A method and apparatus relating to a unique printhead configuration is disclosed. The printhead configuration is based on a coplanar arrangement of two sets of electrodes. The electrodes are electrically separated from each other by a dielectric layer, and together create a matrix of charge generating sites. Such a printhead has a very low internal capacitance and therefore is suitable for high speed and high resolution printing.

Coplanar thin film printhead

A modular printhead is disclosed having the ability to separate, leaving a first collection of predetermined layers relatively permanently affixed to a print engine while a second collection of predetermined layers resides in a relatively disposable component thereof. The modular printhead includes a first printhead component having at least a first electrode and a second electrode. There is additionally a second component of the printhead. The second component can have a third electrode. The first printhead component of the printhead demountably presses against the second component, held in place by at least one fastening mechanism.
