Abstract:
A liquid ejection apparatus includes a supply control section  401  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  1004  that generates a negative pressure. The liquid ejection apparatus also includes a negative pressure control unit  230  using the negative pressure generated by the negative pressure generating section  1004  to adjust the pressure of the liquid flowing through a collection channel. To stop a flow of the liquid, the supply control section  401  stops the supply of the liquid, and then the negative pressure generating section  1004  is stopped.

Claim (Index 4):
The method for controlling a liquid ejection apparatus according to  claim 3 , wherein\n the liquid ejection apparatus further includes a storage container configured to store the liquid, the storage container having a water head lower than a pressure applied by the negative pressure control section, and a first pressure control valve connected in parallel with the circulation pump, the circulation pump and the pressure control valve communicate with the storage container, and the first pressure control valve is opened after the negative pressure generating section is stopped.
