Abstract
A liquid jet recording apparatus includes a liquid container that contains liquid, a jetting portion disposed at a lower level than the surface of the liquid contained in the liquid container for jetting the liquid, and a conduit for communicating the jetting portion with the liquid container. An on-off valve opens or closes the conduit to permit or block the flow of the liquid in the conduit. A liquid storing portion damps pressure fluctuations of the liquid which flows in the conduit and is disposed in the conduit between the on-off valve and the jetting portion. A pressure sensor measures the pressure of the liquid in the conduit, and a control portion controls the on-off valve to be opened or closed based on a pressure value measured by the pressure sensor.
