Troubleshooting. Jam Code: 10-01, 10-02, 10-10, 10-40
Contents
| JAM type | Manual bypass feed section |
| JAM code | 10-01, 10-02, 10-10, 10-40 |
| Detection timing | 10-01 The leading edge of the paper does not turn ON the tray 1 vertical transport sensor (PS4) even after the lapse of a given period of time after the manual bypass starts to feed paper. |
| 10-02 For paper fed from the manual bypass, 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. |
|
| 10-10 • The bypass paper limit sensor (PS35) is not blocked after the lapse of a predetermined period of time after the paper lifting plate is started to be raised from the standby position to the paper feed position. • For paper fed from the manual bypass tray, the bypass paper lower sensor (PS36) is not blocked after the lapse of a predetermined period of time after the paper lifting plate is started to be lowered from the paper feed position to the standby position. |
|
| 10-40 For paper fed from the manual bypass, 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, the tray 1 vertical transport sensor (PS4) is turned 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) • Bypass upper limit sensor (PS35) • Bypass lower limit sensor (PS36) • Paper feed/transport drive board (PFTDB) • Printer control board (PRCB) |
