Abstract

PURPOSE:To provide the titled ink supply device that stabilizes the formation of ink drops at a multi-type ink discharge openings by communicating an ink tank and each of heads and costituting the ink supply system so that pressure application to he tank supplies ink to all heads. CONSTITUTION:With a valve 107 opened and a valve 110 closed a first tank 102 is pressurized with a pump 101 to suppy ink from the tank 102 to ink jet heads 104 and 104' through pipes 103 and 103'. By this pressurizing the ink flow channel from the hads 104 and 104', pipes 103 and 103' and 106, etc., to a second ink jet head 108 is filled with ink. Next, the pressurizing is stopped to open the valve 110, which makes ink levels of both tanks 102 and 108 equal.
