Abstract
A dual mode document aperture imaging prevention system and document edge location system, using the same digital document imager, for imaging different sizes of moving document sheets, some of which may have punched notebook or binder holes or other apertures. Both a black or substantially light absorbing imaging background surface area and a white or substantially light reflective imaging background surface area are automatically selectably provided in the same document imaging station as document backing surfaces for the two respective functions. The dark imaging background is automatically provided to be illuminated and imaged for document edge detection, and the light imaging background may be selected to be automatically provided for illuminating and imaging the body of the document to prevent imaging any apertures of any apertured document sheets. The two different imaging backgrounds may be provided by automatically slightly rapidly shifting the imager's imaging position between the two adjacent imaging background areas, or by slightly sifting a backing baffle member having the two differently colored areas relative to a fixed position imager.
