An inkjet recording apparatus may include a liquid discharge head and a control unit. The liquid discharge head includes a heat generation resistor to generate thermal energy used for discharging liquid and a protection film disposed in at least one of an upper portion and a lower portion of the heat generation resistor. The control unit measures a minimum energy value required by the heat generation resistor to discharge liquid. In addition, the control unit stops discharge operation of the liquid discharge head when at least one of the energy value and a statistical value of the energy value is less than a threshold. |
