There are two kinds of document feeders capable of two-sided (duplex) scanning: a reversing automatic document feeder or RADF scans one side of a page, then flips it and scans the other side. A duplexing automatic document feeder or DADF scans both sides in one pass.

An automatic document feeder (ADF) is a feature in printers, photocopiers, fax machines or scanners wherein a stack of paper put into the machine and is then automatically fed through it, allowing the user to print, scan or copy without having to manually place each page into the machine.

The Automatic Document Feeder (ADF) on the printer does not pick up paper. The procedures in this document can help by showing you how to check the paper and clean the ADF mechanism.

Printers, copiers or fax machines equipped with an automatic document feeder optimize your paperwork and bookkeeping processes. However, should you have longer documents, with 10, 50, or even hundreds of pages, standing at the copy machine and manually inserting each page one by one is quite time-consuming.

Because legal documents are the same width as letter-sized paper, most scanners can scan them. In most cases, you simply have to put the paper into the scanner and scan it as you would a letter-sized document. The scanner should automatically detect the size of the document and scan it at its full size.

Platen may also refer to a typewriter roller which friction-feeds paper into position below the typebars or print head, it can refer to the glass surface of a copier, or it can refer to the rotating disk used to polish semiconductor wafers.
