Abstract
A drop ejection system includes a drop ejection head and a reservoir. An air pump produces a partial vacuum above a fluid body in the reservoir to remove dissolved air or vapor in the fluid.
Claims55
A drop ejection system, comprising:
- a drop ejection head comprising a plurality of nozzles for ejecting a fluid;
- a first reservoir adapted to hold a fluid and have a space above the fluid;
- a first fluid path that connects a lower portion of the first reservoir with the drop ejection head;
- a second reservoir adapted to hold a fluid and have a space above the fluid;
- a second fluid path that connects a lower portion of the second reservoir with the first reservoir;
- and
- an air pump coupled to an upper portion of the second reservoir to produce a partial vacuum in the space above the fluid in the second reservoir.

A drop ejection system, comprising:
- a drop ejection head comprising a plurality of nozzles for ejecting a fluid;
- a reservoir adapted to hold a fluid in its lower portion;
- a first fluid path that can supply the fluid from the lower portion of the reservoir to the drop ejection head;
- a first fluid valve that can shut off the fluid connection from the lower portion of the reservoir to the drop ejection head;
- and
- an air pump to produce a partial vacuum in the upper portion of the reservoir.
3 more elements
A method of removing dissolved gas in a fluid ejection system, comprising:
- providing a fluid in a second reservoir that is in fluid communication with a first reservoir;
- producing a partial vacuum in a space above the fluid in the second reservoir;
- supplying the fluid in the second reservoir to the first reservoir, the first reservoir having a space above the fluid;
- and
- supplying the fluid in the first reservoir to a drop ejection head.
2 more elements
A method of removing dissolved gas in a fluid ejection system, comprising:
- providing a fluid in a reservoir;
- sealing fluid communications to the fluid in the reservoir;
- producing a partial vacuum in a space above the fluid in the reservoir;
- supplying the fluid in the reservoir to a drop ejection head having one or more nozzles for ejecting fluids;
- translating the fluid ejection head relative to a receiver without moving the reservoir;
