Abstract
A squeegee apparatus and method for removing excess developer liquid from an imaging substrate in a liquid electrographic imaging system make use of a squeegee roller having a core with a crowned profile. With determination of a proper loading force, the squeegee apparatus and method achieve substantially uniform loading force along the length of the squeegee roller, and thus along the width of a nip formed along an the imaging region of the imaging substrate. As a result, the squeegee apparatus and method provide substantially uniform removal of developer liquid from the imaging substrate, enhancing quality of an ultimate printed image.
