Abstract

Toner adhering to the face and surrounding area of the low toner sensor in a copier/printer machine can lead to a situation in which the toner sensor fails to recognize when the machine toner dispenser is nearly empty. The machine is then unable to signal to the operator that it is time to add more toner, and as a result, copy density and quality falls off drastically. This usually results in an unscheduled maintenance call.

Referring to the drawing figures, it is proposed here that an inexpensive and easily installed anti-bridging device 4, which is designed to prevent toner from adhering to or bridging onto the face of the low toner sensor 5 and the immediate area surrounding the sensor be provided. The proposed anti-bridging device 4, which requires only minimal modification to typical copier/printer machines, is grounded on the observation that toner adhering to the face of the toner sensor 5 by itself is usually not sufficient to produce a sensor failure, but rather the accumulation of toner in the area surrounding the sensor provides a surface area on which added amounts of toner can accumulate and surround the sensor 5 and occlude the sensor face.

Anti-bridging device 4 comprises a piece of sma...
