A process for treating an electrostatographic imaging member including providing a hollow cylindrical electrostatographic imaging member having an interior surface, a coated outer surface, a first end and a second end, the interior surface at at least the first end having a coating of adhesive material securing a first end flange to the first end, and propelling solid carbon dioxide pellets against the first end flange and coating of adhesive material with sufficient force to remove the first end flange and coating of adhesive material from the interior surface at at least the first end of the hollow cylindrical electrostatographic imaging member.

Hollow cylindrical imaging member treatment process with solid carbon dioxide pellets

There are disclosed apparatus and substrate coating methods comprising: (a) positioning a first coupler comprised of a tapered end portion in an opening of a reservoir apparatus to define a reservoir for a coating solution between the surfaces of the first coupler and the reservoir apparatus, wherein the tapered end portion of the first coupler extends below the opening; (b) engaging the bottom end of a vertically disposed, hollow substrate with a first end portion of a second coupler comprised of the first end portion and an opposed, tapered second end portion; (c) moving the top end of the substrate over a part of the tapered end portion of the first coupler to engage the substrate with the first coupler, and moving the first coupler and the substrate through the opening, whereby the coating solution is deposited on the outer surface of the substrate; (d) positioning the second coupler in the opening to define the reservoir, wherein the tapered second end portion of the second coupler extends below the opening; and (e) adding the coating solution to the reservoir at any suitable time.
