ABSTRACT:
There is disclosed a photoreceptor material reclaim method comprising: (a) centrifuging a first photoreceptor coating solution comprised of a liquid, a photoreceptor material, and impurities, resulting in a residue composition comprised of a lower density material including a portion of the photoreceptor material and a higher density material including a portion of the impurities and a supernatant composition; (b) drying the residue composition to remove a portion of the liquid in the residue composition; (c) grinding the dried residue composition; (d) separating the lower density material from the higher density material of the dried, ground residue composition; (e) forming a second photoreceptor coating solution comprised of the lower density material obtained by (d); and (f) depositing the second photoreceptor coating solution comprised of the lower density material on a substrate.
