Abstract
A priming element for priming or maintaining the nozzles or orifices of an ink jet printhead in an ink jet printer. The priming element applies a vacuum or negative pressure generated by a suction device to the nozzles. The priming element includes a first wall and a second wall spaced from the first wall to define a passageway between the first wall and the second wall. One or more support members connect the first wall to the second wall and span the passageway to prevent the walls of the priming element from collapsing from the applied vacuum or negative pressure.
