Abstract
An ionographic printer directs a sheet of ions from a source to a charge receptor to create an electrostatic latent image thereon. An ion sheet splitting rod is positioned between the ion source and the charge receptor that splits the ion sheet into two separate streams of ions and insulating wedges serve to focus the separate ion streams into two rows of apertures in an ion control device. The ion streams pass through relatively large apertures having associated therewith a pinch electrode for narrowing the ion streams to a preselected width, and displacing electrodes for positioning the narrowed ion streams within the apertures.
