When the paper feed signal is received by the Bypass Feed Tray, the Bypass Bottom plate is lifted up, and then the Bypass Feed Clutch is turned on to rotate the Bypass Feed Roller.
Only the sheet on the top in the Bypass Feed Tray is fed out by the Friction pad. Once the paper is fed out, the Duplex Exit Clutch is turned on to transport the paper to the same transport path as the path used for the paper from the Paper Feed Tray. When the paper fed into the machine activates the Registration Sensor, the Bypass Feed Clutch is turned off. Once the toner pattern formed on the transfer belt is moved to the right position, the Registration Clutch is turned on to transport the paper to the Image Transfer Unit.
