A generic name for the machines which were once so strongly associated with Xerox that their name was sometimes used as a generic term for the device, and as a verb meaning to make copies on such a device. These days, many other companies make copy machines. Xerox still makes copy machines too, including the DocuTech line of high-speed duplicators that make up to 135 copies per minute. These machines store book-sized print jobs in memory and print the pages of such jobs in order, to avoid the need for collation.

Also called copier, photocopier.
