Turns out, that our office Xerox machine had a fairly significant amount of
distortion that wasn't noticeable on a page of text but managed to turn
circles into ovals. To save five bucks, I had created a series of
non-workable, interlocking cams.

I believe copy machines are required to slightly distort the image. It prevents
someone from copying paper money and then running the copy through a change
machine.
