Abstract

A printing apparatus includes an ink ejecting head which ejects a UV ink, a sub-tank which reserves the UV ink, an ink circulation flow path which includes a circulation outgoing path in which the UV ink which is supplied to the ink ejecting head from the sub-tank flows and a circulation return path in which the UV ink which returns to sub-tank from the ink ejecting head flows, and a check valve which is provided in the circulation return path and is capable of opening and closing the circulation return path, in which the circulation return path is opened by the check valve when the UV ink flows in the circulation return path in a forward direction, and the circulation return path is closed by the check valve when the UV ink flows in the circulation return path in a reverse direction.
