Liquid ejection apparatus

A liquid ejection apparatus comprising:

• a head which has a plurality of ejection openings from which liquid is ejected and a liquid path which is connected to the ejection openings and formed inside the head;
• a pressurizer which pressurizes liquid in the liquid path of the head;
• a temperature sensor which detects an ambient temperature of the head;
• a heater which heats liquid in at least a part of the liquid path;
• a heater controller which controls the heater so that the liquid is heated by the heater when the ambient temperature detected by the temperature sensor is lower than a first predetermined temperature;
• and
• a purge controller which controls the pressurizer so that (i) the pressurizer is continuously driven until a predetermined amount of liquid is ejected from the ejection openings, when the ambient temperature detected by the temperature sensor is not lower than the first predetermined temperature and (ii) the pressurizer is intermittently driven a plurality of times until the predetermined amount of liquid is ejected from the ejection openings, when the ambient temperature detected by the temperature sensor 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.
