ABSTRACT:
A high speed digital ionographic printer employing an ion deposition control bar interposed between the ion source and the movable charge receptor, the bar having n parallel rows of apertures each with a ring-like control electrode, the aperture rows being perpendicular to the direction of movement of the charge receptor, a combination of n line buffers and n shift registers associated with control switches for providing preset negative or positive modulating potentials to the aperture control electrodes in accordance with the image pixel content of the n lines of image signals currently in the shift registers to provide controlled ion flow through the apertures with partial ion deposition on the charge receptor of n lines at once, the block of n image lines being stepped by one each time the charge receptor moves one line.
