17-20 (bizhub 958/808)
Contents
| JAM type | Misfeed at LCT transport section (When LU-205 or LU303 is installed) | |
| JAM code | 17-20 | |
| JAM detection timing | The tray 2 vertical transport sensor (PS12) is not turned ON even after the set period of time has elapsed after the LU paper feed sensor (PS3) turns ON by a paper. | |
| – | Paper jam of a sheet of paper left at the LCT transport section results, if the LU paper feed sensor (PS3) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | |
| Misfeed processing location | Lower right door | |
| Relevant parts | • LU transport motor (M3) • LU paper feed sensor (PS3) • Tray 2 vertical transport sensor (PS12) • LU drive board (LUDB) • Paper feed/transport drive board (PFTDB) |
