Theory of Operation 2-7
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.
