In 1959, nobody really thought that Gutenberg's printing press needed to be improved on, except Xerox, which introduced the Xerox 914, the first plain paper, automatic copier the world had seen. Between 1959 and 1976, more than 200,000 914s were manufactured. When Xerox hired me in 1973 I was eventually trained to assemble and test these. They didn't have any circuit boards, all relays, timers and switches. They had a 'puffer' that shot a small stream of air to help remove the copy from the drum. They actually made a very sharp copy for back in those days. The lens was either made by Bausch & Lomb or Zeiss. Visit this link: https://www.youtube.com/watch?v=BmS0Jpo6dxQ
This was the first one to produce copies at 120 pages per minute. It was common to see 10-20 copies on them. These were made to military specs and the best ones made in those days. Later they made the 9700, the first high speed digital printer.
In 1966 the Beatles had landed; The Stones were rolling, and Dylan was crooning. Counter culture was groovy. But faster printing wasn't far out, it was already in the office where the squares were working. The Xerox 660 was the fastest table-top, plain-paper copier the company had put out to date. And it reflected the fast times the country was seeing, cranking out and out of sight 11 copies per minute.
This was the first generation of their duplicators. Here's the data I found on the very expensive programmer: The Burroughs 101P479 programmer is a fantastically rare Beam-X circuit which functions as the primary control and display unit in a Xerox 2400, the world's first high-volume photocopier. The 101P479 controls the number of copies being made, and calculates the billable cost on a sliding scale. The 101P479 dates from 1965, and is equipped with five Beam-X Switch magnetic beam switching tubes and several early transistors. https://www.youtube.com/watch?v=ExX3AUY-wSo
Times have changed and in a good way. This old beast had cascading developer that dropped toner mixed with developer across the drum, had a gear driven chain-bead mechanism that seldom worked for very long for toner reclaim, helix gears for the lamp scanner, a scan cam that moved the lamp, rotary cam that actuated switches paper feed timing, registration...all crammed into a tiny dark hole. This was one of the first copiers that offered two sided copies.
Xerox products did cost more but they are built to last for twenty years. They owned the market at first but faced increasing competition as technology changed. For the longest time all Xerox technicians had to wear dress suits to work. We looked great but it wasn't really practical but is was the image Xerox wanted to convey. Service techs flew first class to the national training center, stayed on campus, had free meals, etc. All sales reps trained there as well. One prerequisite to be a sales rep was a 4 year degree. How times have changed!
