Title: The Innovative Contributions of David W. Holcomb
Introduction
David W. Holcomb is a notable inventor based in Lexington, KY (US). He has made significant contributions to the field of printing technology, particularly through his innovative patent related to printhead design. His work has implications for improving the efficiency and longevity of printheads in various applications.
Latest Patents
David W. Holcomb holds a patent for "Printhead shifting for wear distribution." This invention addresses the wear on the elements of a printhead by spreading the region of use line by line. The technology utilizes font information to determine whether any character in a line employs the upper or lower parts of the print line. The selection logic controls the paper feed to index the platen to the least used position of the printhead. This method ensures that only the electrodes over the print line in each shifted position are used for printing, effectively distributing wear without requiring special ribbon feed. The design also considers the height of the three pels, which is at least as wide as the serifs on most characters, preventing excessive use of electrodes for serifs across different shift positions.
Career Highlights
David W. Holcomb is associated with International Business Machines Corporation (IBM), where he has contributed to advancements in printing technology. His innovative approach to printhead design showcases his commitment to enhancing the functionality and durability of printing devices.
