    摘要: A system for delivering at least two distinct pressures to a print head of an ink jet printer includes a pump, a passage in communication with the pump and the print head, and a valve. The pump is for delivering positive pressure to the print head of the ink jet printer. The passage includes an opening, and the valve selectively opens and closes the opening.

    摘要: A method of manufacturing an ink stick for use in a phase change ink jet imaging device comprises heating phase change ink material to an extrusion temperature at which the phase change ink material is in a malleable state. The ink material is then extruded through an extrusion orifice to form an extruded rail of ink. The extruded rail of ink is then roll formed to partially form a portion of a shape transverse to the extrusion direction as the rail of ink moves in the extrusion direction. A swaging process is then carried out to further form and divide the extruded rail of ink into ink sticks.
