was sold as a platemaker for the Addressograph-Multigraph Multilith 1250 and related sheet-fed offset printing presses in the offset lithography market. It was little more than a high quality, commercially available plate camera mounted as a horizontal rostrum camera, complete with photo-flood lighting and timer. The glass film/plate had been replaced with a selenium-coated aluminum plate. Clever electrics turned this into a quick-developing and reusable substitute for film. A skilled user could produce fast, paper and metal printing plates of a higher quality than almost any other method. Having started as a supplier to the offset lithography duplicating industry, Xerox now set its sights on capturing some of offset's market share. The 1385 was followed by the first automatic xerographic printer, the Copyflo, in 1955. The Copyflo was a large microfilm printer that could produce positive prints on roll paper from any type of microfilm negative. Following the Copyflo, the process was scaled down to produce the 1824 microfilm printer. At about half the size and weight, this still sizable machine printed onto hand-fed, cut-sheet paper which was pulled through the process by one of two gripper bars. A scaled-down version of this gripper feed system was to become the basis for the 813 desktop copier. Xerox 914 The company came to prominence in 1959 with the introduction of the Xerox 914, "the most successful single product of all time." The 914, the first plain paper photocopier, was developed by Carlson and John H. Dessauer; it was so popular that by the end of 1961 Xerox had almost $60 million in revenue. The product was sold by an innovative ad campaign showing that even monkeys could make copies at the touch of a button - simplicity would become the foundation of Xerox products and user interfaces. Revenues leaped to over $500 million by 1965. Xeronic Computer Printer In 1956, Haloid formed a joint venture in the UK with Rank Organisation whose Rank Precision Industries Ltd. subsidiary was charged with anglicising the US products. Rank's Precision Industries went on to develop the Xeronic computer printer and Rank Data Systems Ltd was set up to bring the product to market. It used cathode ray tubes to generate the characters and forms that could be overlaid from microfilm images. Initially, they planned for the Ferranti and AEI computer companies to sell the Xeronic as an on-line peripheral, but due to interface problems, Rank
