10-40 (bizhub 958/808)
Contents
| JAM type | Misfeed at manual bypass feed section |
| JAM code | 10-40 |
| JAM detection timing | For paper fed from the manual bypass tray, 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. |
| – | 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 manual bypass feed section results, if the 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 | • Bypass paper feed motor (M27) • Tray 1 vertical transport sensor (PS4) • Paper feed/transport drive board (PFTDB) • MFP board (MFPB) |
