Abstract
A liquid circulation device includes a liquid chamber that stores a liquid that is to be supplied to a liquid discharge head. A pipeline through which the liquid can be circulated between the liquid chamber and the liquid discharge head is provided. A heater heats the liquid circulating in the pipeline. A first temperature sensor measures the temperature of the heater, and a second temperature sensor measures the temperature of the liquid in the pipeline. A controller controls the heating of the heater based on the liquid temperature measured by the second temperature sensor. The controller also monitors a change in the measured temperature of the heater over time and turns off the heating of the heater when the monitored change satisfies a predetermined stop condition.
