Suction-based recovery control method and ink jet printing apparatus
The amount of ink wastage is reduced, even in a case wherein a predetermined amount of air bubbles has grown in a print head at a specific internal temperature and the growth has been settled, and thereafter the temperature in the print head is increased. A suction-based recovery control method, for an ink jet printing apparatus that includes a print head, a temperature detection unit, and a suction-based recovery unit, comprising: a temperature detection step; a temperature judgment step for judging whether the internal temperature of the print head is higher than a reference temperature that is determined based on internal temperatures of the print head that were previously employed; and a suction-based recovery step for permitting the suction-based recovery unit when it is determined at the temperature judgment step that the internal temperature of the print head is higher by the predetermined number of degrees or greater.
