The office has opened in the West End and will be headed up by Xerox veteran Robin Carter-Browne, who has worked with the company since 1983.
Zerographic managing director Kevin Corbett said: "Zerographic has expanded rapidly both in sales growth and staff recruitment. Our future goals and expansion plans made it vital to establish a base in the capital. We are also able to better serve our existing London customers."
Carter-Browne will work alongside fellow long time Xerox names Bob Harness, who joined Xerox in 1984 and Murray Massie who has been with the company since 1989, as well as four new recruits who are expected to start throughout August.
The company has two existing offices, its Stafford headquarters and a site in Wakefield.
