| JAM type | Misfeed at external LCT paper feed section (When LU-205 or LU-303 is installed) | |
| JAM code | 15-01, 15-40 | |
| JAM detection timing | 15-01: The leading edge of the paper is not turned ON the LU paper feed sensor (PS3) even after the lapse of a given period of time after the external LCT starts to feed paper. | |
| 15-40: For paper fed from the external LCT, 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 external LCT paper feed 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. | ||
| Paper jam of a sheet of paper left at the external LCT paper feed section results, if a sheet of paper is determined to exist at a position detected when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | ||
| Misfeed processing location | Right door | |
| Relevant parts | -LU paper feed motor (M2) -LU paper feed sensor (PS3) -LU drive board (LUDB) -Base board (BASEB) -PC control board (PCCB) |
