High-end color photocopiers capable of heavy-duty handling cycles and large-format printing remain a costly option found primarily in print and design shops.Ĭhester Carlson, the inventor of photocopying, was originally a patent attorney, as well as a part-time researcher and inventor. Low-end machines that can copy and print in color have increasingly dominated the home-office market as their prices fell steadily during the 1990s. ![]() During the 1980s, a convergence began in some high-end machines towards what came to be called a multi-function printer: a device that combined the roles of a photocopier, a fax machine, a scanner, and a computer network-connected printer. While there have been predictions that photocopiers will eventually become obsolete as information workers increase their use of digital document creation, storage, and distribution and rely less on distributing actual pieces of paper, as of 2015, photocopiers continue to be widely used. ![]() Photocopying is widely used in the business, education, and government sectors. Copiers can also use other technologies, such as inkjet, but xerography is standard for office copying.Ĭommercial xerographic office photocopying was introduced by Xerox in 1959, and it gradually replaced copies made by Verifax, Photostat, carbon paper, mimeograph machines, and other duplicating machines. The toner is then fused onto the paper using heat, pressure, or a combination of both. Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. ![]() 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.
