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.

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.
