| JAM type | Misfeed at tray 1 feed section | |
| JAM code | 11-40 | |
| Detection timing | For paper fed from the tray1, 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. | |
| – | Tray 1 paper feed sensor (PS23) is turned ON when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset. | |
| – | In case paper position is detected as locating properly after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at tray 1 feed section. | |
| Misfeed processing location | -Right door -Tray 1 | |
| Relevant parts | -Paper feed motor (M22) -Registration motor (M24) -Tray 1 paper feed clutch (CL3) -Registration sensor (PS1) -Tray 1 paper feed sensor (PS23) -Front side board (FRB) -Expansion control board (EXCB) -Printer control board (PRCB) |
