How exactly is it jamming? Is something (like the wires) in the way of the
coins dropping through? Is the acceptor positioned in the frame correctly? Does the acceptor reject good
coins?
I used to have an acceptor in the same bay jam often. I finally realized it was every Tuesday, so I checked the video. It was the same people about the same time of day every time, so I went and hung out to find out why. These same idiots were putting nickels, dimes, and pennies into it, filling the reject chute, then they would leave or move to a different bay, then someone else would come along and lose their money in it and dig out the change they could get to. So I would never have figured it out if I hadn't seen it on video.
