Abstract

It is well known in reproduction apparatus to provide electrical sheet sensors spaced at various positions along the machine's paper path, wired to the machine controller, to actuate a Graphical User Interface (GUI) display as to jammed sheets locations and/or display lights within the machine at the positions requiring jam clearances. However, such electrical (usually electro-optical) sensors can have paper lint contamination problems and both they and display lights are relatively expensive and require installation of a relatively expensive wiring harness to and from all the possible sheet jam locations along a paper path.
