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.

A liquid ejection device includes a liquid ejection unit configured to perform printing by ejecting a liquid from a nozzle onto a medium, a maintenance unit configured to perform maintenance of the liquid ejection unit, a determination unit configured to determine whether printing data for the printing is ruled-line data including a vertical ruled line or non-ruled-line data not including the vertical ruled line, a storage unit configured to store a determination result obtained by the determination unit, and a control unit. The control unit changes intensity of the maintenance in accordance with a frequency of the ruled-line data included in the determination result stored in the storage unit.

A liquid discharge system includes: a head (300) including: a nozzle (302) from which a liquid is to be discharged; a liquid chamber (311) communicating with the nozzle through a communication port; a nozzle face (301) on which the nozzle is formed; and a valve (304) configured to open or close the communication port; and a cleaner (708) including a cleaning nozzle (201) to supply a cleaning liquid to the nozzle face, wherein the cleaner supplies the cleaning liquid from the cleaning nozzle to the nozzle face in a state where the valve has closed the communication port.

A server connected via a network to a printing apparatus including a plurality of nozzles includes an acquisition unit that acquires nozzle information indicating a state of the plurality of nozzles, a determination unit that determines, among the plurality of nozzles, a nozzle to be cleaned based on the nozzle information acquired by the acquisition unit, and an instruction unit that instructs the printing apparatus to perform cleaning on the nozzle to be cleaned determined by the determination unit.

A recording device includes a head including a plurality of nozzles that are arranged at predetermined intervals in a first direction, the plurality of nozzles being configured to eject liquid, and a controller. The controller is configured to, in a case where the number of the abnormal nozzles among the plurality of nozzles is equal to or greater than the predetermined number and the number of the abnormal nozzles, among a part of the plurality of nozzles in which an interval in the first direction is a preset interval longer than the predetermined interval, is less than the predetermined number, cause the head to eject liquid from the part of nozzles to record an image with a resolution in which a resolution in the first direction is lower than a resolution corresponding to the predetermined interval.

A printing apparatus including a print head ejecting ink, flowing from a first channel into a pressure chamber, from a nozzle, by driving an ejection energy generating element in the pressure chamber, a circulation pump circulates the ink in a circulation channel including the first channel, the pressure chamber, and a second channel that flows the ink from inside the pressure chamber to the outside, a wiping unit with a cleaning member that wipes an ejection port surface of an ejection port and a winding member that winds the cleaning member, and a control unit controls a cleaning operation in which the wiping unit wipes the ejection port surface. When the cleaning operation is performed after the circulation pump is stopped, the cleaning operation is changed based on an elapsed time from the time the circulation pump stopped driving, and the cleaning operation is controlled based on the elapsed time.
