Abstract
A method of removing gas from a printhead is provided. A sealing material may be applied to orifices of a printhead from external the printhead to restrict passage of fluid through the orifices. Ink may be moved through a printhead conduit disposed in fluid communication with the orifices to create an inward suction adjacent the orifices so that the gas is displaced from adjacent the orifices.
