Abstract:
A fluid ejection device includes a fluid container having a fluid accommodation portion that has formed therein a fluid outlet and accommodates a fluid. A fluid pressing unit presses the fluid accommodation portion to cause the fluid to flow out of the fluid outlet. Connection piping has an end that is connected to the fluid outlet. A fluid ejection unit has a fluid intake port connected to the other end of the connection piping, and ejects in a pulsed manner the fluid received from the fluid intake port. A pressure detection unit detects pressure of the fluid accommodation portion when the fluid pressing unit presses the fluid accommodation portion, and outputs a level of a detection signal corresponding to the pressure. A press control unit stops the fluid pressing unit from pressing the fluid accommodation portion when the pressure indicated by the detection signal is a predetermined value or higher.
