Claim:
An ink-jet recording apparatus, comprising: a cartridge mount on which an ink cartridge that stores ink is to be replaceably mounted; a recording head which ejects the ink toward a recording medium; an ink passage through which the ink is supplied from the cartridge mount to the recording head; an ink discharger which discharges the ink from the recording head; and a controller including (a) a cartridge judgment section which judges whether the ink cartridge mounted on the cartridge mount is a subject cartridge that satisfies a predetermined condition or not and (b) a discharger control section which controls the ink discharger to discharge at least the ink in the ink passage when the cartridge judgment section has judged that the ink cartridge mounted on the cartridge mount is the subject cartridge, wherein the discharger control section is configured to control the ink discharger to discharge, from the recording head, at least a part of the ink in the ink cartridge currently mounted on the cartridge mount in addition to all the ink in the ink passage when the cartridge judgment section has judged that the ink cartridge mounted on the cartridge mount is the subject cartridge, and wherein the ink discharger discharges a larger amount of the ink when the cartridge judgment section has judged that the ink cartridge mounted on the cartridge mount is the subject cartridge than when the cartridge judgment section has judged that the ink cartridge mounted on the cartridge mount is not the subject cartridge.
