Printers With Auto-Duplexing ADFs

An auto-duplexing printer automatically prints on both sides of the paper. Many all-in-one printers (AIOs) have an auto-duplexing feature along with an automatic document feeder (ADF), so multiple pages are fed into the printer at the same time. Here's what you need to know about printers with auto-duplexing ADFs.

Two Kinds of ADFs That Support Double-Sided Printing

ADFs are included with many types of printers and AIOs. They come in several sizes, accommodating between 15 and 25 pages to 35 or 50 pages and more.

There are two kinds of automatic document feeders that support double-sided printing. A reversing automatic document feeder (RADF) scans one side of a page, and then flips the page over and scans the other side. This happens automatically, without you having to participate.

A duplexing automatic document feeder (DADF) scans both sides of a page automatically in one pass, so DADFs are faster when you're printing two-sided documents. DADFs also cope better with thicker paper.

Both RADFs and DADFs are rated by the number of sides they can scan in a minute. This measurement is called images per minute (IPM).

Examples of AIOs With Auto-Duplexing and an ADF

If you have an all-in-one printer with auto-duplexing and an ADF, you can quickly print, scan, copy, or fax double-sided documents without flipping the pages and manually feeding them, which is a timesaver.

There's a range of printers that accommodate two-sided printing with automatic document feeding. Here are a few top-rated models.
