Abstract
A particular ink tank, and therefore its characteristics, are determined by detecting the existence or absence of magnets at predetermined positions on the ink tank. The detection of the magnets is performed by hall effect sensors located on an ink tank holder of an image recording apparatus when the ink tank is positioned in the ink tank holder.
