Latest Patents
Stan Dorr holds a patent for a method of varying an electric field during the development of a latent electrostatic charge image. This patent focuses on the separation between two plates or electrodes, which is adjusted in proportion to the detected concentration of toner within the developer solution. This control mechanism ensures that the thickness and density of the applied toner film remain constant, thereby maintaining high-quality images even as toner is depleted. The sensing of toner concentration is achieved through electrical resistance, and the control circuit includes an analog-digital converter, a microprocessor, a stepper motor driver/controller, and a stepper motor that rotates a cam to vary the separation between the plates. This innovation extends the useful life of the developer solution for imaging by a factor of at least two.
