Abstract: A liquid jet unit includes a circulation path through which liquid is circulated, and a liquid jet head having an inflow port and an outflow port between which is disposed a flow path forming a part of the circulation path, and a nozzle communicating with the flow path and configured to eject liquid from the liquid jet head. A liquid pump is inserted into the circulation path for circulating liquid in the circulation path. A supply path is connected to the circulation path for supplying liquid to the circulation path. A pressure sensor detects the pressure of liquid in the circulation path and generates corresponding pressure information. The liquid pump is configured to change an amount of liquid to be fed on the basis of the pressure information generated to maintain liquid in the nozzle at a predetermined pressure and draw liquid into the circulation path from the supply path.
