| JAM type | Misfeed at fusing/paper exit section | |
| JAM code | 32-01, 32-05, 32-06, 32-30 | |
| JAM detection timing | 32-01: The leading edge of the paper is not turned ON (unblocked) the ADU paper passage sensor/1 (PS40) even after the lapse of a given period of time after the reverse sequence is started. | |
| 32-05: The paper exit sensor (PS3) is not turned OFF (blocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON (unblocked) PS3. | ||
| 32-06: The paper exit sensor (PS3) is not turned ON (unblocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON (unblocked) the fusing loop sensor (PS2). | ||
| 32-30: A trouble of the heating roller assy’s failure to turn has been detected during a print cycle. | ||
| Paper jam of a sheet of paper left at the paper exit section results, if the paper exit sensor (PS3) 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 paper exit 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. | ||
| Misfeed processing location | Right door | |
