  • Printing device including light radiation device with independently controlled radiation portions
    Patent number: 11926147
    Abstract: In a light radiation device including an upstream radiation portion, a middle radiation portion and a downstream radiation portion, the upstream radiation portion overlaps a nozzle array in a transportation direction. A controller includes a path controller to control a path operation of ejecting ink from the nozzle array onto a medium while moving a recording head and the light radiation device in a scanning direction, a transportation controller to control a transportation operation of, after the path operation, transporting the medium downstream in the transportation direction by a distance shorter than a length in the transportation direction of the nozzle array, and a first light radiation controller to control the light radiation device, during the path operation by the path controller, to turn on the upstream radiation portion and the downstream radiation portion and to turn off the middle radiation portion.
