Canon plans to axe 400 jobs in a redundancy programme designed to trim the Japanese group's UK workforce to 2,600.
Most of the redundancies will be at the company's head office at Woodhatch near Reigate. Regional sales jobs are also likely to go.
There will be a three-month restructuring of the group's telecoms and business operations, which provides internet, network and computer solutions as well as photocopiers.
UK managing director Lars-Erik Kennbert explained that the cuts were in response to depressed demand for computers and technology.
"The decision is tough but necessary," he said. "We carried out an analysis of staffing requirements on present and predicted future requirements."
