  • Ink jet printer
    Patent number: 8191985
    Abstract: An ink jet printer printing an image using a plurality of types of color ink. The heat exchanger cools and heats the ink to adjust the temperature of the ink. The heat exchanger has a contact and separate mechanism which, for ink cooling, tightly contacts a radiation section with a heat exchange section and which, for ink heating, separates the radiation section from the heat exchange section.
