The utility model relates to a resistance controlled recognition device for ink-jet head. The utility model is used for recognizing whether the ink head is suitable for the main part of an ink-jet printer. The utility model mainly consists of a plurality of recognition units. Each recognition unit comprises a transistor, a first resistance and a second resistance. By adjusting the resistance value of the first resistance and the second resistance, the utility model can provide a plurality of recognition statuses without affecting the prior process procedures, thus avoiding the bad phenomena of repeated identifiers.
