Detection timing

Type	Description
Detection of misfeed at 2nd image transfer section	• A sheet of paper does not turn OFF the sensor in front of tim. roller (PS1) after a predetermined period of time has elapsed since the sheet has turned ON the PS1.
	• A sheet of paper does not turned ON the paper exit sensor (PS2) after a predetermined period of time has elapsed since the sheet has turned ON the sensor in front of tim. roller (PS1).
Detection of paper left in 2nd image transfer section	• The sensor in front of tim. roller (PS1) is turned ON when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset.
2nd image transfer section loop registration reversing jam	• For paper fed from the tray, 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.
