Abstract
A method of removing foreign particulates from an ink ejection face of a pagewidth printhead mounted on a substrate. The substrate has a film guide positioned adjacent the printhead. The method comprises the steps of: (a) flooding the face with ink and dispersing the particulates into the flooded ink; (b) positioning a polymer film in a transfer zone so as to define a cavity defined by the ink ejection face, the film guide and the polymer film; and (c) guiding the polymer film through the transfer zone. The movement of the film in the transfer zone transfers the flooded ink onto the polymer film.
