| JAM type | Misfeed at 2nd transfer section | |
| JAM code | 30-03 | |
| JAM detection timing | • The paper exit sensor (PS39) is not turned ON (unblocked) even after the set period of time has elapsed after the registration sensor (PS38) turns ON (unblocked) by a paper. • The fusing loop sensor/Fr (PS41) or fusing loop sensor/Rr (PS42) is not turned ON (unblocked) even after the lapse of a given period of time after the paper has turned ON (unblocked) registration sensor (PS38). | |
| – | Paper jam of a sheet of paper left at the 2nd transfer section results, if the registration sensor (PS38) is turned ON (unblocked) 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 OHP sensor (PS40) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | |
| – | When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the 2nd transfer section results, if the registration sensor (PS38) or paper exit sensor (PS39) is turned from OFF (unblocked) to ON (blocked). | |
