Xerox®, whose name has been a synonym for "to copy," remains a leading seller of copiers and printers, from basic black-and-white output to high-end colour systems. These days, Xerox® makes most of its revenue from its post-sale services such as document management, maintenance, supplies and paper, and financing. Xerox® also sells software for automating and integrating print jobs from start to finish. Its products are used in offices of large and small- and medium-sized businesses and in production plants of commercial printing companies.
