The RICOH IS450DE scanner incorporates VRS (virtual rescan technology) which eliminates the need for rescanning by intelligently monitoring image quality at the time of scanning. The Ricoh IS450DE VRS scanner removes the need for time consuming pre-scan document sorting and allows the operator to easily adjust scanner settings on the fly. In addition, VRS increases post processing recognition accuracy and reduces image storage requirements. The Ricoh IS450DE VRS scanner supports industry standard interfaces ISIS, TWAIN, and Image Controls.
