11-40 (bizhub 958/808)
Contents
| JAM type | Misfeed at tray 1 feed section |
| JAM code | 11-01 |
| JAM detection timing | For paper fed from the tray 1, 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 1 feed section results, if the tray 1 vertical transport sensor (PS4) 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 1 feed section results, if the tray 1 vertical transport sensor (PS4) is turned from OFF to ON while the tray 1 paper feed sensor (PS5) is OFF. |
| Misfeed processing location | Manual bypass tray door |
| Relevant parts | • Paper feed motor (M22) • Tray 1 paper feed clutch (CL1) • Tray 1 vertical transport sensor (PS4) • Tray 1 paper feed sensor (PS5) • Paper feed/transport drive board (PFTDB) • MFP board (MFPB) |
