It weighs approximately 650 pounds (294 kg) and measures 42" (107 cm) high × 46" (117 cm) wide × 45" (114 cm) deep. The machine was mechanically complex. It required a large technical support force, and had a tendency to catch fire when overheated. Because of the problem, the Xerox company provided a "scorch eliminator", which was actually a small fire extinguisher, along with the copier. Ralph Nader was among those to complain about the copier fires, reporting that the machine at his office in Washington had caught fire three times in four months. A 1967 article in The New Yorker by John Brooks detailed the relationship between the office secretary and the copier. A secretary he had interviewed for the piece said that a technical representative from Xerox had warned her "not to be afraid of the 914 because the machine would sense her fear and, like a mischievous child, misbehave." Despite these problems, the machine was regarded with affection by its operators, due to it being complex enough to be interesting to use, but without being so complex as to be beyond understanding. The pricing structure of the machine was designed to encourage customers to rent rather than buy: it could be rented in 1965 for $25 per month, plus 10 cents per copy. There was a meter, which the customer would read to fill out and mail a card to Xerox each month. Its purchase price was $27,500, which was established by the US Government, as they would not rent equipment. The customer also bought paper and toner (ink) at a cost of about 5 cents per copy. Sales The Xerox 914 was produced between 1960 and 1977. It was introduced to the public on September 16, 1959, in a demonstration at the Sherry-Netherland Hotel in New York, shown on live television. One of the two copiers that were present that day caught fire. The 914 was one of the most successful Xerox products ever, and was a significant component of Xerox's revenues in the mid-1960s, with one author estimating that the machine accounted for two thirds of the company's revenue in 1965, with income generated of $243M. The second television commercial produced by Xerox for the 914 featured a trained chimpanzee using the copier. The day after the commercial debuted, the company received calls from angry customers complaining of co-workers leaving bananas on the copier and
