摘要:
The liquid ejecting head includes a first individual flow path and a second individual flow path for supplying liquid to a pressure chamber, a first common flow path for supplying liquid to the first individual flow path, and a second common flow path for supplying liquid to the second individual flow path. A first circulation for causing liquid to flow in the order of the first individual flow path, the pressure chamber, and the second individual flow path and a second circulation for causing liquid to flow in the reverse order of the first circulation are switched. A flow path resistance of the first common flow path is designed to be less than a flow path resistance of the second common flow path and a flow path resistance of the first individual flow path is designed to be less than a flow path resistance of the second individual flow path.
