A liquid ejection apparatus includes a liquid ejection head, actuator units with actuators, a power supply that output a main voltage, and linear regulators that reduce the main voltage to drive voltages to be supplied to the relevant actuator units. When a voltage difference between the main voltage and drive voltage is greater than an allowable value for any of the actuator units, the apparatus controls a linear regulator so that the drive voltage supplied to at least one actuator unit is adjusted to a high drive voltage. A small ejection driving waveform is created as the driving waveform to be output to the actuators in the actuator unit to which the high drive voltage is supplied. |
