| JAM type | Misfeed at tray 4 paper feed section | |
| JAM code | 14-01, 14-40 | |
| JAM detection timing | 14-01 | The leading edge of the paper is not turned ON the tray 4 paper feed sensor (PS26) even after the lapse of a given period of time after the tray 4 starts to feed paper. |
| 14-40 | For paper fed from the tray 4, the image write start signal permit continues to be disabled for a predetermined period of time after the timing of the image write start signal output. | |
| – | Paper jam of a sheet left at the tray 4 paper feed section results, if the tray4 paper feed sensor (PS26) is turned ON 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 tray 4 paper feed 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 | Tray 4 -Right bottom door | |
| Relevant parts | -LCC transport motor (M25) -Tray 4 paper feed clutch (CL7) -Tray 4 paper feed sensor (PS26) -Paper feed/transport drive board (PFTDB) -Base board (BASEB) | |
