Abstract: The disclosed print head has a two-chamber main reservoir that decouples wasted ink and purge volume in print heads. The two-chamber structure of the print head allows for varying flow of ink through the print head's internal manifolds without varying the wasted ink out of the jet stack. The main reservoir of the print head includes a recirculation chamber and an incoming ink chamber. A vacuum is applied to a vent in the recirculation chamber and a pressure can also be applied to a vent in the incoming ink chamber to cause bubbles in the jet stack to move into the recirculation chamber and be removed through the recirculation chamber vent.

Abstract: A liquid ink delivery system for use in an inkjet printer includes a plurality of conduits. Each conduit is configured to deliver liquid ink from reservoirs to printheads. The conduits are essentially comprised of a first material which is non-reactive with the liquid ink and which does not facilitate cooling or congealing of the liquid ink as the ink passes through the conduits. The conduits also include coatings applied to the first material that have further properties suited to delivery of ink and additives within the liquid ink. In one embodiment, an oxygen impermeable coating is applied to the conduit to reduce the risk of the ink or an additive within the ink oxidizes during transport through the conduit.

Abstract: A plastic grille is attached to vehicle fenders by fasteners having a first connector section particularly shaped to snappingly engage a hole in the grille, and having an oppositely-facing second connector section particularly shaped to snappingly engage a hole in the fenders. The first and second connector sections are shaped for optimal low insertion force, yet high retention force. The first and second connectors have flexible arms that are oriented 90 degrees apart, permitting the connectors to slip in perpendicular directions in their respective receiving holes, thus providing improved tolerance and adjustability during installation. A method of assembly includes pre-attaching the fastener to the plastic component, and then attaching them as a unit to the metal component.
