ABSTRACT:
An ink jet recording apparatus incorporating a plurality of ink tanks that is independently exchangeable. An amount of ink suction for a suction recovery operation is changed and controlled based on the ink tank being exchanged. In this way, a small-sized apparatus operating at a low running cost is possible by saving and decreasing the ink amount discharged by controlling the ink discharge more than necessary during the suction recovery process after exchanging the ink tank.
