Troubleshooting. Jam Codes: 11-01, 11-02, 11-04, 11-05, 11-40
Contents
| JAM type | Misfeed at tray 1 paper feed section |
| JAM code | 11-01, 11-02, 11-04, 11-05, 11-40 |
| JAM detection timing | 11-01 After the tray 1 starts to feed paper, the registration sensor/1 (PS1) is not turned ON (unblocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON the tray 1 paper feed sensor (PS23). |
| 11-02 For paper fed from the tray 1, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop. |
|
| 11-04 The leading edge of the paper is not turned ON (unblocked) the registration sensor/2 (PS72) even after the lapse of a given period of time after the tray 1 starts to feed paper. |
|
| 11-05 The leading edge of the paper is not turned ON the tray 1 paper feed sensor (PS23) even after the lapse of a given period of time after the tray 1 starts to feed paper. |
|
| 11-40 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 paper feed section results, if the tray 1 paper feed sensor (PS23) is turned ON when operation stops due to the tray 1 FD size error. | |
| Misfeed processing location | • Right door • Tray 1 |
| Relevant parts | • Paper feed motor (M22) • Registration motor (M24) • Registration sensor/1 (PS1) • Tray 1 paper feed sensor (PS23) • Registration sensor/2 (PS72) • Base board (BASEB) |
