Title: Innovations by David R. Wyble
Introduction
David R. Wyble is a notable inventor based in Webster, NY (US). He has made significant contributions to the field of digital xerography, particularly in the estimation of toner usage in copiers and printers. With a total of 2 patents, his work has had a considerable impact on the efficiency and effectiveness of printing technologies.
Latest Patents
Wyble's latest patents include a method for estimating toner usage in digital xerographic copiers and an improved method for estimating toner usage in digital xerographic printers and copiers. The improved method is characterized by its consideration of digital image dot spreading, which results in the area of a pixel not being fully developed, along with some areas outside of the pixel being developed. This method compensates for the departure of a developed image from an ideal shape, such as a square. By focusing on pixel groupings rather than simple pixel counting, this innovative approach enhances the accuracy of toner usage estimation.
Another significant patent is the rotating vane toner transport for blade cleaning on horizontal surfaces. This toner removal device effectively removes residual toner and debris from a charge retentive surface after the transfer of toner images. It features an integral extruded multi-vaned toner transport member that vertically removes toner accumulated at a cleaning blade, chiseling toner from the charge retentive surface and transporting it to an augering transport device for disposal.
