INK-JET RECORDING DEVICE, INK SUPPLY METHOD, POWER SHUTOFF METHOD, AND METHOD FOR SHUTTING OFF TEMPERATURE ADJUSTMENT UNIT OF INK-JET RECORDING DEVICE

摘要

A ink-jet recording device is provided with a head for discharging droplets of ink, a flow path for supplying the ink to the head, said flow path including, in a portion thereof, a storage unit for storing the ink, a storage unit pressure adjustment unit for adjusting the pressure applied to the ink in the storage unit, and a temperature adjustment unit capable of adjusting the temperatures of the flow path and the head independently of each other. The temperature adjustment unit controls the temperatures of the flow path and the head so as to change the ink in the head from a solid to a liquid after the pressure is adjusted by the storage unit pressure adjustment unit so as to change the ink in the flow path from a solid to a liquid.
