Abstract
A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected.
