Abstract

Contamination is a major cause of manufacturing defects in active matrix creating high costs to production. The size of the toner particles range from .5 to 100 microns in diameter. These particles come from outside sources and are also generated in the web coating process. Moving cleaning webs electrostatically attract loose particles that can become embedded in the active matrix surface when coatings are applied over them. These toner particles are difficult to remove and cause unacceptable defects in the developed xerographic image. Commercial cleaning procedures are not effective in ensuring a cleaned web.

ACOUSTIC ASSIST ACTIVE MATRIX PHOTORECEPTOR WEB SURFACE CLEANER(Cont'd)

Contamination is a major cause of manufacturing defects in active matrix creating high costs to production. The size of the toner particles range from .5 to 100 microns in diameter. These particles come from outside sources and are also generated in the web coating process. Moving cleaning webs electrostatically attract loose particles that can become embedded in the active matrix surface when coatings are applied over them. These toner particles are difficult to remove and cause unacceptable defects in the developed xerographic image. Commercial cleaning procedures are not effective in ensuring a cleaned web.

The present invention, shown in Figure 1, proposes to improve both active matrix and benzimidazole perylene photoreceptor 50 fabrication yielded by acoustically dislodging the contaminants from the web 30 prior to a coating application (acoustic cleaning assist) as applied to image transfer processes. Models for determining vibration energy for dislodging particles as a function of size and density have been developed and can be exercised for any particle contaminant problem to determine...
