Title: Innovations of James R. Pickell in Ink Jet Printing Technology
Introduction
James R. Pickell is an accomplished inventor based in Bartlett, IL (US). He has made significant contributions to the field of ink jet printing technology, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of nozzle drive control systems.
Latest Patents
James R. Pickell's latest patents include a "Nozzle drive control system and method for ink jet printing" and an "Ink jet droplet frequency drive control system." Both patents describe a drive control system that automatically maintains nozzle drive voltage within a proper range. The control system monitors the state of the 'intermediate satellites' positioned between ink drops used for printing. When these satellites are neither forward nor backward merging, a first cardinal point designated C(L) is identified. A second cardinal point, C(H), is determined when the drop breakoff point stops decreasing, relative to the nozzle, with increasing nozzle drive voltage. From these two cardinal values, a desired operating range for a particular ink can be computed, and the control system can be automatically set. The computed value is essentially independent of temperature, which enhances the reliability of the printing process.
