His innovative work addresses critical issues in printing processes, particularly concerning the maintenance and efficiency of fuser rollers.

Latest Patents

Fisher's latest patents include a heater roller cleaner and a method and apparatus for a fuser assembly. The fuser roller and heater rollers in fusing systems can become contaminated with ink and other foreign materials when pre-printed materials are processed. This contamination can lead to cold spots, resulting in poor fusing and other image defects. His invention provides a heater roller cleaner that applies an array of differential pressure generating areas to the heater roller surface while it rotates, effectively cleaning it. Additionally, he developed a cleaning brush and method for removing contaminants from a photoconductor film. This cleaning brush features end sections with a reduced coefficient of friction, which helps extend the life of the photoconductor film.
