Abstract

Disclosed is a dry ink clearing device that can be adapted to a toner/developer sensor imbedded in the material's flow path. Historically, dry-ink sensors of the piezoelectric variety comprise a high frequency, low amplitude vibrating surface that is easily dampened by the presence of a powder. A submerged sensor of this type is vulnerable to toner bridging across the sensing member causing a false dampened state or a failure to detect an exposed condition. Mechanical agitators added to the dispenser system for clearing the sensor are only marginally effective because of working tolerances that inhibit the delicate proximity required to clear the sensor. Moreover, the sensor may not
