Troubleshooting
| Step | Confirmation points and methods | Page | YES | NO |
|---|---|---|---|---|
| 1 | Perform Rear AD Does the product recover from the failure? | End | Go to step 2 | |
| 2 | Replace the UPE Sensor (board) Does the product recover from the failure? | UPE Sensor | End | Go to step 3 |
| 3 | Replace the Paper Thickness Sensor Does the product recover from the failure? | Paper Thickness Sensor | End | Go to step 4 |
| 4 | Replace CR Unit (including PW Sensor) Does the product recover from the failure? | CR Unit | End | Go to step 5 |
| 5 | Replace Roll Paper Detection Sensor (side of roll paper that does not start paper feed) Does the product recover from the failure? | 1st Paper Feed Driven Release Sensor/1st Paper Path Paper Detection Sensor 2nd Paper Feed Driven Release Sensor/2nd Paper Path Paper Detection Sensor | End | Escalate to person in charge |
