Patent abstract
A liquid ejection apparatus includes a supply control section that controls the supply and stop of a liquid to pressure chambers communicating with ejection ports to eject the liquid, and a negative pressure generating section that generates a negative pressure. The liquid ejection apparatus also includes a negative pressure control unit using the negative pressure generated by the negative pressure generating section to adjust the pressure of the liquid flowing through a collection channel. To stop a flow of the liquid, the supply control section stops the supply of the liquid, and then the negative pressure generating section is stopped.
