ALEXANDRIA, Va., April 7 -- United States Patent no. 12,596,320, issued on April 7, was assigned to CANON K.K. (Tokyo).
"Correcting density unevenness in image forming apparatus" was invented by Teruhiko Suzuki (Tokyo).
According to the abstract* released by the U.S. Patent & Trademark Office: "A test image is formed by an image forming unit. A sensor receives light reflected from a test image on an intermediate transfer member passing through a detection position and outputs an output signal based on a reception result of the reflected light. A controller reduces density unevenness of images to be formed in a rotation direction of a photosensitive member based on a correction data, determines a reference output signal used to generate th...
