The invention has been made to prevent ink adhesion or an ink discharge failure caused by ink adhesion due to evaporation of volatile components of ink which occurs when the ink receptor of a printhead is exposed to air for a long time. If an inkjet printhead and an ink tank containing ink to be supplied to the printhead are attached to a carriage, the ink supply port of the ink tank is pressed to the ink receptor of the printhead. In this arrangement, the presence/absence of attachment of the ink tank to the carriage is detected. If it is detected that the ink tank is not attached to the carriage, a suction operation for the printhead is performed and controlled to suck out ink from the nozzles of the printhead.
A printing apparatus including a printhead having at least one nozzle array formed by a plurality of nozzles for discharging ink, and a carriage to which the printhead and at least one ink tank for supplying ink to the printhead are mounted, wherein a filter member is arranged between the ink tank and the printhead, the apparatus comprising:
A control method for a printing apparatus including a printhead having a nozzle surface with at least one nozzle array formed by a plurality of nozzles for discharging ink, and a carriage to which the printhead and at least one ink tank for supplying ink to the printhead are mounted, wherein a filter member is arranged between the ink tank and the printhead, the method comprising:
