Claim:
1. An ink jet recording apparatus comprising: a recording head configured to eject ink; a buffer tank configured to temporarily store the ink; a mounting unit to which a main tank that stores the ink is capable of being mounted, the main tank having a first supply port from which the ink is supplied to the recording head and a second supply port from which the ink is supplied to the buffer tank; a detecting unit configured to detect an ink volume in the main tank; and a control unit configured to perform a discharge operation to discharge the ink in the buffer tank from the recording head via the main tank in a pre-transportation process in the ink jet recording apparatus, wherein the control unit prompts a user to replace the main tank without performing the discharge operation if the ink volume detected by the detecting unit is smaller than a threshold value.
