Patent number: 8615188Abstract: The present teachings provide a fusing method and system of tuning gloss level on a copy substrate. The method includes obtaining an image forming apparatus for forming images on a recording medium including a charge-retentive surface to receive an electrostatic latent image thereon. The method includes applying toner to the charge-retentive surface to develop an electrostatic latent image to form a developed image on the charge-retentive surface. The developed image is transferred from the charge retentive surface to a copy substrate. The toner images are fused to a surface of the copy substrate. The gloss is adjusted on the copy substrate by providing a fuser member having a surface layer a fluoroplastic matrix having dispersed therein aerogel particles wherein the greater a weight percent of the aerogel particles in the fluoroplastic matrix the lower the gloss.Type: GrantFiled: March 22, 2011Date of Patent: December 24, 2013Assignee: Xerox CorporationInventors: Carolyn P. Moorlag, Edward G. Zwartz, Gordon Sisler, Kurt I. Halfyard, Yu Qi, Sandra J. Gardner, T. Brian McAneney, Nan-Xing Hu

Patent number: 8083264Abstract: A document includes a paper substrate having an average surface roughness of at least about 0.5 microns, wherein the paper substrate includes encoded information printed thereon, and wherein the encoded information is printed with an ink comprised of light absorbing material that absorbs light only at wavelengths below 350 nm and an optional clear binder in a solvent. The encoded information is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, and is only revealed upon exposing the document to light having a wavelength at which the light absorbing material absorbs light, which is less than 350 nm.Type: GrantFiled: February 11, 2008Date of Patent: December 27, 2011Assignee: Xerox CorporationInventors: Gabriel Iftime, Peter M.

Patent number: 8073374Abstract: According to aspects of the embodiments there is provided a cassette cleaning web having an agent metering tube that can apply oil via a drip pipe to a web as it enters a nip within the fusing surface. Dispensing the oil as it enters the nip increases the transportation and the holding capacity of the web. The cassette cleaning web can reduce the oil-on-copy to less than 3 mg/copy and more specifically to less than 1 mg/copy which would allow for adequate post finishing applications while still using amino functionalized fuser oil in the fuser subsystem. The cassette cleaning web reduces the contamination of the oil-sump because used web materials are wound up and oil or contaminate materials like wax, toner are retained in the spent web cartridge. This invention enables reduced oil-on-copy, eliminates the bulky and expensive release agent management system, and also provides a direct cleaning to the surface of the fuser roll.Type: GrantFiled: March 1, 2010Date of Patent: December 6, 2011Assignee: Xerox CorporationInventors: Kurt I. Halfyard, T. Brian McAneney, Edward Graham Zwartz

Patent number: 8067142Abstract: Disclosed herein is a xerographic print comprising a substrate having a printed image thereon comprising a low melt temperature toner, and a polyolefin wax coating formed over the printed image having a dry thickness in the range of about 0.5 to about 5 microns. The wax coating substantially prevents toner offset at temperatures up to at least 70° C. A printing system and coating method also are disclosed. The prints, printing system and method are useful for making brochures and books that will be subjected to high temperatures, pressures, and/or humidity levels, such as manuals stored in automobile glove compartments.Type: GrantFiled: December 20, 2007Date of Patent: November 29, 2011Assignee: Xerox CorporationInventors: Kurt I.

Patent number: 8060000Abstract: A method and system for reducing contamination build-up within a fuser roll system are disclosed. The method and system includes a donor roll in rotational combination with a fuser roll. The donor roll can be configured to transfer a toner release agent to the fuser roll to reduce toner build-up on the surface of the fuser roll. A grounded static brush can be located proximate to the donor roll. The grounded static brush can be configured to inductively remove electrostatic discharge from the surface of the donor roll. The reduced electrostatic reduces contamination build-up on the fuser roll, and therefore increases the cycle life of the components of the fuser roll system.Type: GrantFiled: February 9, 2009Date of Patent: November 15, 2011Assignee: Xerox CorporationInventors: Kurt I.
