Abstract: A method comprising: (a) overflowing a vessel with a coating solution, wherein there is a zone of stagnant coating solution within the vessel; (b) directing at least one fluid jet at the zone of the stagnant coating solution, thereby causing at least a portion of the stagnant coating solution to overflow the vessel; and (c) dip coating a substrate with the coating solution in the vessel, subsequent to the feature (b).

Abstract: An apparatus for coating a photoreceptor substrate, such as a photoreceptor belt or a photoreceptor drum, consists of at least one photoreceptor coating fluid reservoir or diptank. The diptank defines an inlet at one end and a conduit with an orifice at the other end. The conduit includes at least one porous element such as a grid, screen or mesh arranged for suspending a plurality of layers of non-contaminating rounded objects, such as stainless steel or glass beads, in the bottom of the conduit. Photoreceptor coating solution supplied to the inlet is thereby forced to flow through the plurality of layers of beads prior to coating a photoreceptor substrate that is inserted through the orifice. As a result, the uniformity of the coating solution is improved as it coats the photoreceptor substrate, thereby reducing coating defects in the finished photoreceptor belt or drum.
