Abstract:
1. A liquid droplet jetting apparatus which jets liquid droplets of a liquid, comprising: a liquid droplet jetting head which has a liquid droplet jetting surface on which a plurality of nozzles are open to jet the liquid droplets of the liquid; a cap member which covers openings of the nozzles of the liquid droplet jetting head, which is formed with a suction port, and which has a contact surface to make contact with the liquid droplet jetting surface; a moving mechanism which moves the cap member to make contact with and separate from the liquid droplet jetting surface; a purge mechanism which is connected to the suction port of the cap member and which performs purge to discharge the liquid from the nozzles in a state in which the cap member is brought in contact with the liquid droplet jetting surface; and a controller which is configured to control the liquid droplet jetting head, the moving mechanism, and the purge mechanism, wherein: the cap member is tiltable such that the contact surface is inclined with respect to the liquid droplet jetting surface when the cap member is separated from the liquid droplet jetting surface; after performing the purge by controlling the moving mechanism and the purge mechanism, the controller controls the moving mechanism such that the cap member is separated from the liquid droplet jetting surface in an inclined state in which the contact surface is inclined with respect to the liquid droplet jetting surface and the controller controls the liquid droplet jetting head such that first flashing is performed to discharge the liquid by jetting the liquid droplets from the plurality of nozzles respectively; and in the first flashing, the controller controls the liquid droplet jetting head such that a discharge amount from a first nozzle of the nozzles is greater than a discharge amount from a second nozzle of the nozzles, the second nozzle being disposed farther than the first nozzle from a position, on the liquid droplet jetting surface, at which a part of the contact surface of the cap member is lastly separated from the liquid droplet jetting surface when the cap member in the inclined state is separated from the liquid droplet jetting surface.
