Abstract:
A fluid ejection device includes: a pulse generation unit that changes the volume of a fluid chamber using a volume changing section to eject pulsating flow; a fluid supply unit including a pump chamber and a pump chamber volume changing section that changes the volume of the pump chamber to supply the fluid to the pulse generation unit; a drive control unit that inputs a pulsating flow drive signal for driving the pump chamber volume changing section and inputs a fluid supply drive signal for driving the fluid supply unit; and an operation command input unit that inputs an operation command to the drive control unit, wherein the fluid supply drive signal and the pulsating flow drive signal are input in conjunction with the input of the operation command.
