12-40 (bizhub 958/808)
Contents
| JAM type | Misfeed at tray 2 feed section |
| JAM code | 12-01 |
| JAM detection timing | For paper fed from the tray 2, the image write start signal permit continues to be disabled for a predetermined period of time after the timing of the image write start signal output. |
| – | Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. |
| – | When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned from OFF to ON. |
| Misfeed processing location | Lower right door |
| Relevant parts | • Paper feed motor (M22) • Tray 2 paper feed clutch (CL2) • Tray 2 vertical transport sensor (PS12) • Tray 2 paper feed sensor (PS13) • Paper feed/transport drive board (PFTDB) • MFP board (MFPB) |
