Duplex scanning

Duplex scanning

Duplex scanning is a feature of computer scanners and multifunction printers (MFPs) that allows the automatic scanning of a sheet of paper on both sides. Devices without this capability can only scan a single side of a sheet of paper at a time.

In general, duplex scanning is achieved on multifunction printers using a Reversing Automatic Document Feeder (RADF). Duplex scanning is achieved on computer scanners by either RADF or by single pass duplex scanning using two cameras; one for the front side of the document and one for the back side of the document.

On MFPs, it is common to find duplex scanning on devices that also have duplex printing capabilities.
