Abstract:
A liquid ejection apparatus including: a liquid ejection head including an inside channel; a supply channel; a return channel; a supply device; an adjusting device; and a controller, wherein the controller starts a liquid circulation control for circulating liquid through the supply channel, the inside channel, and the return channel in order by controlling: the adjusting device such that a channel resistance value of the return channel is less than a predetermined maximum value; and the supply device to supply the liquid into the inside channel, wherein, when the liquid is circulated, the controller starts a liquid discharge control for discharging the liquid by increasing the channel resistance value, wherein, when the liquid is discharged, the controller starts a liquid-discharge stopping control for stopping the discharge by decreasing the channel resistance value, and wherein the controller controls the supply device such that a liquid amount supplied to the inside channel per unit time when the discharge is stopped is less than that in the liquid circulation control.
