JAM type | Misfeed at vertical transport section | |
JAM code | 20-01, 20-02, 20-04 | |
JAM detection timing | 20-01: The registration sensor/1 (PS1) is not turned ON (unblocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON the tray 2 vertical transport sensor (PS19). | |
20-02: For paper fed from the tray 2, 3 or 4, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop. | ||
20-04: The registration sensor/2 (PS72) 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 2 vertical transport sensor (PS19). | ||
