How Can We Help?
20-02 (bizhub 558/458)
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 |
| Relevant parts | • Transport motor (M1) • Tray 2 vertical transport motor (M23) • Tray 2 vertical transport clutch (CL2) • Registration clutch (CL4) • Registration sensor 1 (PS1) • Registration sensor 2 (PS72) (bizhub 558) • Tray 2 vertical transport sensor (PS19) • Expansion control board (EXCB) • Front side board (FRB) • MFP board (MFPB) |
