20-02 (bizhub C658/C558/C458)
Contents
| JAM type | Misfeed at vertical transport section |
| JAM code | 20-02 |
| JAM 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 |
