Xerox's first foray into duplicating, as distinct from copying, was with the Xerox 2400, introduced in 1966. The model number denoted the number of prints produced in an hour. Although not as fast as offset printing, this machine introduced the industry's first automatic document feeder, paper slitter and perforator, and collator (sorter). This product was soon sped up by fifty percent to become the Xerox 3600 Duplicator.[citation needed]
