Abstract

There is provided a liquid discharge apparatus. A print head includes a nozzle that discharges a liquid. A recovery unit includes a cap that caps the nozzle and a pump that suctions a liquid from the nozzle via the cap, and discharges to a waste liquid tank that accommodates a waste liquid of suctioned liquid. A control unit causes the recovery unit to execute at least one of a first recovery operation, in which the suction pump is driven at a first driving amount, or a second recovery operation, in which the pump is driven at a second driving amount smaller than the first driving amount, based on an amount of waste liquid discharged to the waste liquid tank.
