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.

Method of controlling a liquid ejecting device and liquid ejecting device

A liquid ejecting apparatus includes a liquid ejecting portion that has a supply port, a second discharge port, a plurality of nozzles, and a nozzle surface on which a plurality of the nozzles are open, and that discharges the liquid from the nozzles, a liquid supply flow path coupled to the supply port so that the liquid is supplied to the liquid ejecting portion, and a liquid return flow path coupled to the second discharge port so that the liquid supplied to the liquid ejecting portion is returned to the liquid supply flow path, in which a pressure lowering operation of lowering a pressure in the liquid ejecting portion is performed in a state where a flow of the liquid in the liquid return flow path is blocked after performing a pressurization discharge operation of pressurizing the liquid in the liquid ejecting portion and discharging the liquid from the nozzle.

Liquid ejecting apparatus and maintenance method of liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting portion having a filter configured to filter a supplied liquid and eject the liquid filtered by the filter from nozzles, a liquid ejecting portion holding portion replaceably holding the liquid ejecting portion, a liquid supply flow channel coupled to the liquid ejecting portion so as to supply the liquid to the liquid ejecting portion, a flow mechanism configured to flow the liquid, and a control portion configured to drive the flow mechanism to cause the liquid to flow in the liquid supply flow channel toward the liquid ejecting portion in replacement of the liquid ejecting portion.
