摘要

An ink jet apparatus performs recording by ejecting from the head portion the ink which is contained in an exchangeable ink jet cartridge for the apparatus to form desired images on a recording medium. The apparatus performs suction recovery operation for the head portion in the non-installation state where the ink jet cartridge is removed from the apparatus. With this suction recovery, all the ink in the ink passage from the installation portion for the ink jet cartridge to the recording head is exhausted from the head portion; hence making it possible to remove bubbles remaining in ink totally and easily without any additional components and any resultant contamination in the nozzles provided for the recording head.
