Abstract
Liquid is sent from a liquid retainer to a liquid ejection head via a liquid supply line by pressurization force generated by a pressurization device that is driven by a driver. A method for cleaning a liquid ejection apparatus includes drawing the liquid from the liquid ejection head through a nozzle by a suction device; and obtaining a liquid remaining amount of the liquid retainer. The method further includes determining an operational speed of the driver in correspondence with a result of the calculation; and operating the driver at the determined operational speed when drawing the liquid by the suction device. Thus, liquid is consumed completely without being wasted.
