Liquid ejecting apparatus and control method thereof

摘要

A liquid ejecting apparatus includes a liquid ejecting head which includes a manifold; a first flow path and a second flow path which are connected to the manifold; a switching unit which switches a communication state between a liquid storage unit and the respective first and second flow paths; a pressure regulating unit which includes a valve which is open due to negative pressure on the manifold side of the first flow path; and a control unit which controls the switching unit, in which the control unit is capable of performing switching between a first mode in which liquid is supplied to the manifold through the valve and a second mode in which liquid is supplied to the manifold without going through the valve.

1. A liquid ejecting apparatus comprising:
a liquid ejecting head which communicates with a nozzle opening which ejects liquid, and includes individual flow paths which are arranged in a line along a first direction, and a manifold which communicates with a plurality of the individual flow paths; a first flow path which is connected to one end side of the first direction of the manifold; a second flow path which is connected to the other end side of the first direction of the manifold; a switching unit which switches a communication state between a liquid storage unit in which liquid is stored and the respective first and second flow paths; a pressure regulating unit in fluid communication with the first flow path, which is provided between the switching unit of the first and second flow paths and the liquid ejecting head, and includes a valve which is open due to negative pressure on the manifold side of the first flow path; a pressure-feeding unit which sends liquid in a pressurizing manner toward the switching unit from the liquid storage unit; and a control unit which controls the switching unit, wherein the control unit is capable of performing switching between a first mode in which liquid is supplied to the manifold through the valve by causing the liquid storage unit and the first flow path to communicate with the switching unit and a second mode in which liquid is supplied to the manifold without going through the valve by causing the liquid storage unit and the second flow path to communicate with the switching unit.
