| JAM type | Misfeed at 2nd transfer section | |
| JAM code | 30-01, 30-03 | |
| JAM detection timing | 30-01: The registration sensor (PS9) is not turned OFF (unblocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON (blocked) PS9. | |
| 30-03: The leading edge of the paper is not turned ON (unblocked) the paper exit sensor (PS13) even after the lapse of a given period of time after a paper feed starts to feed paper. | ||
| – Paper jam of a sheet of paper left at the 2nd transfer section results, if the registration sensor (PS9) is turned ON (blocked) when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | ||
| – Paper jam of a sheet of paper left at the 2nd transfer section results, if the fusing loop sensor (PS10) is turned ON (blocked) when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | ||
| – Paper jam of a sheet of paper left at the 2nd transfer section results, if a sheet of paper is determined to exist at a position detected when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | ||
