  • Patent number: 8692011
    Abstract: A novel composition for use as a print head face plate coating. In particular, the coating comprises siloxyfluorocarbon (SFC), which is composed of networked precursors containing reactive siloxane groups attached to fluorocarbon chains. The present SFC coatings can be used to produce a surface whereby solid ink and ultraviolet (UV) curable inks do not adhere when applied at elevated temperatures and over an extended period of time. The advantages of the present coating are fewer print head related defects, and longer front face life.

  • Patent number: 8615188
    Abstract: 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.
