Abstract

Substrates used in the fabrication of photoreceptors can be surface treated with a honing process to provide a more nonreflective surface. Honing involves spraying the substrate surface with a honing slurry containing abrasive media in a liquid. The honed surface can minimize or eliminate the optical interference effect that can occur in a photoreceptor which can degrade the print quality. A typical honing process involves pumping the honing slurry through a spray gun at moderate pressure. However, the action of the pump causes the honing slurry to arrive at the gun in pulses which can cause the honed surface to have an undesirably non-uniform surface. Additionally, the spray gun can fail to operate due to clogging.

Substrates used in the fabrication of photoreceptors can be surface treated with a honing process to provide a more nonreflective surface. Honing involves spraying the substrate surface with a honing slurry containing abrasive media in a liquid. The honed surface can minimize or eliminate the optical interference effect that can occur in a photoreceptor which can degrade the print quality. A typical honing process involves pumping the honing slurry through a spray gun at moderate pressure. However, the action of the pump causes the honing slurry to arrive at the gun in pulses which can cause the honed surface to have an undesirably non-uniform surface. Additionally, the spray gun can fail to operate due to clogging.

The honing process is improved by removing the slurry pumps from the honing slurry delivery system which delivers honing slurry to the spray gun. The honing slurry is caused to flow through the spray gun via aspiration, ie., the flow of compressed air through the gun causes the honing slurry to be pulled through the gun with the compressed air. Thus, the present method eliminates the non-uniformities in the honed surface caused by pump pulsations.
