LIQUID DISCHARGE APPARATUS

A liquid discharge apparatus (1) includes a head (100) to discharge a liquid; a circulation passage (500) coupled to the head (100), through which a temperature-controlled liquid circulates; a radiator (511) including a fan (511a), to cool the temperature-controlled liquid; a head drive board (160)...

Summary:A liquid discharge apparatus (1) includes a head (100) to discharge a liquid; a circulation passage (500) coupled to the head (100), through which a temperature-controlled liquid circulates; a radiator (511) including a fan (511a), to cool the temperature-controlled liquid; a head drive board (160) mounted with a power amplification unit (161) to amplify a drive waveform applied to the head (100); an ambient temperature sensor (811) to detect an ambient temperature of the radiator (511); a liquid temperature sensor (812) to detect a temperature of the temperature-controlled liquid at an inlet of the radiator (511); and a controller (801). The controller (801) controls at least one of a rotation of the fan (511a) and a heating waveform applied to the head drive board (160), based on a target temperature of the temperature-controlled liquid, the ambient temperature of the radiator (511), and the temperature of the temperature-controlled liquid at the inlet of the radiator (511).
