Staple sensing apparatus
in a finisher for finishing sets of copy sheets by stapling the sets into stapled booklets, staple sensing apparatus for sensing whether or not a staple has been properly driven, through the set of sheets. If a staple has been properly driven the legs of the staple effect an electrical continuity between staple clinchers. The electrical continuity is sensed and a first signal is produced indicative of a proper staple to permit continued operation of the finisher and electrographic apparatus to which it is attached. If an electrical discontinuity is sensed, a second signal is produced indicative of an improper staple and a display is actuated to indicate this condition to the operator.
