In October 1966 started the production of the Xerox 660 desktop copier, which was a improved version of Xerox 813. To make a copy, you entered how many copies you wanted, and then fed the original into the machine. The original came out in a slot in front of the machine, and the copies came out of a slot right beneath where the original came out. Obviously one couldn't make copies from a book with this machine.
The paper path inside the copier was quite simple. When the paper left the paper tray, a “gripper bar” with two clips opened and grabbed the paper and transported it under the drum, and through the fuser. The fuser unit was not a heat roller, but a heater lamp, and the paper passed under this heating lamp, in order for the toner to melt into the paper.
Toner and drums were tested to ensure manufacturing quality, in the test facility at Welwyn Garden City. In this photo you can see 3600, 4000, 7000 and 660 copiers.
