Abstract: An apparatus for coating photoreceptor devices comprises a manifold forming a conduit, the conduit having a length with an input at one end. Multiple diptanks for applying photoreceptor coating solution to devices dipped therein are mounted on an upper portion of the manifold and distributed along the length. The conduit is arranged so that photoreceptor coating solution supplied to the input flows to the diptanks, thus forming a photoreceptor coating solution flow in each diptank. The conduit becomes increasingly narrower as the photoreceptor coating solution flows along the length successively from one diptank to the next diptank. As a result, the photoreceptor coating solution flow speed in each diptank is substantially the same.
