Title: Don W Stafford: Innovator in Toner Technology
Introduction
Don W Stafford is a notable inventor based in Lexington, KY (US). He has made significant contributions to the field of printing technology, particularly in the area of toner cartridge authenticity and transfer mechanisms. With a total of 7 patents to his name, Stafford's work has had a lasting impact on the industry.
Latest Patents
One of Stafford's latest patents is a system and method for determining toner cartridge authenticity via toner patterns. This innovative system includes an electrostatic process unit with a photoconductive drum that generates a toner pattern based on electronic data from the toner cartridge. A transfer belt receives this toner pattern, and a sensor detects it on the transfer belt. The processor then compares the generated toner pattern with the sensed toner pattern, generating an error condition if they do not match. This technology incorporates infrared reflective or ultraviolet fluorescing additives to enhance the detection process.
Another significant patent by Stafford involves transfer belt platens. This system is designed to improve the printing process by transferring toner from a photoconductive drum to paper. The transfer platen positions the transfer belt in proximity to the photoconductive drum, ensuring efficient toner transfer. For color printing, each color of toner has a corresponding transfer platen, which is shaped to optimize the transfer process. The design includes electrically conductive foam and a low-friction conductive top layer, enhancing the overall efficiency of the printing system.
