Scanner Assembly Functions Document originals can be placed on the scanner document glass (platen). In this mode of operation the original is stationary and the scanhead moves. Document Glass or Platen: The scanner platen is used for copying or scanning original documents and images. The platen functions well for media outside the operating range of the DADF (16 lb.-32 lb.), fragile or damaged originals, photographs, or large (or bound) items such as books or periodicals. scanhead and Lamp: The Flatbed portion of the IIT contains a moveable scanhead that includes the CCD imaging board, main control board, drive motor, and lamp assembly. The lamps are Cold Cathode Flourescent Lamps (same as the lamps in the DADF). CVT Window: This portion of the platen is a part of the DADF media path. The principal function of this window is to allow the lower scanhead to image the first side of an original being fed through the DADF. IIT Connector: An electrical connection on the rear of the Flatbed portion of the IIT connects to a receptacle on the IOT completing the signal path for image data from the IIT, power to the IIT, and system communications between the three components. Control Panel: The control panel is the user interface with the system. Theory of Operation 2-7
