Zusammenfassung:A priming device for a fluid ejection head and a method for priming a fluid ejection head. The priming device includes a Venturi tube having a motive fluid inlet, a suction inlet, a fluid outlet, and a motive fluid source configured to provide pressurized fluid to the fluid inlet of a Venturi tube and configured to provide a reduced pressure at the suction inlet of a Venturi tube. An ejection head sealing device is provided in fluid flow communication with an ejection head of a fluid cartridge and the suction inlet of the Venturi tube.
