Abstract
A one-arm sensing lever having a sensing cam and carrying a permanent magnet faces a spring-biased, two-arm rocking lever across the paper-feed path of a printer; in the absence of paper, the cam drops into the feed path and the magnet is now capable of attracting one arm of the rocking lever so that its other arm operates a switch.
