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 | -External LCT (LU-205 or LU-303) -Right door | |
Relevant parts | -LU paper feed motor (M2) -LU paper feed sensor (PS3) -LU drive board (LUDB) -Paper feed/transport drive board (PFTDB) -Base board (BASEB) |
