  • the ink emission is conducted by the second voltage pulse while the meniscus is retracted by the application of the first voltage pulse, the amount of ink emission is reduced in comparison with the absence of the first voltage pulse. Also the emission speed increases due to the presence of a meniscus advancing force, caused by the surface tension of the meniscus in the retracted state.
  • the piezoelectric element shows a larger displacement for the application of a given voltage, at a higher temperature.
  • the ink viscosity becomes lower at a higher temperature.
  • Japanese Patent Publications (unexamined) Nos. 27210/1980, 65566/1980, 65567/1980 and 60261/1981 disclose modification of the driving conditions of the piezoelectric element according to the temperature.

  • the second voltage pulse B for ink droplet emission is applied in succession to the first voltage pulse A as shown in Fig. 1.
  • Said second voltage pulse B is directed same as the polarization direction of the piezoelectric element 5, thus serving to decrease the volume of the pressure chamber, constituted by a portion of the liquid path 4 surrounded by the piezoelectric element 5.
  • Fig. 3 shows the temperature-dependent change in the amount of meniscus retraction caused by the first voltage pulse A, wherein the ordinate indicates the amount of said retraction in micrometers while the abscissa indicates the temperature (°C).
