Abstract:
A liquid circulation device comprises a liquid chamber connected with a liquid discharge section that discharges liquid and able to hold the liquid; a circulation section configured to circulate the liquid in a flow path containing the liquid chamber and the liquid discharge section; a liquid replenishment section configured to replenish the liquid to the liquid chamber; a gas control section configured to be able to pressurize or decompress the liquid chamber; and a control section configured to replenish the liquid through the liquid replenishment section in a case in which pressure of the liquid discharge section is in a predetermined reference range and lower than a predetermined threshold value, pressurize the liquid discharge section by pressurizing the liquid chamber through the gas control section in a case in which the pressure is lower than the reference range.
