Abstract: Method of recording with a stream of marking fluid drops in which a predetermined plurality of successively formed drops in a stream each have the same electrical charge induced therein so that, when subsequently subjected to an electrostatic field, all drops of one commonly charged plurality will impact a record member at approximately the same spot. Drop charges are induced therein by asynchronously applied charging signal levels, each having a duration which is a function of the drop formation frequency and equal to at least two drop periods.
