Canon Issues New U.S. Patent For Improved Toner Mixture
Canon patent activity focuses on digital cameras and related technologies
Tonernews just Found a couple of patents that extend Canon’s holdings in the area of printing technologies, both for printer units and inks. A self-cleaning style of printer is at the center of the recently issued U.S. Patent No. 8909113, titled Printing Apparatus that Cleans Fixing Device, Method of Controlling the Printing Apparatus, and Storage Medium. The printing apparatus that includes a device for fixing an image on a sheet claimed here includes a unit that performs multiple cleaning processes to clean the fixing device by using a sheet upon which an image is formed having different numbers of color of recording material. The apparatus also includes a determination unit that initiates performance of the cleaning process based on a number of sheets printed. This innovation is an improved system for cleaning toner from a pressure roller within a printing apparatus.

An improved toner mixture for providing magenta color with better color quality characteristics is described within U.S. Patent No. 8906587, which is titled Colored Resin Powder and Toner Using the Colored Resin Powder. The colored resin powder claimed here includes a water-insoluble coloring matter compound composed of a general formula included in the patent as well as a binder resin. The magenta toner of this invention achieves improved color saturation, tone and electrophotographic characteristics, remaining faithful to an original image while providing enhanced transparency.
