| JAM type | Misfeed at vertical transport section (tray 3) | ||
| JAM code | 20-21 | ||
| Detection timing | <When PC-110 or PC-210 is installed> The tray 2 vertical transport sensor (PS19) is not turned ON even after the lapse of a given period of time after the tray 3 vertical transport sensor (PS113) has been blocked by a paper. | ||
| <When PC-410 is installed> The tray 2 vertical transport sensor (PS19) is not turned ON even after the lapse of a given period of time after the vertical transport sensor (PS133) has been blocked by a paper. | |||
| – | 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 vertical transport section. | ||
| Misfeed processing location | Right door | ||
