Abstract

A method of removing particulates from an ink ejection face of a printhead is provided. The method comprises the steps of: (a) flooding the face with ink from the printhead, thereby dispersing the particulates into the flooded ink; and (b) transferring the flooded ink, including the particulates, onto a transfer surface moving past the face. Damage to the face is avoided since the transfer surface does not contact the face.
