| JAM type | Misfeed at tray 3/4 intermediate transport roller section | |
| JAM code | 17-40, 17-41 | |
| JAM detection timing | 17-40 | LCC vertical transport sensor (PS28) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the tray 4 paper feed sensor (PS26). |
| 17-41 | The tray 2 vertical transport sensor (PS12) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the LCC vertical transport sensor (PS28). | |
| – | Paper jam of a sheet of paper left at the tray 3/4 intermediate transport roller section results, if the tray LCC vertical transport sensor (PS28) 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 3/4 intermediate transport roller 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 bottom door -Tray 3/4 horizontal transport unit | |
| Relevant parts | -LCC vertical transport motor (M26) -LCC transport motor (M25) -Tray 2 vertical transport motor (M7) -Tray 4 paper feed clutch (CL7) -LCC Vertical transport sensor (PS28) -Tray 4 paper feed sensor (PS26) -Tray 2 vertical transport sensor (PS12) -Paper feed/transport drive board (PFTDB) -Base board (BASEB) | |
