When PC-116 or PC-216 is installed
Contents
| JAM type | Misfeed at vertical transport section (tray 3) (When PC-116 or PC-216 is installed) | |
| JAM code | 20-21 | |
| JAM detection timing | 20-21: The tray 2 vertical transport sensor (PS19) 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 3 vertical transport sensor (PS113). | |
| – | -: Paper jam of a sheet of paper left at the vertical transport 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 door | |
