摘要： A fluid ejection device includes: a fluid chamber whose capacity is variable; an inlet flow path and an outlet flow path communicating with the fluid chamber; a capacity changing unit which changes the capacity of the fluid chamber; a fluid supplying unit which supplies fluid to the inlet flow path; a fluid ejection opening disposed at an end of the outlet flow path opposite to an end communicating with the fluid chamber; a vibrating unit which vibrates a component in the vicinity of the fluid ejection opening; a vibration detecting unit which detects the level of vibration of the component in the vicinity of the fluid ejection opening; and an operation control unit which controls operation of the capacity changing unit based on the level of the vibration detected by the vibration detecting unit.
