摘要： A droplet ejection device includes a liquid ejection head, a supply flow path, a supply pump, and a supply flow path pressurizer. The supply flow path supplies the liquid to the head and for which a first depressurization threshold is specified in advance. The supply pump sucks the liquid, pressurizes the sucked liquid and supplies the sucked liquid to the head via the supply flow path, and keeps a pressure of liquid in the supply flow path near to a predetermined supply flow path target pressure. The supply flow path pressurizer pressurizes the pressure of liquid in the supply flow path if the pressure of liquid in the supply flow path falls to less than or equal to the first depressurization threshold.

摘要： A liquid droplet ejecting apparatus includes: a supply-use tank that is sectioned by an elastic film into a liquid chamber and a gas chamber; a supply-use flow path that interconnects the supply-use tank and a recording head; and a pump that pumps the liquid stored in the liquid chamber to the recording head via the supply-use flow path by supplying the liquid from an external tank to the liquid chamber of the supply-use tank. The flow path is controlled to supply the liquid to the liquid chamber in a state where the supply-use flow path is closed, cause the elastic film to press against an inner wall of the gas chamber, thereafter open the supply-use flow path, release the elastic film from the pressing state, and supply, with the pump, the liquid from the external tank to the recording head via the supply-use tank and the supply-use flow path.
