Abstract
A fluid ejection device includes a fluid storing unit and a fluid outlet. A fluid pressing unit presses the fluid storing unit and causes fluid to flow from the fluid outlet. A connection pipe has an end that is connected to the fluid outlet. A fluid ejection unit ejects the fluid, which is received from a fluid intake port to which the other end of the connection pipe is connected, in a pulse-like manner according to a drive signal generated by a fluid-ejecting control unit. An ejecting-instruction input unit receives a fluid ejecting instruction. If the pressure in the fluid storing unit is equal to or higher than an upper limit value in a range determined with reference to a target pressure value, the drive signal is not generated. When the pressure in the fluid storing unit is lower than the upper limit value, the drive signal is generated.
