Abstract
A jam detector in an inserting station of an inserter comprises horizontal and vertical photosensors and therewith associated retroreflective targets; the horizontal sensors have a light beam directed across and above an envelope positioned in the inserting station, and the vertical sensors have a pair of vertical light beams directed toward opening fingers while the fingers are positioned in the inserting station for holding envelopes open. The jam detector detects jam malfunctions during the inserting cycle by sensing interruption of the horizontal beam and uninterrupted retroreflection of the vertical beams.
