Abstract: An inkjet printer maintenance system includes a manifold having an air removal passageway communicating with an ink reservoir, a valve in the manifold actuatable for opening and closing the air removal passageway for periodically drawing out air from the flow of ink in the ink reservoir and a valve actuator in the form of an electrically conductive wire sensitive to change in temperature. In response to application of electric current, and termination of application of electric current, the wire correspondingly contracts and extends in length causing the opening and permitting the closing of the air removal passageway by the valve.

Abstract: An adjustment assembly adjustably mounts opposite ends of elongated guide members on opposite side panels of a printhead carrier support frame of a printer to establish a desired mounting relationship between the guide members and opposite side panels and thereby establish a desired print gap between a sheet of print media passing through a print zone and a printhead supported on a carrier reciprocally moving on the guide members. In addition to the opposite side panels, the adjustment assembly includes a pair of adjustment plates each for placement in a facing relationship with an outside surface of one of the opposite side panels and a plurality of mounting elements associated with the adjustment plates and opposite side panels that enable aligning and mounting them at the opposite ends of the guide members in the desired mounting relationship that establishes the desired print gap.
