<p>PROBLEM TO BE SOLVED: To reduce power consumption in the case where an inkjet printer executes image formation output.SOLUTION: In order to make the voltage value of voltage input to a head driver become equal or nearly equal to the maximum voltage value of drive voltage required by a piezoelectric element, the voltage output from a constant voltage power supply is transformed according to the use environment and then output to the head driver.</p> |
