ABSTRACT:
Disclosed is an ink jet printer in which the temperature detecting circuit 8 is arranged between the thermistor 3 mounted on the ink jet head 2 and the flexible cable 7 for transmitting the signal output from the thermistor 3 to the CPU 30, and the analog signal, which is the voltage value corresponding to the temperature of the ink jet head 2, from the thermistor 3 is converted into the pulse signal (digital signal) by the temperature detecting circuit 8, the digital signal being output to the CPU 30 through the flexible cable 7, thereby the drive voltage of the ink jet head 2 is controlled according to the viscosity change of the ink occurring by the temperature change of the ink jet head 2 itself or the circumstance surrounding the ink jet head 2, by detecting the temperature of the ink jet head 2 through the thermistor 3.
