Abstract

This paper describes the measurement of thermal inkjet driver chip has a number of uses in the technology: D-Flip Flop logic control circuit on printhead verify for addressing nozzles by de-multiplexer FPGA device pre-check, high voltage NMOS driver characteristic by HP4145B instrument, OES/TTRI setting design goals to monitor droplet orbit, the stream of frozen images was then acquired by a CCD camera, the evolution of droplet velocity for different time frames, droplet trajectory provides an overall picture of the droplet ejection trajectory, while the droplet ejection sequence provides the more detail evolution of droplet formation and ejection. Droplet properties, such as ejection speed, droplet size, directionality, satellite droplets, flying distance and frequency response, we introduce some of the data showing current trends in thermal inkjet performance and life. The droplet ejection of our multiplexer printhead with 12 um diameter diameter nozzle has been characterized at a frequency over 19.8 kHz, 5 pL of ejected droplet volume.
