Abstract:
1. A liquid ejecting apparatus comprising: nozzles which eject liquid; a liquid supply flow path which supplies the liquid from a liquid supply source to the nozzles; a pump which is connected to a separate path branched from a first position in the liquid supply path, wherein the pump suctions the liquid from the first position in the liquid supply flow path and discharges the liquid from the first position into the liquid supply flow path; a one-way valve which is provided at a second position which is further on the upstream side than the first position in the liquid supply flow path, and opened in a case where a pressure chamber, in which a volume changes in accordance with a change in pressure on the downstream side, contracts in accordance with decompression on the downstream side, thereby allowing passage of the liquid from the liquid supply source side to the nozzle side; and a control unit which controls the driving of the pump so as to make the pump suction the liquid in the liquid supply flow path from the first position after making the pump discharge the liquid from the first position into the liquid supply flow path.
