ABSTRACT:
A toner jet printer and method of use for printing images by manipulating individual toner particles using two-dimensional print cell arrays built by micro electro mechanical systems (MEMS) technologies. Toner particles are positioned by aerodynamic forces controlled by microvalves within each print cell by either selective or nonselective filling. If selectively filled, each cell is then heated or subjected to an aerodynamic force to eject the toner particles onto a paper substrate. If non-selectively filled, only those print cells corresponding to an intended image are addressed electronically to eject a toner particle from an addressed cell by aerodynamic forces controlled by valve actuation or by heating the print cell. Single color or multiple color printing can be achieved using the same cell array.
