Abstract

Disclosed is a method and apparatus for indicating paper jams, misfeeds, and the like paper path malfunctions, in electrostatographic printing and copying machines, and related machinery which employs cut sheet or continuous roll feed papers. The apparatus can be, for example, a visual or audio indicating sensor, such as a light emitting diode or liquid crystal display, that is strategically placed along a paper path. The indicating sensor shows an operator the actual location of a jammed sheet(@ by, for example, flashing or sounding to quickly draw the operator's attention to the malfunction area, and optionally providing simple visual or audio instructions for clearing the jam. The method and apparatus enables the operator to quickly troubleshoot and remedy most common paper handling problems. Other indicating means are known, for example, flashing lights on user interface panels. However, these tend to be less specific than indicators located at the actual site of the malfunction, and they require that the operator mentally map the user interface indication of the malfunction to the machine components concealed within the housing, which can be problematic for the uninitiated or inexperienced operator and occasional users. The proposed method and apparatus improves and simplifies machine operability, decreases jam clearance time, and reduces manufacturing costs by foregoing the expenses associated with the circuitry for an integrated user interface.
