ABSTRACT:
An ink jet printer in which the nozzle for emitting a stream of ink drops, the charge electrode for charging ink drops in accordance with signals to be recorded, and the deflection electrodes for providing an electric field therebetween to deflect ink drops in accordance with the magnitude of the charges on the drops, are mounted on a carrier which moves relative to an ink drop record receiving media for forming images indicative of the signals on the deflected ink drops. To compensate for the inclination of the image formed by the carrier movement relative to the recording media, a voltage gradient or difference is applied across at least one of the deflection electrodes so as to effect electric field distortion intermediate the electrodes to thereby compensate for the slant due to carrier motion. The amount of distortion is controlled by monitoring the carrier velocity and automatically feeding back a signal to the distortion creating voltage difference to control the voltage difference dependent upon carrier velocity.
