Title: Innovations of William L. King

Introduction

William L. King is a notable inventor based in Rochester, NY (US), recognized for his contributions to fluid ejection systems. He holds a total of six patents, showcasing his expertise and innovative spirit in the field.

Latest Patents

Among his latest patents is a method for charging and priming fluid ejector heads. This priming method divides the priming schedule for the ink ejector into two parts: charging and priming. Priming is a high negative pressure pulse of short duration that minimizes print quality defects and removes air bubbles in the printhead. Charging, on the other hand, is a low negative pressure profile of longer duration that prepares a dry or new printhead for use, minimizing discontinuities and ink flow when a new ink jet cartridge is installed. Another significant patent is a method and device to prevent foreign metallic object damage in fluid ejection systems using microwave dryers. This invention includes a metal detection system that reduces damage caused by the introduction of metal into microwave dryers. One embodiment of this invention stops paper pick-up rollers and feed rollers when metal is detected, while another turns off the electromagnetic field in the microwave dryer when metal is present in the drying cavity.
