  • Patent number: 11858278
    Abstract: A liquid ejecting apparatus includes a liquid supplying apparatus. The liquid supplying apparatus includes a supply flow passage that is in communication with a liquid ejecting head configured to eject liquid, a first supply flow passage for communication between a first liquid container and the supply flow passage, the first liquid container containing liquid, and a second supply flow passage for communication between a second liquid container and the supply flow passage, the second liquid container containing the same kind of liquid as the liquid contained in the first liquid container, a switching unit configured to switch a flow passage that is in communication with the supply flow passage, between the first supply flow passage and the second supply flow passage, and a movement restriction unit configured to, linked with switching by the switching unit, restrict movement of the first liquid container and the second liquid container selectively.

  • Patent number: 11298951
    Abstract: 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.
