Abstract (en)
There is provided a liquid discharge apparatus including: a liquid chamber that communicates with a nozzle; a liquid chamber driving unit that changes a volume of the liquid chamber so as to discharge the liquid from the nozzle; a flow channel which is connected to the liquid chamber; and a valve that changes a volume of the flow channel so as to control flow of the liquid. At least one of first control of increasing the volume of the liquid chamber in association with a decrease in volume of the flow channel by the valve, such that a change amount of the volume of the liquid chamber is equal to or larger than a volume of the liquid flowing from the flow channel into the liquid chamber due to the decrease in volume of the flow channel, and second control of decreasing the volume of the liquid chamber in association with an increase in volume of the flow channel by the valve, such that a change amount of the volume of the liquid chamber is equal to or larger than a volume of the liquid flowing from the liquid chamber out to the flow channel due to the increase in volume of the flow channel, is executed.
