Claim 21:
22. A method of flowing a liquid in a line head assembly, the line head assembly including:
a line head including a first head, a second head and a third head arranged in a first direction, the second head being arranged between the first head and the third head in the first direction, positions of the first head and the third head being same in a second direction crossing the first direction, and the positions of the first head and the third head in the second direction being different from a position in the second direction of the second head; and
a tank located above the line head in an up-down direction crossing the first direction and the second direction,
wherein each of the first head, the second head and the third head includes:
a first intra-head channel including a first pressure chamber and a first nozzle;
a first supply port connected to one end of the first intra-head channel; and
a first discharge port connected to the other end of the first intra-head channel,

wherein the tank includes:
a first supply channel formed in the tank and connected to the first supply port of the first head, the first supply port of the second head and the first supply port of the third head; and
a first discharge channel formed in the tank and connected to the first discharge port of the first head, the first discharge port of the second head and the first discharge port of the third head, and

wherein the first supply channel includes a first main supply channel and first branched supply channels A, B and C,
wherein the first discharge channel includes a first main discharge channel and first branched discharge channels A, B and C;
wherein the first main supply channel is connected to one end of each of the first branched supply channels A, B and C,
wherein the other end of the first branched supply channel A is connected to the first supply port of the first head, the other end of the first branched supply channel B is connected to the first supply port of the second head, and the other end of the first branched supply channel C is connected to the first supply port of the third head;, the first main discharge channel is connected to one end of each of the first branched discharge channels A, B and C, and
wherein the other end of the first branched discharge channel A is connected to the first discharge port of the first head, the other end of the first branched discharge channel B is connected to the first discharge port of the second head, and the other end of the first branched discharge channel C is connected to the first discharge port of the third head,
the method comprising:
causing a first liquid to flow from the first main supply channel to the first supply port of the first head via the first branched supply channel A;
causing the first liquid to flow from the first discharge port of the first head to the first main discharge channel via the first branched discharge channel A;
causing the first liquid to flow from the first main supply channel to the first supply port of the second head via the first branched supply channel B;
causing the first liquid to flow from the first discharge port of the second head to the first main discharge channel via the first branched discharge channel B;
causing the first liquid to flow from the first main supply channel to the first supply port of the third head via the first branched supply channel C; and
causing the first liquid to flow from the first discharge port of the third head to the first main discharge channel via the first branched discharge channel C.
