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 any foreign objects or pieces of paper | Go to step 2 |
| 2 | Check the paper feed rollers/sensors for dirt and installation Are the rollers listed in the “Assumed cause” section clean and installed properly? |
Go to step 3 | Clean and reinstall the paper feed rollers. |
| 3 | Check the paper feed rollers for deformation and wear Are the rollers listed in the “Related parts” section deformed or worn? |
Replace the worn out or deformed roller | Go to step 4 |
| 4 | Check the Torque Limiter Can you rotate the Retard Roller by hand? |
Go to step 5 | Replace the retard torque limiter. |
| 5 | Checking operation of cassette paper feed sensor for paper feed Check the operation of the cassette paper feed sensor for the paper feed target with the diagnostic function Does the signal change between when the paper is placed and when it is not? |
Go to step 7 | Go to step 6 |
| 6 | Check the Paper Feed Sensor of the cassette for installation, dirt, and connection Is there a problem with the installation of the cassette paper feed sensor for the paper feed target? Is there dirt on the sensor? Is the connector not fully inserted? Is the connector of the paper feed unit of the paper feed target cassette half-inserted? |
Clean the sensor surface, reinstall the sensor, or fully insert the connector. | Replace the sensor |
| 7 | Checking the installation of the cassette paper feed clutch for the paper feed target Is the clutch installed properly? |
Go to step 8 | Reinstall it properly. |
| 8 | Checking the operation of the cassette paper feed clutch for the paper feed target Check the clutch operation with the diagnostic function. Does it make an operating sound (clutch connection sound)? |
Go to step 10 | Go to step 9 |
| 9 | Check the malfunctioning clutch for connection Are any of the connectors connecting the clutch not fully inserted? |
Fully insert the connectors | Replace the parts one by one.
|
| 10 | Check operation of the main unit motor Check operation of the corresponding main unit motors using the diagnostic function. Is there any abnormal noise? |
Replace the gear trains and the main unit motor. | Replace the MCU board |
