Abstract:
A liquid circulation apparatus includes: a plurality of liquid ejection elements each of which includes a nozzle, a pressure chamber which is connected to the nozzle and accommodates liquid, and a piezoelectric element which displaces a wall of the pressure chamber to eject the liquid in the pressure chamber through the nozzle; a plurality of individual supply channels which are respectively connected to the liquid ejection elements; a common supply channel which is connected to the individual supply channels, the liquid being supplied from the common supply channel to the liquid ejection elements through the individual supply channels; a plurality of individual circulation channels which are respectively connected to the liquid ejection elements; a common circulation channel which is connected to the individual circulation channels, the liquid being circulated from the liquid ejection elements to the common circulation channel through the individual circulation channels; and a control device which controls a circulation volume of the liquid circulated from the liquid ejection elements to the common circulation channel, by adjusting a supply volume of the liquid supplied from the common supply channel to the liquid ejection elements in accordance with an ejection volume of the liquid ejected from the liquid ejection elements.
