xer-, xero-, xir- +

1. A trademark for a photocopying or printing process that uses xerography.
2. A global company dedicated to providing office solutions. Xerox offers digital copiers, fax machines, printers, scanners, and multi-function devices.

The Xerox Corporation is considered to be the world's largest document-management company, providing the industry's broadest range of color and black-and-white printers, multifunction systems, copiers, digital production printing presses, and related consulting services and supplies.

The company is so identified with its product that the term "Xerox machine" is often used to refer to xerographic duplicators produced by other companies.

The verb term "xeroxing" has become synonymous with "copying"; however, the company does not condone nor in any way approve of the uses of its trademark name as a verb, adjective, nor noun.
