Abstract:
There is provided an inkjet printing apparatus having a configuration of capping and sucking an ejection opening surface for ejecting a plurality of types of inks by using one cap member, in which the inks in the cap member can be sucked and removed evenly. To achieved this, a cap member is provided with a suction opening for externally discharging ink absorbed by an absorber in the cap member. The suction opening is formed in a position where the suction opening does not face first ejection openings for ejecting ink that may not easily stagnate and faces the second ejection openings for ejecting ink that may easily stagnate in a case where the cap member caps an ejection opening surface.

Claim (Index 1):
An inkjet printing apparatus comprising:\n a print head having an ejection opening surface on which first ejection openings for ejecting a first ink and second ejection openings for ejecting a second ink are arranged so as to correspond to the width of a print medium, the second ink having a higher viscosity compared to the first ink; a cap member capable of capping the ejection opening surface; an absorber located in the cap member for absorbing inks discharged from the first ejection openings and the second ejection openings; a suction opening formed on the cap member for discharging inks absorbed by the absorber: the suction opening being formed in a position where the suction opening does not face a region in which the first ejection openings are arranged and faces a region in which the second ejection openings are arranged in a case where the cap member caps the ejection opening surface; and a maintenance unit configured to maintain ejection performance of the first ejection openings and the second ejection openings, wherein in a state where the ejection opening surface and the cap member are located in a predetermined relative position, the maintenance unit performs preliminary ejecting operation for ejecting the first ink and the second ink respectively from the first ejection openings and the second ejection openings and suction operation for discharging inks absorbed by the absorber in the preliminary ejecting operation from the suction opening.
