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 1):
A method for controlling a liquid ejection apparatus including an ejection port that ejects a liquid, a pressure chamber communicating with the ejection port and having therein an energy generating element to generate energy for ejecting the liquid, first and second flow paths communicating with the pressure chamber to supply the liquid to the pressure chamber and to collect the liquid from the pressure chamber, a negative pressure generating section configured to generate a negative pressure, a negative pressure control section using the negative pressure generated by the negative pressure generating section to adjust a pressure of the liquid flowing through one of the first and second flow paths that is connected, and a supply control section configured to control the supply of the liquid to the pressure chamber and the stop of the supply, characterized by:\n stopping a flow of the liquid by stopping the supply of the liquid by the supply control section and then stopping the negative pressure generating section.
