Troubleshooting. Jam Code: 20-01, 20-02
Contents
| JAM type | Misfeed at vertical transport section |
| JAM code | 20-01, 20-02 |
| Detection timing | 20-01 The registration sensor (PS1) is not unblocked even after the lapse of a given period of time after the paper has turned ON the tray 2 vertical transport sensor (PS19). |
| 20-02 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. |
