Abstract
The inkjet printing apparatus includes: a printing unit to eject ink; a wiping unit capable of wiping an ejection opening surface by moving relative to the ejection opening surface with an opening, adapted to be in contact with the ejection opening surface, put in contact with the ejection opening surface; a suction unit connected to the wiping unit and configured to apply negative pressure to the ejection opening surface via the opening; a moving unit to move the wiping unit relative to the ejection opening surface; and a control unit to perform suction wiping operation by wiping the ejection opening surface with the wiping unit while applying negative pressure to the ejection opening surface. The control unit determines the timing to perform the suction wiping operation, and, according to the timing, determines a moving speed of the moving unit and a pressure value caused by the suction unit.
