Abstract:
A recording device comprising:a recording element; a drive circuit that drives the recording element; a first sensor that outputs a signal corresponding to a temperature around at least one of the recording element and the drive circuit; a power switch that is turned ON and OFF, wherein when the power switch is ON, one of a first driving voltage and a second driving voltage lower than the first driving voltage is applied to the first sensor, wherein the first sensor outputs a first signal corresponding to a first temperature when the first sensor is applied with the first driving voltage; a memory that stores a first data relating to the first signal; a calculation unit that obtains data relating to the signal in accordance with the first data stored in the memory, the signal being output when the first sensor is applied with the second driving voltage; and a control circuit that regulates the drive circuit to drive the recording element when the data obtained by the calculation unit corresponds to a predetermined second temperature higher than the first temperature.
