摘要： Provided are a liquid ejection apparatus and a maintenance apparatus capable of suppressing unintended movement of a wiping unit. The maintenance apparatus includes: a wiping unit configured to wipe the ejection opening surface of a liquid ejection head in which ejection openings over a length corresponding to the width of a print medium are formed; and a lock member configured to restrict movement of the wiping unit from a position to which the wiping unit is evacuated from the ejection opening surface.

摘要： There is provided an inkjet printing apparatus including: a print head having an ejection opening surface on which a first ejection opening array capable of ejecting a first ink and a second ejection opening array capable of ejecting a second ink are arranged; a cap member; and a print controller configured to cause the first and the second ejection opening arrays to perform preliminary ejection to an inside of the cap member, and to cause the first ejection opening array to perform preliminary ejection in a first relative position and cause the second ejection opening array to perform preliminary ejection in a second relative position, wherein, on the cap member, a position in which the second ink lands by the preliminary ejection overlaps with an area where the first ink lands by the preliminary ejection.

摘要： A printing apparatus according to the present invention includes a feeding unit, a conveying unit, a printing unit, and a control unit. The control unit performs a successive feeding operation. An operating state of the feeding unit changes between a first operating state and a second operating state in which a feeding stop is more unstable than that in the first operating state, in a period from a start of feeding a printing medium until the printing medium reaches the conveying unit. In the successive feeding operation, a subsequent printing medium is fed without stopping until a leading end of the subsequent printing medium reaches a stoppable position. The stoppable position is arranged on an upstream side of the conveying unit. The subsequent printing medium can be stopped in the first operating state at the stoppable position.
