The paper tray has a little slot in the left hand side that a black
plastic "finger" sticks down through when there is no paper in the
tray to block the slot. I'm sure it would be easy to just use that
black plastic finger rocker-switch to drive a little battery-and-buzzer
combination that you could get from Radio Shack....seems like about
the easiest way...
