摘要： A liquid ejecting apparatus includes a liquid ejecting head having a first nozzle row, a first tank storing a first liquid, a first supply flow path, a first on-off valve provided in the first supply flow path and configured to open and close the first supply flow path, and a first pressurizing mechanism configured to pressurize the first tank. A pressure inside the first tank is set to a predetermined positive pressure by driving the first pressurizing mechanism in a closed state of the first on-off valve. Thereafter, a discharge process of discharging the first liquid from the first nozzle row is performed by bringing the first on-off valve into an open state. In the discharge process, the first on-off valve is switched from the open state to the closed state at a timing at which the first liquid is being continuously discharged from the first nozzle row.

摘要： A liquid ejecting head includes: a nozzle configured to eject a liquid; first to fourth pressure chambers; a communication flow path coupled to the nozzle and communicating between the nozzle and the first to fourth pressure chambers; first to fourth flow paths coupling the communication flow path and the first to fourth pressure chambers; first to fourth driving elements configured to change a pressure in the first to fourth pressure chambers; a first common liquid chamber communicating with the first pressure chamber and the second pressure chamber; and a second common liquid chamber communicating with the third pressure chamber and the fourth pressure chamber. The first flow path and the second flow path are arranged side by side in a first direction, the third flow path and the fourth flow path are arranged side by side in the first direction, and the first flow path and the second flow path, and the third flow path and the fourth flow path are arranged to be shifted in a second direction orthogonal to the first direction. The first flow path is shifted from each of the third flow path and the fourth flow path in the first direction, and the second flow path is shifted from each of the third flow path and the fourth flow path in the first direction.

摘要： A liquid ejecting head that has an ejection surface configured to ejecti a liquid includes a plurality of head chips that are long in a first direction. The plurality of head chips are arranged inside a virtual parallelogram including a first virtual side and a second virtual side that are in contact with at least one of the plurality of head chips and that extend in the first direction, and a third virtual side and a fourth virtual side that are in contact with at least one of the plurality of head chips and that extend in a second direction intersecting the first direction, and the ejection surface is not overlapped with an acute-angled portion of the virtual parallelogram when the ejection surface is viewed in a normal direction of the ejection surface.
