Detection timing

Type	Description
Detection of misfeed at vertical transport section	• The leading edge of the paper does not turn ON the sensor in front of tim. roller (PS23) even after the lapse of a given period of time after the paper has blocked the paper feed tray 2 vertical transport sensor (PS16).
	• The paper feed tray 2 vertical transport sensor (PS16) is not unblocked even after the lapse of a given period of time after the paper has blocked the PS16.
Vertical transport section loop registration reversing jam	• For paper fed from the tray 2, loop forming has not been complete before a sheet enters the timing roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop.
