ABSTRACT:
A method of producing an electrostatic image along scan lines of a recording medium with recording means including a series of stylus electrodes arranged in a longitudinally extending array and divided into two groups, with the stylus members of each group being connected in parallel with one another along the array. A series of complementary electrodes is arranged in a longitudinally extending array and cooperates with sets of stylus electrodes for depositing a charge pattern upon a selected region of recording medium when the sets of stylus electrodes and selected complementary electrodes are pulsed contemporaneously. The method comprises the steps of delivering data, comprising a writing potential or a non-writing potential, to the stylus electrodes of both groups, and overriding certain of the data with a non-writing potential for defining the sets of stylus electrodes within the groups.
