Both the CS500 & CS600 come in standard and Pro models for a total of 4 possible configurations.  The standard models employ 600dpi optical resolution, while the Pro upgrades feature maximum optical resolution settings of up to 4800 dpi for superb accuracy and color reproduction.  The CS500 is designed for flexible document scanning while the CS600 scans thick, rigid material up to 0.8" thick. Both series enable sharp, accurate scanning of color photographs, graphics, and detailed architectural drawings.  In addition, both models come with standard Scanning Master 21+ driver software, enabling users to combine any CS-series scanner with a large-format color printer to create a multi-functional printing/copying system.
