A photocopier (also known as a copier or copy machine) is a machine that makes paper copies of documents and other visual images quickly and cheaply.
Most current photocopiers use a technology called xerography, a dry process using heat. (Copiers can also use other output technologies such as ink jet, but xerography is standard for office copying.)________
Xerographic office photocopying was introduced by Xerox in 1949, and it gradually replaced copies made by Verifax, Photostat, carbon paper, mimeograph machines, and other duplicating machines.
The prevalence of its use is one of the factors that prevented the development of the paperless office heralded early in the digital revolution.________
Photocopying is widely used in business, education, and government.
There have been many predictions that photocopiers will eventually become obsolete as information workers continue to increase their digital document creation and distribution, and rely less on distributing actual pieces of paper.________
