Title: Carmen J Sofia: Innovator in Electrophotographic Technology
Introduction
Carmen J Sofia is a notable inventor based in Rochester, NY (US). She has made significant contributions to the field of electrophotographic printing technology. With a total of 2 patents, her work has advanced the efficiency and functionality of printing machines.
Latest Patents
One of her latest patents is the "Photoreceptor Drive Module." This innovative drive module is designed for a photoreceptor in an electrophotographic printing machine. It features retractable components that facilitate the insertion and removal of the xerographic CRU without damaging the photoreceptor or other critical subsystems. The module includes various locating members to maintain critical tolerances, and a single handle assembly that retracts, unlocks, extends, and locks the drive module into an operative position. Additionally, it has electrical and drive connections for the cleaning system, charging system, and transfer/detack.
Another significant patent is the "Method and Apparatus for Waste Toner Determination." This invention provides a method to track toner waste and monitor the level of waste toner in a receptacle. A sensor measures the toner developed on a photoreceptive member, sending signals to a machine controller at regular intervals. The controller converts the developed toner amount into a residual waste amount based on machine transfer efficiency. As the toner waste receptacle approaches capacity, a signal is generated for the user, and an end-of-life signal is triggered when full capacity is reached, shutting down the machine until the waste container is replaced.
