| JAM type | Misfeed at DF transport section | |
| JAM code | 66-03, 66-13, 66-23, 66-33 | |
| JAM detection timing | 66-03 | The after separate sensor (PS4) is not turned OFF even after the lapse of a given period of time after PS4 has turned ON. |
| 66-13 | The document registration sensor (PS5) is not turned ON even after the lapse of a given period of time after the after separate sensor (PS4) has turned ON. | |
| 66-23 | The document registration sensor (PS5) is not turned OFF even after the lapse of a given period of time after PS5 has turned ON. | |
| 66-33 | The document reading sensor (PS6) is not turned ON after a lapse of a given time after the document registration sensor (PS5) is turned ON. | |
| – | Paper jam of a sheet of paper left at the DF transfer section results, if the document registration sensor (PS5) is turned ON when the main power switch is turned ON, a DF left cover is opened and closed, or a misfeed or malfunction is reset. | |
