  • Patent number: 10639899
    Abstract: A liquid ejecting apparatus includes a medium support portion that has a medium support surface for supporting a medium, a liquid ejecting unit that ejects liquid onto the medium supported on the medium support surface through a plurality of nozzles arranged in a nozzle surface, a first cleaning member that wipes the nozzle surface by moving relative to the liquid ejecting unit in a direction along the nozzle surface in a first maintenance operation of discharging the liquid through the nozzles for maintenance of the liquid ejecting unit, and a second cleaning member that removes foreign matters which have adhered to the nozzle surface by moving relative to the liquid ejecting unit in the direction along the nozzle surface in a second maintenance operation of removing the foreign matters.
    Type: Grant
    Filed: March 6, 2019

  • Patent number: 9937721
    Abstract: A printing apparatus includes ejection heads configured to eject a liquid onto a medium, a plurality of sub-units each including an ejection head row configured by a plurality of the ejection heads, and a plurality of maintenance sections configured to sequentially perform maintenance on the sub-units. The plurality of the maintenance sections are configured such that positions of at least two of the plurality of the maintenance sections are aligned with positions of at least two of the plurality of the sub-units, respectively, while the at least two of the plurality of the maintenance sections perform the maintenance.

  • Patent number: 9731511
    Abstract: A printing apparatus includes ejection heads that eject a liquid onto a medium, a plurality of sub-units each including an ejection head row configured by a plurality of the ejection heads, and a plurality of maintenance sections that sequentially perform maintenance on the sub-units. For a head pitch that is a spacing between centers of the ejection head rows, a spacing between centers of mutually adjacent of the maintenance sections is an integer multiple of the product of the head pitch with the number of the ejection head rows provided to each of the sub-units.
