Title: Innovations by Brendan W Kunzmann

Introduction

Brendan W Kunzmann is a notable inventor based in Rochester, NY, who has made significant contributions to the field of electrostatic printing technology. With a total of six patents to his name, Kunzmann has focused on enhancing the performance and efficiency of fuser rolls in printing systems.

Latest Patents

Among his latest patents is a system for charge control for fuser rolls, which aims to prevent print history-related marks on copies. This innovative approach involves controlling the magnitude and polarity of the voltage on the fuser roll surface, either through electronic charge application means or by using charge control agents. For instance, when using negative toner, the fuser roll voltage must also be negative to repel the toner at the entrance to the fuser nip, thereby preventing unwanted transfer and the formation of marks.

Another significant patent is a system designed to minimize print history on a fuser roll. This system utilizes a cleaning web in the electrostatic printing process to apply a uniform and thin wax layer on the fuser roll. By impregnating the cleaning web with a wax material similar to that used in the toner, the system ensures that the wax has the same release and triboelectric properties, effectively repelling residual toner.
