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 | Check the operation of the Paper Tray Post-Pickup Sensor Check the operation of the Paper Tray Post-Pickup Sensor 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 Tray Post-Pickup Sensor for installation, dirt, and connector connection Is the Paper Tray Post-Pickup Sensor installed improperly? Is there dirt on the sensor? Is the connector not fully inserted? |
Clean the sensor surface, or fully insert the connector. | Replace the sensor |
| 7 | Check the operation of the Pre-Registration Sensor Check the operation of the Pre-Registration Sensor with the diagnostic function. Does the signal change between when the paper is placed and when it is not? |
Go to step 9 | Go to step 8 |
| 8 | Check the Pre-Registration Sensor for installation, dirt, and connector connection Is the Resist Sensor installed improperly? Is there dirt on the sensor? Is the connector not fully inserted? |
Clean the sensor surface, or fully insert the connector. | Replace the sensor |
| 9 | Check the clutch installation Is the Paper Tray Pickup Clutch, PF Clutch 1, PF Clutch 2 installed properly? |
Go to step 10 | Reinstall it properly. |
| 10 | Check Paper Tray Pickup Clutch Checking the operation of the Paper Tray Pickup Clutch with the diagnostic function Does it make an operating sound (clutch connection sound)? |
Go to step 11 | Go to step 12 |
| 11 | Check the PF Clutch 1, PF Clutch 2 Check the clutch operation with the diagnostic function. Does it make an operating sound (clutch connection sound)? |
Go to step 13 | Go to step 12 |
| 12 | 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.
|
| 13 | Check operation of the main unit motor Check the operation of the corresponding Main Unit Motor with the diagnostic function. Is there any abnormal noise? |
Replace the gear trains or the Main Unit Motor. | Replace the MCU board |
