Abstract

Where an ultrasonic probe is used to remove leftover developing material from the surf ace of a xerographic photoconductor, the high-f requency oscillation of the probe sets up a nodal pattern which results in deposits of toner being built up at high/low pressure points. This results in poor cleaning of the photoconductor surface and can occur irrespective of whether or not the probe is air or fluid coupled to the photoconductor surface.

Where an ultrasonic probe is used to remove leftover developing material from the surf ace of a xerographic photoconductor, the high-f requency oscillation of the probe sets up a nodal pattern which results in deposits of toner being built up at high/low pressure points. This results in poor cleaning of the photoconductor surface and can occur irrespective of whether or not the probe is air or fluid coupled to the photoconductor surface.

It is proposed that the nodal pattern produced at high/low pressure points be altered and eliminated by changing the contour of the probe surface. This can be effected by machining small changes in the probe surface to produce a series of high and low points on the probe surface. The resulting variation in the probe surface displaces the high and low pressure points to reduce or eliminate any tendency for toner to build up at these points.
