The Visioneer 7800 scanner is only 1.7 inches tall and weighs less than 4 pounds, fits neatly on a desk and is small enough to easily tuck away when not in use. The 7800 produces clear and sharp scans of any document in color or black and white. TWAIN driver technology quickly delivers scanned images to your computer while applying filters such as auto color detection and color matching, to ensure your scans are perfect.
