In October 1963 started the production of the Xerox 813 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 three grippers on two bars run by a chain 180 degrees apart, 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.
