Liquid ejecting apparatus, and control method for liquid ejecting apparatus
ActiveUS20150035883A1Minimize power consumptionReduce power consumptionOther printing apparatusRecording headElectricity
In a recording suspension period when a recording head is accelerated or decelerated in a non-recording region on a recording medium, or stops moving in the course of performing a printing process (printing job), a second driving signal is generated from a driving signal generation portion. Second vibration driving pulses of the second driving signal are applied to all piezoelectric elements, so that a vibration operation is performed without ejecting the liquid. Since a second reference potential of the second driving signal is set to be lower than a first reference potential of a first driving signal generated in a recording period as much as possible, a general potential (driving voltage) of the second driving signal is reduced, and reduce power consumption in the recording suspension period is reduced. As a result, it is possible to contribute to the power consumption saving of a printer.
