Title: Innovations of Robert Warren Rumford
Introduction
Robert Warren Rumford is a notable inventor based in Lexington, KY (US). He has made significant contributions to the field of printing technology, holding a total of 9 patents. His work primarily focuses on enhancing the efficiency and functionality of inkjet printers.
Latest Patents
Among his latest innovations is the "Star wheel with adjustable directional biaser," which is a print media feed system designed for inkjet printers. This system features a media feed roll, a star wheel mounted opposing the roll, and an adjustable biaser that is coupled to the star wheel. The controller associated with the biaser can vary the magnitude, direction, or both of the biasing force applied to the star wheel. In one embodiment, the biaser includes a motor-driven cam that adjusts the angular position of a pivotable lever with the star wheel attached. Alternatively, a rack and pinion gear assembly can be utilized to modify the biasing force, or a solenoid can be employed to adjust the force applied to the lever or the star wheel.
Another significant patent is the "Method of using star wheel with adjustable directional biaser." This method involves printing with an inkjet printer that includes a printhead and a star wheel located downstream from the printhead. The process entails analyzing print data to identify the area to be printed, calculating the density of the printing in that area, and determining if the density exceeds a certain criterion. If it does, the adjustable biaser lifts the star wheel off the sheet before the printed area reaches it, allowing for a smooth advancement of the printed area past the star wheel.
