Abstract
A liquid ejection apparatus includes a heater controller and a purge controller. The heater controller controls a heater to heat liquid in at least a part of a liquid path of a head when an ambient temperature of the head is lower than a first predetermined temperature. The purge controller controls a pressurizer so that: the pressurizer is continuously driven until a predetermined amount of liquid is ejected from ejection openings, when the ambient temperature is not lower than the first predetermined temperature; and the pressurizer is intermittently driven plural times until the predetermined amount of liquid is ejected from the ejection openings, when the ambient temperature is lower than the first predetermined temperature, an amount of liquid ejected from the ejection openings in response to a single driving action of the pressurizer being not larger than an amount of liquid heated by the heater.
