A unique feeding system and advanced sensor technology ensure that a wide range of mixed-paper-size batches or other challenging scan operations are handled with minimal operator intervention at maximum scanning speed-up to 75 pages per minute in simplex or 150 images per minute in duplex. Its ability to recognize and rotate text orientation, correct skewed images, enhance faint text, and adjust gamma settings allow the DR-7580 device to efficiently and accurately capture valuable information included on contracts and forms.
