  • Publication number: 20230166503
    Abstract: A liquid ejecting apparatus includes an ejecting unit that ejects liquid when a drive signal is supplied to the ejecting unit, a drive signal output unit that outputs the drive signal, a cooling unit that cools the drive signal output unit, and a power supply unit that supplies power to the cooling unit. The liquid ejecting apparatus has a first mode in which the drive signal output unit outputs a first drive signal of a first frequency, and a second mode in which the drive signal output unit outputs a second drive signal of a second frequency lower than the first frequency. An amount of power supplied by the power supply unit to the cooling unit in the first mode is larger than an amount of power supplied by the power supply unit to the cooling unit in the second mode.
