Patent number: 11740568Abstract: In an example of the disclosure, an imaging oil is applied upon a photoconductor surface. An element is brought into contact with the imaging oil at the photoconductor surface. The element has a first refractive index that is within a predefined tolerance of a second refractive index of the imaging oil. The photoconductor surface is exposed to light emitted by a writing component. The light passes through the element and the imaging oil.Type: GrantFiled: September 18, 2018Date of Patent: August 29, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Lavi Cohen, Sasha Zilbershtein, Michael Vinokur, Michael Plotkin
