ABSTRACT:
Ink jet deflection is maintained constant regardless of ink temperature by varying the amplitude of pressure oscillation applied to ink in an ejection head (1) as a function of temperature. The pressure oscillation causes the ink to be ejected from the head (1) and separate into droplets. The droplets are charged and electrostatically deflected where it is desired to print a dot. Variation of the amplitude of pressure oscillation changes the shape of the droplets and thereby the amount of charge thereon and the deflection.
