The AV8350 is a high-speed and high-performance scanner capable of processing A3 sized paper. It is capable of performing duplex scanning and has a USB 2.0 interface about 40 times faster than the older USB 1.1 interface. If large amounts of paper need to be processed, purchase the optional auto-paper feeder which accommodates a batch of 100-pages document to be scanned continually at one time. At a scanning rate of 40 pages per minute in simplex mode and 80 images per minute in duplex mode, the AV8350 is truly a scanning powerhouse to meet all your scanning needs for A3-sized documents.
