Abstract
Provided is an ink-replacement method for an inkjet recording apparatus that includes a recording head having an ink ejection surface on which a plurality of nozzles for ejecting ink onto a recording medium is arranged, a sub-tank for temporarily retaining the ink supplied from an ink container, and an ink flow path along which the ink circulates from and to the sub-tank by passing through the recording head. In replacing a first ink present in the ink flow path with a second ink to be newly supplied to the recording head via the ink flow path, when the second ink is caused to flow from the sub-tank into the ink flow path, pulsation is generated in the ink flow path.
