A liquid ejecting apparatus includes: a liquid ejecting head configured to eject a liquid from a nozzle provided on a nozzle surface; a first storage portion that has an introduction portion into which the liquid accommodated in a liquid accommodating portion is introduced, the introduction portion being provided at an upper portion of the first storage portion; a second storage portion that communicates with the first storage portion via a communication passage and to which the liquid is supplied from the first storage portion due to a water head difference; a supply flow path for supplying the liquid from the second storage portion to the liquid ejecting head; a pressurizing portion that pressurizes an inside of the second storage portion; and a first valve configured to close the communication passage at the time of pressurization by the pressurizing portion.

Liquid ejecting apparatus and control method of liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head configured to eject a liquid, a liquid supply flow path configured to supply the liquid from a liquid container containing the liquid to the liquid ejecting head, a pressurizing portion pressurizing an inside of the liquid supply flow path, and an solenoid valve which is provided in the liquid supply flow path and which opens the liquid supply flow path during energization and closes the liquid supply flow path during de-energization, in which open and closed states of the solenoid valve are forcibly switched in accordance with a pressure change by the pressurizing portion.

Liquid ejecting apparatus

A flow path member includes a flow path forming member; an elastic film which forms a flow path in a state in which a peripheral edge portion is in close contact with the flow path forming member; and a cover member which surrounds an outer edge portion of the elastic film along with the flow path forming member.

Flow path member and liquid ejecting apparatus

A flow path member includes a first flow path-forming member made of a material capable of absorbing a laser light and a second flow path-forming member made of a material that has a lower absorbance with respect to the laser light than the first flow path-forming member and having in a portion of an inner surface that at least partially forms a flow path at least one welded portion that is welded to the first flow path-forming member. An outer surface side of the second flow path-forming member that is an opposite side to the inner surface is provided with at least one light blocking portion capable of blocking the laser light and at least one transmitting portion that is capable of transmitting the laser light and that is positioned on an opposite side to the at least one welded portion and the at least one light blocking portion and the at least one transmitting portion are in contact on at least one boundary with each other. At least one external edge of the at least one welded portion is at a position that is shifted by a shift from the at least one boundary to a side toward which the laser light incident on the at least one boundary at an incident angle less than 90 degrees travels.
