摘要： A liquid discharge apparatus includes a liquid discharge head configured to discharge a liquid onto a medium, a carriage mounting the liquid discharge head configured to move the liquid discharge head in a main scanning direction, a dummy-discharge receptacle to receive a dummy-discharge liquid discharged from the liquid discharge head in a dummy-discharge operation, a light irradiator to irradiate the dummy-discharge liquid in the dummy-discharge receptacle with a light, and circuitry. The circuitry sets a plurality of dummy-discharge areas virtually dividing an interior of the dummy-discharge receptacle, moves the carriage in the main scanning direction to a first dummy-discharge area among the plurality of dummy-discharge areas, drives the liquid discharge head to discharge the dummy-discharge liquid onto the first dummy-discharge area in the dummy-discharge receptacle, and irradiates the dummy-discharge liquid in the first dummy-discharge area in the dummy-discharge receptacle with the light.
