Abstract (en)

[origin: WO9003271A1] In a continuous ink jet printer wherein a jet (J) is fractionatedinto droplets charged in a charge electrode (6) and which then pass between deflection electrodes, a sensor (8) is provided which includes a conductor element (8c) consisting of two parts which are symmetrical with respect to the projectory of the droplets. According to the invention, the device comprises a circuit (9) which determines and processes the first I(t) and second J(t) derivatives with respect to the time of the charge induced in the conductor element by charged droplets (Gc) in order to determine their speed. The device also includes means for regulating the speed of droplets and means for regulating the ink quality.
