10.10.2 Paper Path of DADF (Duplex)

After scanning a document is completed and the rear edge of the document is passed through the Transport
Roll, switch the position of the Pressure Plate to above. Then, the Exit Roll is reversed by the reverse drive of
the DADF Motor, and the document is nipped into the DADF. The document is reversed at this time. When the
position of the Pressure Plate is switched, the gear to drive the Transfer Roll is switched, so the rotation is in a
positive manner although the DADF Motor rotates in a negative manner. When the document is fed near side
of the Take away Roll, switch the position of the Pressure Plate to below to make the DADF Motor return to
the positive rotation drive, and the document is fed to the Scanner Home Position (CVT Position) by the
torque from the Transport Roll. The document scanned at the CVT Position is fed to the Document Output
Tray of the DADF by the Transport Roll and the Exit Roll.
