[Object] To provide a liquid discharge apparatus, a liquid discharge control method, and a filling method including a pump using a tube, which realize high-accuracy liquid discharge. [Solving Means] A liquid discharge apparatus includes a liquid transfer pump, a first flow channel, a second flow channel, and a flow channel switching unit. The liquid transfer pump includes a flexible tube that allows a liquid to circulate therethrough, the liquid being supplied from a liquid storage unit that stores the liquid, a pressing unit that presses the flexible tube from an outer circumferential surface side and feeds the liquid from one end to another end of the flexible tube, and a drive unit that rotationally drives the pressing unit. A first flow channel and a second flow channel that are different from each other are flow channels to which a liquid transferred from the liquid transfer pump flows out. The flow channel switching unit is controlled to use, as the first flow channel, a flow channel to which a liquid for discharge that is transferred from the liquid transfer pump flows out and use, as the second flow channel, a flow channel to which a liquid transferred from the liquid transfer pump flows out until the drive unit moves to a position after the liquid for discharge is transferred, the position being a position where the drive unit is located when the liquid for discharge starts to flow out.
A liquid discharge apparatus, comprising:
A liquid discharge control method, comprising
A filling method, comprising
