The paper feed clutch employs the mechanical spring clutch. The paper feed operation is controlled by the paper feed roller clutch and the paper feed roller clutch solenoid. The paper is passed to the transfer section by the paper feed roller. Paper feed, paper transport section (1) Outline The paper feed tray contains about 200 (250) sheets of paper.
