Abstract
A printing sub-system including same including a pixilated photoconductive member (such as a photobelt) is disclosed. Electrically isolated cells hold surface application material above the photoconductor. The surface application material is first charged. Charge on the surface application material in an individual cell may then be discharged by exposure of a region of the photoconductor proximate that cell to light from an optical addressing system. The surface application material is brought into proximity of an image receiving member such as paper, which is either charged or proximate a charge source. Charged surface application material in a cell may then be electrostatically transferred from the cell onto the image receiving member, while discharged surface application material remains in the cell. The subsystem may form a part of a complete printing system using many existing components. Among other advantages, viscous liquid surface application material may thereby be printed.
