Liquid discharge apparatus

A liquid discharge apparatus comprising:

• a liquid discharge head including a nozzle capable of discharging a liquid;
• a circulation mechanism configured to circulate the liquid supplied to the liquid discharge head;
• a heating element configured to perform temperature adjustment of the liquid circulated by the circulation mechanism;
• a temperature sensor configured to detect a temperature of the liquid circulated by the circulation mechanism;
• and
• a cap capable of capping the nozzle that discharges the liquid in the liquid discharge head,
• wherein the circulation mechanism circulates the liquid based on a detection result of the temperature sensor in a state in which the nozzle is capped by the cap,
• when starting printing of an image, if a predetermined time has elapsed since the preceding circulation of the liquid, circulation of the liquid by the circulation mechanism is performed after temperature adjustment by the heating element is started, and
• when starting printing of an image, if the predetermined time has not elapsed since the preceding circulation of the liquid, temperature adjustment by the heating element is performed after circulation of the liquid by the circulation mechanism is started.

• the apparatus includes a nozzle capable of discharging black ink and a nozzle capable of discharging white ink, and
• when starting printing of an image,
• for the white ink, circulation of the liquid by the circulation mechanism is performed after temperature adjustment by the heating element is started, and
• for the black ink, temperature adjustment by the heating element is performed after circulation of the liquid by the circulation mechanism is started.
