Abstract
A fluid ejection device includes a fluid ejection unit that ejects a fluid, an ejection control unit that controls the ejection of the fluid from the fluid ejection unit, a fluid container that accommodates the fluid to be supplied to the fluid ejection unit, and a pressure adjustment unit that adjusts an inner pressure of the fluid container in such a manner that the inner pressure of the fluid container gets closer to a target pressure than a first threshold value for the inner pressure of the fluid container. When the inner pressure of the fluid container is closer to the target pressure than a second threshold value that is separated further from the target pressure than the first threshold value, the ejection control unit receives a demand for the ejection of the fluid.
