Abstract

See full text

A liquid ejection device includes: a nozzle through which a liquid is ejected; a liquid transporting pipe coupling to the nozzle; a pulsation generator configured to change a volume of a liquid chamber coupling to the liquid transporting pipe; a pump configured to send a liquid to the liquid transporting pipe; and a control unit configured to control driving of the pulsation generator and the pump. The control unit drives the pulsation generator and the pump such that Vf/Q is 0.3 or more, in which V [mm3] is a volume change amount of the liquid chamber, Q [mL/min] is a flow rate of a liquid to the liquid transporting pipe by the pump, and f [kHz] is a frequency at which the pulsation generator applies a pulsation to a liquid.
