  • Page 24: Document Pickup/Feed

    2. Technical Explanation Document Pickup/Feed Basic Operation After pressing the start key with a document placed on the Document supply tray, a document is picked up in the following procedure. ■ Pickup Operation The Pickup motor (M1) drives to lower the Pickup roller assembly through the Pickup clutch (CL1) and then the Pickup roller rotates to feed a document.

  • Page 25: Pickup Roller Assembly And Separation Roller

    2. Technical Explanation ■ Stream reading The stream reading starts when the leading edge of a document reaches the reading point and the read start signal is received from the host machine. "Stream reading" is a scan function which a document is scanned while feeding along the Document glass. The Scanner which is fixed under the Document glass reads the image.

  • Page 26: Document Reversing

    2. Technical Explanation Document Reversing Basic Operation There are two types of document reversal operation: one that is performed from the top to the reverse side of the document and the other that is performed from the reverse side to the top of the document. Since the basic operation methods are identical, only the reversal operation performed from the reverse side to the top is discussed below.
