Interesting
copies.
A photocopier (or copier)
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 the 1960s, and over the following 20 years 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... |
