Abstract: THERMAL DROP-ON-DEMAND INK JET PRINT HEAD A thermal drop-on-demand ink jet print head in which an array of heating means is provided on one surface of a substrate member. A common electrode provides electrical contact to the heating means, and an array of data electrodes provides electrical contact to individual ones of the heating means. An array of feed through conductors is provided which pass through to the opposite surface of the substrate member to provide electrical contact between one of the data electrodes and one of an array of conductors leading to spaced solder pads on the opposite surface of the substrate member. A nozzle plate is mounted adjacent to the substrate member with a nozzle adjacent to each of the heating means so that, upon connection of an electrical signal to one of the solder pads, the corresponding heating means is energized and a drop of ink is ejected from the adjacent nozzle. Various embodiments are described in which multiplexing techniques are used to achieve a reduction in electrical connections and electronic drivers.

Abstract: A thermal drop-on-demand ink jet print head in which conductor electrodes are formed on opposed surfaces of a print head substrate and extend to the edge of the substrate. An array of heater elements is formed on the edge of the substrate in electrical contact with the conductor electrodes. A nozzle plate is mounted with a nozzle aligned with each heater element, and a manifold is positioned to provide ink to the space between the nozzle plate and the edge of the substrate so that a drop of ink can be ejected from the nozzle each time the associated heater element is energized with a data pulse applied to a selected one of the conductor electrodes.
