Abstract
An imaging system and method incorporate an apparatus and method for cleaning developer liquid from an imaging substrate such as a photoreceptor. The system and method operate to move the imaging substrate in a first direction, form a latent electrostatic image on an imaging region of the imaging substrate, engage a development device in proximity with the imaging substrate, load a squeegee roller against the imaging substrate, the squeegee roller being driven by the imaging substrate in the first direction, apply developer liquid from the development device to the imaging region, thereby developing the latent electrostatic image, terminate application of developer liquid from the development device upon movement of a nonimaging region of the imaging substrate past the development device, wherein the disengagement of the development device leaves on the imaging substrate a second excess volume of the developer liquid, drive the squeegee roller in a second direction upon movement of the nonimaging region past the squeegee roller, the squeegee roller substantially removing the second excess volume of developer liquid, and transfer the developer liquid remaining on the imaging region to an imaging substrate, thereby forming a representation of an image.
