ABSTRACT:
The liquid ejection apparatus includes: a liquid ejection device which ejects liquid; a liquid supply device which supplies the liquid to the liquid ejection device; a saturated dissolved gas amount determination device which determines a saturated dissolved gas amount of the liquid in the liquid ejection device; a dissolved gas amount determination device which determines a dissolved gas amount of the liquid in the liquid ejection device; a liquid restoration device which carries out a liquid restoration processing to reduce the dissolved gas amount of the liquid inside the liquid ejection device; and a liquid restoration control device which controls whether or not the liquid restoration device carries out the liquid restoration processing, according to a differential between the saturated dissolved gas amount determined by the saturated dissolved gas amount determination device and the dissolved gas amount determined by the dissolved gas amount determination device.
