Patent ID: 7988249

Claim:
A liquid ejecting apparatus comprising: a head having a nozzle; a pressure-changing unit for changing pressure of liquid in the nozzle in such a manner that the liquid is ejected from the nozzle; a first level-data setting unit for setting a selected first level data from a plurality of first level data, based on an ejecting data for a first kind of liquid; a second level-data setting unit for setting a selected second level data from a plurality of second level data, based on an ejecting data for a second kind of liquid; a driving-signal generator for generating a driving signal; and a driving-pulse generator for generating a driving pulse based on the selected first or second level data and the driving signal, wherein a number of levels of the plurality of first level data and a number of levels of the plurality of second level data are different from each other, the driving-signal generator is adapted to generate a first driving signal and a second driving signal, the driving-pulse generator is adapted to generate a first driving pulse based on the selected first level data and the first driving signal and the second driving signal, the driving-pulse generator is adapted to generate a second driving pulse based on the selected second level data and the first driving signal and the second driving signal, the first driving signal and the second driving signal are periodical signals having a same period, the first driving signal includes in one period thereof a plurality of pulse-waves, and the second driving signal includes in one period thereof a plurality of pulse-waves.
