Liquid ejecting apparatus, and control method for liquid ejecting apparatus

摘要

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.

1. A liquid ejecting apparatus comprising:
a liquid ejecting head that ejects a liquid in a pressure chamber from a nozzle through driving of a pressure generator, the liquid ejecting head including a plurality of nozzles and a plurality of pressure generators; and a driving signal generator that generates a driving signal for driving the pressure generator, wherein the driving signal generator can generate:
a first driving signal specific for each pressure generator, the first driving signal is applied to the specific pressure generator in a period when the liquid is ejected onto a landing target, anda second driving signal which is applied to the pressure generator in a period when the liquid is not ejected onto the landing target when the liquid ejecting head is outside of the landing target, the second driving signal having a vibration contraction maintaining waveform part set at a vibration contraction potential, and wherein a second reference potential which is used as a reference of a potential change in the second driving signal and the vibration contraction potential are each set to be lower than a first reference potential which is used as a reference of a potential change in the first driving signal.
