Claim 22:
23. The method of flowing the liquid in the line head assembly according to claim 22, wherein each of the first head, the second head and the third head includes:
a second intra-head channel including a second pressure chamber and a second nozzle;
a second supply port connected to one end of the second intra-head channel; and
a second discharge port connected to the other end of the second intra-head channel,
wherein the tank includes:
a second supply channel connected to the second supply port of the first head, the second supply port of the second head and the second supply port of the third head; and
a second discharge channel connected to the second discharge port of the first head, the second discharge port of the second head and the second discharge port of the third head,

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