

Check if the Belt Unit is deformed or has failed

Is the Belt Unit listed in the “Assumed cause” section deformed or has it failed?

Replace the Belt Unit

Go to step 9

9

Check the All Drive Motor operation

Check the operation of the corresponding drive motor using the diagnostic function.

Judgment: Is there any abnormal noise?

Replace the gear train and All Drive Motor

Replace the MCU board
