Elongated fluid jet printing apparatus

摘要

The individual elements of an elongated array of fluid jet orifices are independently positioned with respect to the individual elements of a second elongated array of individual charging electrodes thus relaxing critical mechanical manufacture and assembly tolerances therebetween. The number of fluid jet orifices is substantially greater than the number of independent charging electrodes so as to permit this independent positioning and the enhanced printing resolution of the apparatus is made possible primarily by the lesser density of individual electrodes in the electrode array.
