Manual bypass feed section
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. |
