Somewhat OT, I'm old enough to remember using a high-speed Kodak electrophotographic copier with a fancy finishing unit attached. The whole thing was about 20 feet long, and, like all electrophotographic copiers, it had to capture the image of the original for every copy made, so it had a mechanism that ran the original over and over the platen - it worked so fast that the flash lamp seemed almost like a strobe light.
