Liquid jet head, liquid jet recorder and method for filling liquid jet head with liquid

A method of filling a liquid jet head with liquid, the liquid jet head including a jetting body having a jetting hole column formed of a plurality of jetting holes, a plurality of pressure generating chambers which are paired with and communicate with the plurality of jetting holes, respectively, a liquid supply system for supplying a first liquid to the plurality of pressure generating chambers and the plurality of jetting holes, and an actuator disposed adjacent to the plurality of pressure generating chambers, the actuator being driven to pressurize the plurality of pressure generating chambers, thereby causing the first liquid to be jetted from liquid nozzles of the plurality of jetting holes,

• the liquid jet head comprising:
• a wall portion provided so as to surround a periphery of the jetting body and having an opening opposed to the plurality of jetting holes;
• an opening and closing mechanism for, in an open state, opening the opening to expose the plurality of jetting holes to outside and for, in a closed state, closing the opening to form closed space between the wall portion and the jetting body;
• a suction flow path having a suction port which is open below the jetting hole column of the jetting body for communicating with the closed space;
• a suction flow path having, on one end side thereof, a suction port which is open below the jetting hole column while another end side thereof being connected to a sucking portion for, by sucking an inside of the closed space with the sucking portion, causing the closed space to become a negative pressure chamber to supply the first liquid from a supply source of the first liquid;
• and
• an atmosphere release portion for communication between the closed space and the outside,
• the method of filling a liquid jet head with liquid comprising the steps of:
• in the closed state of the opening and closing mechanism, carrying out interruption by the atmosphere release portion and carrying out suction filling of the first liquid from the supply source into the plurality of pressure generating chambers and the plurality of jetting holes with the sucking portion via the suction flow path;
• and
• after the suction filling of the first liquid, in the closed state of the opening and closing mechanism, causing the atmosphere release portion to communicate, and sucking with the sucking portion via the suction flow path an excess of the first liquid which exists in the closed space.
