ABSTRACT:
A recording apparatus includes a head that discharges ink and a head driving circuit that generates a switching signal. The recording apparatus further includes a switching signal generating unit that generates and outputs a switching signal, a first switch that is turned on or off based on the switching signal and a second switch that is turned on or off based on the switching signal. A first DC voltage is converted into a second DC voltage by switching one of the first switch and the second switch based on the switching signal, and the second DC voltage is supplied to the head driving circuit. The first switch and the second switch may be turned on or off based on the detected temperature of the head or ink in the head.
