Abstract:
A recording apparatus using a recording head including a heating element for generating thermal energy thereby performing a recording operation through printing onto a recording medium, comprising:a mounting portion for mounting a recording head;detection means for detecting a resistance value of a resistor formed in the recording head mounted on said mounting portion, said resistor being formed in a same production process as that of the heating element and said resistor having corresponding resistance characteristics to that of the heating element;identification means for identifying whether the recording head mounted on said mounting portion is of a predetermined type based on a result of a determination as to whether a resistance value of the resistor detected by said detection means is within a range of predetermined resistance values;determining means for determining a rank of the resistance value of the resistor in the recording head when identified by said identifying means as being of the predetermined type, based on the resistance value of the resistor detected by said detection means; andcontrol means for controlling the recording operation in accordance with the rank of the resistance value within the range of predetermined resistance values determined by said determining means.
