A power supply section includes a switching regulator. A plurality of linear regulators is provided for respective ones of a plurality of driving sections. The linear regulators step down a source voltage to respective driving voltages of the driving sections and supply the respective driving sections with the driving voltages. A head-temperature sensor measures temperature of a liquid ejecting head. A controller determines the source voltage and the driving voltages based on the temperature, and controls the power supply section, the linear regulators, and the driving sections to stop at least one of outputting of the source voltage by the power supply section, supplying of the driving voltages by the linear regulators, and driving of the driving sections, when a voltage difference is larger than or equal to an acceptable value. The voltage difference is a difference between the source voltage and a minimum voltage of the driving voltages. |
