Patent ID: 7988279

Claim:
An ink-discharging apparatus comprising: a discharge head having a nozzle to discharge an ink, of which viscosity is increased when a predetermined energy ray is irradiated to the ink, onto a recording medium; a first light source which radiates the predetermined energy ray; and an irradiation mechanism configured to irradiate the nozzle with an energy ray for increasing the viscosity of the ink at the nozzle; a controller configured to control the discharge head and the irradiation mechanism and to receive an image-recording instruction inputted to the ink-discharging apparatus, wherein the controller controls the irradiation mechanism to irradiate the nozzle with the energy ray when a predetermined time has elapsed since the discharge head last discharged the ink, and wherein the controller controls the irradiation mechanism not to irradiate the nozzle with the energy ray when the controller receives the image-recording instruction before the predetermined time has elapsed since the discharge head last discharged the ink.
