Title: **James E. Hogle: Innovator in Inkjet Technology**

Introduction

James E. Hogle, an accomplished inventor based in Williamson, NY, has made significant contributions to the field of printing technology. With two patents to his name, Hogle's innovations have helped advance inkjet systems, particularly in ensuring reliable print quality and operational efficiency.

Latest Patents

One of Hogle's notable patents is for an "Ink jet printhead having out-of-ink detection using temperature monitoring system." This invention pertains to a thermal inkjet printhead equipped with a temperature sensor that monitors its operating temperature. The system stores a maximum allowable printhead operating temperature in the printer's memory. If the sensor detects a temperature exceeding this threshold during printing, it generates a signal indicating that the printhead has stopped ejecting ink droplets, prompting necessary checks for a potential ink supply issue.

His second patent, titled "Transfer apparatus," describes a device designed to transfer developed images from a photoconductive surface to a copy sheet. It features a corona generating device that charges the copy sheet to create a transfer field, which effectively attracts the image from the photoconductive surface. This apparatus includes a specially designed sheet guide that maintains the copy sheet wrinkle-free as it moves into contact with the photoconductive surface.
