  • Publication number: 20230264476
    Abstract: Provided is a method of controlling a liquid ejecting device. The liquid ejecting device includes a liquid ejecting unit configured to eject a liquid containing an inorganic pigment from a nozzle provided at a nozzle surface, a wiper unit including a band-like member configured to absorb the liquid and a pressing unit configured to move the band-like member in a first direction, and a wiper moving unit configured to move the wiper unit in a second direction opposite to the first direction to wipe the nozzle surface using the band-like member. The method includes performing first wiping in which, to wipe the nozzle surface, the wiper moving unit moves the wiper unit at a first velocity while the pressing unit moves the band-like member at a first velocity.

  • Patent number: 11135849
    Abstract: A liquid ejecting apparatus includes a liquid ejector that ejects a liquid from a nozzle, a wiping mechanism that wipes a nozzle surface on which a plurality of nozzles is disposed with a wiping member, and a wiping-liquid supply mechanism that supplies a wiping liquid to the wiping member. The liquid ejecting apparatus is configured to perform wet-wiping of wiping the nozzle surface in a state where the wiping member has absorbed the wiping liquid and is configured to change a supply amount of the wiping liquid when the wiping member wipes the nozzle surface.

  • Patent number: 9511590
    Abstract: A liquid supply apparatus includes plural outlet flow paths respectively connected to the plural mounting units in which plural liquid storing bodies are respectively mounted, a supply flow path to which the plural outlet flow paths are connected, a switching unit capable of switching a communication status of each outlet flow path with the supply flow path, and a pressurizing and supplying unit that pressurizes and supplies liquid in the liquid storing bodies to the supply flow path. If the amount of liquid remaining in the liquid storing body communicating with one of the outlet flow paths is less than or equal to a second threshold greater than a first threshold, liquid in the liquid storing body communicating with another outlet flow path different from the one outlet flow path is made ready to be pressurized and supplied.

  • Patent number: 9427974
    Abstract: A liquid supply system includes a common mounting portion into which a first liquid storage body capable of storing a liquid and a substitute mounting body which is connected to a second liquid storage body capable of storing a liquid can be exchangeably mounted, a mounting target detection unit capable of detecting whether or not the first liquid storage body and the substitute mounting body are mounted to the common mounting portion, a pressurization supply unit which supplies the liquid which is stored in the second liquid storage body to the substitute mounting body under pressure, and a control unit which drives the pressure supply unit when a plurality of control conditions are satisfied.
