Manual Feed Tray Paper Take-Up Mechanism • The Manual Feed Tray consists of a Paper Take-Up Roll, Paper Lifting Plate, and the Manual Feed Paper Take-Up Solenoid (SL1). • When the Manual Feed Paper Take-Up Solenoid (SL1) is energized, the cam turns. At the same time, the Paper Lifting Plate raises the tray and the paper on the tray is taken up by the Paper Take-Up Roll and fed into the printer.

  • Page 72: Lower Feeder Unit (Option)

    10-2. Lower Feeder Unit (Option) Paper Take-Up Mechanism • Since there is no drive motor installed, the drive for paper take-up and transport (supplied from M1) is transmitted through a drive coupling gear from the printer. • The same paper take-up mechanism is employed as that of the Multi-Purpose Tray, except that paper separator fingers are used, instead of the separator roll with a torque limiter, for paper separation.

  • Page 73: 11. Other Mechanisms

    11. OTHER MECHANISMS 11-1. Duplex Unit (Option) Drive • The drive for the Duplex Unit works as follows. The paper having a printed image on its one side is temporarily fed toward the Exit Tray and, as soon as the trailing edge of the paper moves past the guide plate before the Exit Roller, the Exit Roller is turned back- ward so that the paper is fed into the Duplex Unit.
