Abstract
An ink-jet cartridge constructed with an inkjet printing head and an ink tank is positioned and filed on an upper surface of a base in a condition where ink ejection opening forming surface of the head is oriented upwardly. The ink ejection opening forming surface is contacted with a lower end portion of an elastic member which is movable in a direction of arrow a or arrow b. By sucking through suction hole or the like of the elastic member, vacuum pressure is introduced into a space between the elastic member and the ink ejection opening forming surface to discharge bubbles residing in liquid passages or floating up to the ink ejection openings.
