ABSTRACT:
A recording apparatus has a recording operation that is performed after a disposable liquid ejection recording head is mounted. The discrimination is made as to whether the recording head mounted is proper or not relative to the main assembly to which the recording head is mounted, when the main switch is actuated or the recording head is mounted. The discrimination is made with use of a part of a structure in the recording head: a temperature sensor, a temperature keeping heater, an ejection heater or a driving semiconductor function element, for example. If it is not proper, the recording operation is prevented, and/or the improperness is displayed.
