Abstract:
A fluid ejection device includes a fluid ejection unit that ejects a fluid and an ejection control unit that controls ejection of the fluid. A fluid container accommodates the fluid supplied to the fluid ejection unit. A pressure adjustment unit adjusts an inner pressure of the fluid container such that the inner pressure gets closer to a target pressure than a first threshold value. The ejection control unit has first and second ejection modes. In the first ejection mode, when the inner pressure is closer to the target pressure than a second threshold value separated from the target pressure farther than the first threshold value, the ejection control unit receives a demand for ejection of fluid. In the second ejection mode, even when the inner pressure is not closer to the target pressure than the second threshold value, the ejection control unit receives a demand for ejection of fluid.
