  • Patent number: 10369796
    Abstract: A printing apparatus includes: a printhead configured to discharge ink; a carriage, on which the printhead is mounted, configured to move in a first direction such that the printhead moves across a printing region where a printing operation by the printhead is performed and a standby region adjacent to the printing region; a cap arranged in the standby region and configured to suck the ink from the printhead; and a wiper configured to perform wiping for the printhead. The cap can be displaced to a first position and a second position farther from the printing region in the first direction than the first position. At the second position, the cap can be displaced to an upper position to cap the printhead and a lower position to be separated from the printhead allowing the wiper to wipe the printhead.
