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.

Abstract: A liquid supply mechanism includes a sub-tank that supplies liquid to a liquid ejection head and a liquid replenishing mechanism that suctions liquid from a main tank into the sub-tank. The liquid replenishing mechanism has a diaphragm, a biasing member, and a drive member. The diaphragm has a movable portion and a mounting portion and closes one end of a liquid container chamber provided on the sub-tank. The biasing member biases the diaphragm in a first direction in which a volume of the liquid container chamber is decreased. The drive member pulls the diaphragm in a second direction in which the volume of the liquid container chamber is increased. The movable portion of the diaphragm can move in the first direction and the second direction. The movable portion has a first portion, which is flexible, and a second portion that retains its shape when the liquid container chamber is pressurized.
