JAM type | Misfeed at vertical transport section | |
JAM code | 20-02 | |
Detection timing | For paper fed from the tray 2, tray 3, tray 4 or LCT, 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. | |
Misfeed processing location | Right door | |
