Latest Patents

Among Sadwick’s latest patents is the "Carrier Web Transfer Device and Method for Electrophotographic Printing." This invention presents a transfer mechanism that facilitates the transfer of images from an electrophotoconductive cylinder to a continuous web of paper traveling synchronously with the cylinder's surface speed. The exceptional design includes a transfer corona that effectively attracts over 95% of the solids, specifically toner particles, from the cylinder to the web by focusing a narrow band of ions at the cylinder-web interface. The charging system ensures that the corona charge exceeds the image charge on the rotating cylinder by at least 5,000 volts, thereby enhancing the transfer process.

Another notable patent is the "Corona Charge System and Apparatus for Electrophotographic Printing Press." This invention integrates an electrometer positioned adjacent to the drum surface to measure the charge imparted to the photoconductive surface of a rapidly rotating drum. With a connection to a programmable logic controller, the electrometer enables real-time adjustments to the charge applied by the corona array, ensuring uniformity in charge potential and optimizing print quality.
