摘要： An inkjet printer includes a first light applicator disposed in a second scanning direction relative to a recording head. The first light applicator includes a first upstream light source group at a location corresponding to a location of the recording head in a movement direction of a recording medium, and a first downstream light source group on a downstream side in the movement direction of the recording medium relative to the recording head. The inkjet printer turns off the first upstream light source group and turns on the first downstream light source group during movement of a carriage in a first scanning direction and discharge of first ink from the recording head, and turns on the first upstream light source group and the first downstream light source group during movement of the carriage in the second scanning direction after discharge of the first ink.

摘要： A photo-curing inkjet printer includes a bed, a discharger, a light applicator, and a conveyor. The bed includes a printable region defined in advance. A substrate is placed on the bed. The discharger discharges photo-curable ink. The light applicator applies light. The conveyor conveys one of the bed and the discharger relative to the other one of the bed and the discharger in a conveyance direction. The discharger includes a row of nozzles aligned in the conveyance direction. The nozzles discharge the photo-curable ink. A length of the bed measured from a start end of the bed to a start end of the printable region is longer in the conveyance direction than a length calculated by subtracting a maximum pass width from a length of the row of nozzles of the discharger.

摘要： A printing apparatus includes a feeder that feeds a medium in a feeding direction, a head including a row of nozzles arranged side by side in the feeding direction and movable in a scanning direction, an irradiator that radiates light onto a region longer in the feeding direction than the nozzle row and that is movable in the scanning direction together with the head, and a controller that alternatingly causes the head to move in the scanning direction and concurrently the nozzles to discharge ink while causing the irradiator to radiate the light, and the feeder to feed the medium in the feeding direction. The controller is capable of dividing the nozzle row into an upstream-side nozzle row and a downstream-side nozzle row located on a downstream side in the feeding direction from the upstream-side nozzle row, and individually controlling discharge of ink from the nozzles of each of the upstream-side nozzle row and the downstream-side nozzle row. The controller is capable of dividing the irradiator into an upstream-side irradiator, an intermediate irradiator adjacent to the upstream-side irradiator on a downstream side in the feeding direction, and a printless region irradiator adjacent to the intermediate irradiator on a downstream side in the feeding direction, and individually controlling lighting and extinguishing of each of the irradiators defined by the division.

摘要： 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.
