Reverse automatic document feeder A scanner with a duplexing automatic document feeder A Konica Minolta photocopier with an automatic document feeder in use. In multifunction or all-in-one printers, fax machines, photocopiers and scanners, an automatic document feeder or ADF is a feature which takes several pages and feeds the paper one page at a time into a scanner or copier, [1] allowing the ...
An All-in-one is a small desktop unit, designed for home or home-office use. These devices focus on scan and print functionality for home use, and may come with bundled software for organising photos, simple OCR and other uses of interest to a home user.

Xerox was founded in 1906 in Rochester, New York, as the Haloid Photographic Company. [12] It manufactured photographic paper and equipment. In 1938, Chester Carlson, a physicist working independently, invented a process for printing images using an electrically charged photoconductor-coated metal plate [13] and dry powder "toner".
A Xerox digital photocopier in 2010. A photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply.
The controller and scanner were common to both models, but the Model 90 used a different print engine based on one developed for the previously announced Xerox 4090 printer. The original DocuTech Production Publisher was capable of scanning and then printing black-and-white pages at up to 135 pages per minutes (for letter or A4 sizes) with an ...
One of the two copiers that were present that day caught fire. [ 1 ] The 914 was one of the most successful Xerox products ever, and was a significant component of Xerox's revenues in the mid-1960s, with one author estimating that the machine accounted for two thirds of the company's revenue in 1965, with income generated of $243M.
In later years it would be combined with copier equipment to create the hybrid machines we have today that copy, scan and fax. Some of the lesser known capabilities of the Xerox fax technologies included their Ethernet enabled Fax Services on their 8000 workstations in the early 1980s.
Document scanners have document feeders, usually larger than those sometimes found on copiers or all-purpose scanners. Scans are made at high speed, from 20 up to 420 pages per minute, often in grayscale, although many scanners support color. Many scanners can scan both sides of double-sided originals (duplex operation).
