The scanning glass is protected by the use of various sensors that detect stapled pages and automatically interrupt the scan process. It is also equipped with ultrasonic multi-feed detection and an innovative self-cleaning function that removes dust from the scanning glass to ensure consistently high image quality. The DocuMate 4790 has a convenient clamshell design that allows direct and straightforward access to the entire paper path so a user can clear paper jams clean the unit or replace the rollers easily without having to call a service technician. A pre-scan imprinter is also available and is supported through the included TWAIN and ISIS drivers.The Xerox® DocuMate 4790 provides both high quality image enhancement and increased productivity with Kofax® VRS™ Professional AIPEEBC for auto-everything scanning.TWAIN and ISIS drivers are included to ensure compatibility with document management software and your capture applications. The DocuMate 4790 is powered by Visioneer OneTouch scanning technology for simplifying scan jobs and workflows.

We wouldn’t have it any other way. The Xerox® DocuMate® 4790 is the ideal scanner for both large-volume and distributed scanning environments. It has a duty cycle of up to 10 000 sheets per day and has been engineered with innovative features for easy operation and productive batch scanning including stapled documents ultrasonic double feed detection and support for long document scanning.A highly reliable and compact document scanner the DocuMate 4790 scans up to 90 ppm and 180 ipm and includes a 200-page Automatic Document Feeder that accepts up to A3 (11” x 17”) size documents and can handle almost any mix of paper in various sizes and thicknesses. Its unique paper feed mechanism minimises the possibility of damaging important documents and ensures precise feeding to make your work flow even more efficient.The roller on the DocuMate 4790 is designed for efficiency by separating itself from the page each time a sheet is fed reducing the likelihood of drag and double feeds and improving the life of the roller. A separate double feed prevention roller applies controlling pressure when paper ‘sliding’ (caused by buildup of toner or carbon on the rollers) is detected.
