| JAM type | Misfeed at tray 3 paper feed section (When PF-P20 or PF-P21 is installed) | |
| JAM code | 13-01, 13-40 | |
| JAM detection timing | 13-01: The leading edge of the paper is not turned ON (unblocked) the tray 3 transport sensor (PS6/3) even after the lapse of a given period of time after the tray 3 starts to feed paper. | |
| 13-40: For paper fed from the tray 3, 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 of paper left at the tray 3 paper feed section results, if the tray 3 transport sensor (PS6/3) 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 tray 3 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. | ||
