More Information
Summary:In the present invention, an air bubble residing in a filter chamber is purged at a high speed without inducing liquid ejection deficiency at a liquid ejection head. A filter chamber is divided into a first filter chamber and a second filter chamber via a filter. A pump circulates ink through an ink tube and a bypass path between an ink tank and the first filter chamber. A valve capable of regulating a flow of the ink is provided at the ink tube that allows the second filter chamber and a print head to communicate with each other.
