  • Publication number: 20190143700
    Abstract: An inkjet printing apparatus includes a printhead having an ejection orifice surface on which ejection orifices for ejecting ink are arranged, where the printhead performs a printing operation in a printing area; a carriage including the printhead, and movable in a first direction; a cap for covering the ejection orifice surface; and a wiper that wipes the ejection orifice surface. The cap is movable, by a movement of the carriage, to a first position, and to a second position farther from the printing area along the first direction. At the second position, the cap can rise and lower to a capping position at which the cap abuts the ejection orifice surface, and to a separated position at which the cap does not abut the ejection orifice surface. The wiper wipes the ejection orifice surface when the cap is at the second position and at the separated position.
