20-02 (bizhub 958/808)
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 LU-205/LU-303, 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 | • Manual bypass tray door • Lower right door |
| Relevant parts | • Tray 1 vertical transport motor (M5) • Tray 2 vertical transport motor (M7) • Tray 1 vertical transport sensor (PS4) • Tray 2 vertical transport sensor (PS12) • Registration sensor (PS38) • OHP sensor (PS40) • Paper feed/transport drive board (PFTDB) • MFP board (MFPB) |
