Abstract
A fluid ejection device includes: a fluid ejection unit that ejects a fluid in a pulsed manner; a fluid accommodation portion that accommodates the fluid at a predetermined pressure or higher; a fluid supply unit that supplies the fluid accommodated in the fluid accommodation portion to the fluid ejection unit; a connection channel that connects the fluid ejection unit and the fluid accommodation portion, and acts as a channel through which the fluid flows; an opening and closing unit that opens and closes the connection channel; and a control unit that sends an open signal for opening the connection channel to the opening and closing unit, and sends an ejection signal for ejecting the fluid to the fluid ejection unit. The control unit sends the ejection signal after a predetermined amount of time has elapsed from the sending of the open signal.
