Apparatus for applying a prewetting solution to an image-bearing surface of a photoelectrostatic master sheet, which apparatus includes a scrubber roll rotatably disposed in pressure contact with the bearing surface of a guide plate which is submersed in a prewetting solution contained in a reservoir, and two spaced sets of rotatably mounted rolls arranged to advance a photoelectrostatic master sheet from an input position where the sheet is submersed, through the nip formed by the scrubber roll against the bearing surface where the image-bearing surface of the master sheet is lightly scrubbed to remove loose toner particles and to prepare it for reproduction, and to an exit position where excess prewetting solution is removed from the surface of the master sheet.
