Abstract

Image throughput of a digital scanner equipped with a Universal Document Handler (UDH) is limited by scanning the document followed by retracing the scan carriage to the start of the scan position for the next scan. A one direction only scanner must retrace the moving carriage to the start-of-scan position after each scan. Although generally accomplished with an increase of carriage speed from scan speed, the electronic controls and hardware costs associated with reducing the time to an equivalent to document exchange time is high.
