Abstract
A fluid ejection device includes: a fluid chamber; a volume varying unit configured to vary the volume of the fluid chamber; a fluid supplying unit configured to supply fluid to the fluid chamber at a predetermined pressure; and an ejection command switching unit configured to switch a fluid ejection between a pulsed flow ejection which ejects the fluid in a pulsed manner by activating the volume varying unit and varying the volume of the fluid chamber and a continuous flow ejection which ejects the fluid with a fluid supply pressure from the fluid supplying unit higher than that in the case of the pulsed flow ejection in a state in which the volume varying unit is stopped.
