A liquid ejecting system includes a liquid storage mechanism including a liquid storage portion provided in a liquid supply channel that can supply liquid in a liquid supply source to a liquid ejecting portion, and a second negative pressure larger than a first negative pressure is generated in the liquid storage portion when a storage amount of the liquid in the liquid storage portion becomes smaller than a set predetermined amount, the first negative pressure being a negative pressure that is generated in the liquid supply source when a remaining amount of the liquid in the liquid supply source becomes small.

Liquid ejecting system and liquid storage mechanism

A liquid circulation mechanism includes a first storage portion configured to store liquid to be supplied to a liquid discharging head, a second storage portion configured to store the liquid collected from the liquid discharging head, a third storage portion configured to store the liquid between the second storage portion and the first storage portion, a first check valve allowing flow of the liquid from the second storage portion to the third storage portion while regulating flow of the liquid from the third storage portion to the second storage portion, in the second collection flow path, and a second check valve allowing flow of the liquid from the third storage portion to the first storage portion while regulating flow of the liquid from the first storage portion to the third storage portion, in the third collection flow path.

Liquid circulation mechanism, liquid circulation device, and liquid discharging apparatus

A liquid ejecting apparatus including a liquid ejecting portion that ejects a liquid, a liquid supply flow path that supplies the liquid accommodated in a liquid supply source to the liquid ejecting portion, a storage portion that is provided in the liquid supply flow path and that stores the liquid, a pressure mechanism that changes a volume of the storage portion by making pressure act thereon, a liquid filling mechanism that fills the liquid inside the liquid supply source into the liquid supply flow path, and a control portion that fills the liquid into the liquid supply flow path while the volume of the storage portion is, by making pressure act on the flexible portion, made smaller than when the pressure does not act on the flexible portion, and after the filling, ends a state in which the pressure is made to act on the flexible portion.
