Abstract
A sequence that includes first processing of generating a positive flow in a first direction in a liquid in a first flow passage including at least a part of a circulation flow passage through which the liquid is supplied from a liquid tank to the liquid jetting head and the liquid is collected from the liquid jetting head to the liquid tank and second processing of generating a negative flow in an opposite direction to the first direction in the liquid in the first flow passage, is executed. In the first flow passage, a filter that removes a foreign substance in the liquid is disposed between the liquid tank and the liquid jetting head in the positive flow. A flow rate of the liquid of the positive flow is higher than a flow rate of the liquid of the negative flow. The negative flow has a steady flow state.
