Publication number: 20160152055Abstract: A system implementing a method for determining smear tendency of a sheet of print media to reduce smearing on future media sheets of a similar type. The method includes creating an image on the sheet of print media. The sheet of print media is reversed to allow at least one upstream roller to contact and smear the image and create smear marks on the sheet of print media. Reference marks are created over the smear marks and at unsmeared areas of the sheet of print media. To determine the smear tendency, the reference marks over the smear marks are compared to the reference marks at the unsmeared areas. The smear tendency indicates future corrections to an imaging device to reduce smearing on the future media sheets when used by the imaging device.Type: ApplicationFiled: February 8, 2016Publication date: June 2, 2016Inventors: Rebecca Beth SILVESTON-KEITH, John Thomas WRITT

Patent number: 8654414Abstract: An illumination system for a scanner according to one example embodiment includes an array of visible light emitting diodes including a red, a blue and a green light emitting diode and an ultraviolet light emitting device configured to emit light predominantly in the ultraviolet region of the electromagnetic spectrum. During a scan sequence of the red, blue and green light emitting diodes, at least one of the visible light emitting diodes and the ultraviolet light emitting device are positioned to simultaneously illuminate an object being scanned. In one form, during the sequence, the blue light emitting diode and the ultraviolet light emitting device are simultaneously illuminated while in another the red light emitting diode and the ultraviolet light emitting device are simultaneously illuminated.Type: GrantFiled: November 30, 2011Date of Patent: February 18, 2014Assignee: Lexmark International, Inc.Inventors: Yao Han, Richard Lee Reel, Rebecca Beth Silveston-Keith, Steven Frank Weed

Patent number: 8188158Abstract: The invention provides an ink formulation comprising a polymer associated self-dispersed colorant. The polymer has an alkyl amino end functional group that is chemically associated by electron donation/acceptation and hydrogen bonded to surface functional groups of the colorant particles. The modified self-dispersed colorant shows improved printing quality.Type: GrantFiled: July 18, 2008Date of Patent: May 29, 2012Assignee: Lexmark International, Inc.Inventors: Craig Michael Bertelsen, Yaqiang Ming, Rebecca Beth Silveston-Keith, Jing X.

Publication number: 20080044634Abstract: Printed circuits having conductive traces applied adjacent to a substrate, such as one where the traces have a resistivity of from about 1 to about 0.1 ohms/square, and methods for forming a fluid composition receiving layer adjacent to a substrate. One such method includes depositing a primary treatment fluid having a particle dispersion and a binder in a carrier fluid adjacent to at least a portion of a substrate to provide a treated substrate having a fluid composition receiving layer. The primary treatment fluid is deposited in a pattern using a: micro-fluid ejection head. After deposition, the carrier fluid content of the fluid composition receiving layer is reduced.Type: ApplicationFiled: August 7, 2007Publication date: February 21, 2008Applicant: LEXMARK INTERNATIONAL, INC.Inventors: Billie Jo Enciu, Ann P. Holloway, Paul Sacoto, Jean Marie Saldanha Singh, Rebecca Beth Silveston-Keith

Publication number: 20080044631Abstract: Methods for improving adherence of conductive traces, such as in a printed circuit, and circuits having conductive traces formed in accordance with such methods. One such method includes depositing a fluid composition receiving layer adjacent to a substrate, and depositing a gradient layer adjacent to the fluid composition receiving layer. The gradient layer is comprised of a fluid composition providing the fluid composition receiving layer and a fluid composition providing a conductive layer. A conductive layer composition is deposited adjacent to the gradient layer to provide the conductive layer.Type: ApplicationFiled: August 14, 2007Publication date: February 21, 2008Applicant: LEXMARK INTERNATIONAL, INC.Inventors: Paul Sacoto, Jeanne Marie Saldanha Singh, Rebecca Beth Silveston-Keith
