• a liquid ejector having a nozzle surface having nozzles from which a liquid is to be ejected;
• a cap configured to perform capping for covering a space in which the nozzles are open;
• a capping mechanism configured to move the cap between a capping position for the capping and a separated position separated from the nozzle surface;
• a cleaning-liquid supply mechanism configured to supply a cleaning liquid into the cap;
• a facing portion configured to face a lip portion of the cap when the cap is in the capping position, the lip portion being an upper end of the cap and having an upper opening for holding the cleaning liquid;
• and
• a controller configured to control the capping mechanism and the cleaning-liquid supply mechanism such that the lip portion faces the facing portion and a predetermined space is provided between the lip portion and the facing portion for the cleaning liquid supplied in the cap to come into contact with the facing portion.
