PhotoCopier

A photocopier - is a machine that makes paper copies of documents and other illustration images fast and economically. Most current photocopiers use a technology called xerography, a dry process using heat. Copiers can also use other output technologies such as ink jet.

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 occurrence of its use is one of the reasons that prevented the progress of the paperless office heralded early in the digital revolution.

Photocopying is usually used in business, education, and government. There have been many forecasts that photocopiers will eventually become out of date as information people continue to increase their digital document creation and distribution, and rely less on distributing actual pieces of paper.
