Troubleshooting
| Step | Check and measure | Yes | No |
|---|---|---|---|
| 1 | Visually check the FFCs of the ADF/SCN Unit. Check the FFCs (x2) in ADF/SCN to make sure that it is not inserted obliquely, disconnected, or damaged. |
Go to step 2 | Correctly insert the two FFCs. If FFC is damaged, replace the ADF/SCN Unit. (Replace the unit even if one of the two FFCs is damaged.) |
| 2 | Visually check the gear train parts. Check the gear train parts to make sure that there is no foreign object on or damage to them. |
Go to step 3 | Remove the foreign object. Replace the ADF/SCN Unit if the gear is damaged. |
| 3 | Replace the ADF/SCN Unit. Does the error occur after replacing the ADF/SCN Unit? |
Replace the Main Board Assy. (If the trouble is not resolved, contact the EPSON Service Department.) | End |
