1. A liquid ejecting apparatus comprising:
nozzles configured to eject a liquid in an ejection direction;
a common liquid chamber that communicates with the nozzles and extends in a first direction orthogonal to the ejection direction;
a filter that partitions the common liquid chamber into an upstream chamber and a downstream chamber;
an inlet for introducing the liquid into the upstream chamber;
an outlet for causing the liquid to flow out from the upstream chamber;
a liquid storage section configured to store the liquid;
a supply flow path that causes the inlet to communicate with the liquid storage section; and
a recovery flow path that causes the outlet to communicate with the liquid storage section, wherein
a beam portion that couples a pair of inner walls for defining the downstream chamber is provided inside the downstream chamber,
the pair of inner walls are separated in a direction intersecting with the first direction when viewed in the ejection direction,
a pressurization discharge operation for discharging the liquid from the nozzles by pressurizing the supply flow path and a circulation operation for circulating the liquid in a circulation path including the liquid storage section, the supply flow path, the common liquid chamber, and the recovery flow path, in order of the liquid storage section, the supply flow path, the common liquid chamber, the recovery flow path, and the liquid storage section are performed, and
in a filling process of filling the circulation path with the liquid, the circulation operation is performed after the pressurization discharge operation is performed.
