Abstract
A printer has a print engine with an ink supply chamber connected to the print engine. The supply chamber has an exit aperture to which a suction device is connected. A gas permeable film associated with the aperture separates the chamber from the suction device. The suction device may be a resilient spring member that occasionally is composed during winter carriage reciprocation to maintain suction, or may be a vacuum pump. A porous may support the film.
