Abstract
A liquid ejection apparatus includes: a gas chamber surrounding a piezoelectric element in an inkjet head; and a dry gas supply device configured to start supply of dry gas to the gas chamber before supply of electric power to the inkjet head is started, to continue the supply of the dry gas while the supply of the electric power to the inkjet head is continued, and to halt the supply of the dry gas after the supply of the electric power to the inkjet head is halted. While the dry gas supply device halts the supply of the dry gas to the gas chamber, a dry gas supply flow channel opening and closing device is closed to disconnect the dry gas supply device and the gas chamber, and a gas return flow channel opening and closing device is closed to disconnect the gas chamber and the external air.
