ABSTRACT:
A liquid ejection apparatus has a liquid cartridge including a liquid container that has a flexible portion and stores liquid therein and a pressure chamber for applying pressure to the flexible portion of the liquid container; a liquid ejection head for ejecting liquid; a liquid flow path for guiding liquid from the liquid container to the liquid ejection head; a pressure pump for generating pressurized air; and an air flow path for guiding the pressurized air to the pressure chamber. The pressure pump includes an air chamber that communicates with the air flow path and a pressing member for pressing the air chamber so as to decrease the capacity of the air chamber. The capacity of the air chamber is decreased by the pressing member so as to increase the pressure in the air chamber to an upper limit value of a liquid supply pressure range where a prescribed liquid ejection characteristic is obtained, before a liquid ejecting operation is performed on an ejection target member. A continuous liquid ejecting operation is performed on an ejection target member having a maximum size for the liquid ejection apparatus in a state that the capacity of the air chamber is fixed.
