Xerox Bulgaria Ltd. was established in 1968 as a representative office of Rank Xerox. The Xerox dealers network, which covers the territory of Bulgaria, was established in 1991. The range of Xerox services includes: research of customer needs for the most appropriate document-processing equipment; delivery and installation of the equipment; training of operators, and maintenance through Xerox’s service network. The history of Xerox dates back to 1947, when the Haloid Company got a contract to develop and present a copy machine based on Chester Carlson’s xerographic invention.
