Abstract
A priming device for a fluid cartridge, a fluid dispense device configured for priming the fluid cartridge, and a method for priming a fluid cartridge. The priming device includes an impact mechanism for a fluid cartridge, wherein the fluid cartridge is devoid of a backpressure device and has a fluid reservoir and an ejection head chip in fluid flow communication with the fluid reservoir.
Claims18
A priming device for a fluid cartridge comprising an impact mechanism configured to impact an external side of the fluid cartridge, wherein the fluid cartridge is devoid of a backpressure device and has a fluid reservoir and an ejection head chip in fluid flow communication with the fluid reservoir.
A fluid dispense device comprising:
- a fluid cartridge devoid of a backpressure device, wherein the fluid cartridge has a fluid reservoir and an ejection head chip in fluid flow communication with the fluid reservoir;
- a fluid cartridge translation mechanism for moving the fluid cartridge in a first direction across a substrate;
- and
- an impact head attached to a frame member of the fluid dispense device configured for priming the fluid cartridge, wherein the impact head is configured to impact an external side of the fluid cartridge.
A method for priming a fluid cartridge comprising:
- providing a fluid cartridge devoid of a backpressure device, wherein the fluid cartridge has a fluid reservoir and an ejection head chip in fluid flow communication with the fluid reservoir;
- and
- impacting an external side wall of the fluid cartridge with an impact mechanism.
A method for priming a fluid cartridge comprising:
- providing a fluid cartridge devoid of a backpressure device, wherein the fluid cartridge has a fluid reservoir and an ejection head chip in fluid flow communication with the fluid reservoir;
- and
- rapidly accelerating the fluid cartridge in a direction perpendicular to a plane defined by a nozzle plate of the ejection head chip.
