Print element for Xerox thermal ink-jet print cartridge

Xerox thermal ink jet print cartridges utilize a print element fabricated via VLSI technology. This fabrication process enables high productivity and precise dimensional control as well as the required electronic functionality. However, modifications to the device geometry involve a complex cycle of mask generation, VLSI fabrication, and assembly. The development of the print element is assisted by the use of experimental wafers which contain TIJ devices with variations in many important geometrical parameters. Analysis of data from measurements on these experimental geometries leads to designs.
