Abstract: Foil images are formed simultaneously with color toner images on a receiver material. One or more color toner latent images are formed on the receiver material using dry color toners. Each dry color toner has a (a) polymeric resin, a (b) pigment colorant, and a (c) wax that has a melting temperature defined as Tcolor. A foiling latent image is formed using a dry foiling toner that has a (a?) polymeric resin and a (c?) wax that has a melting temperature defined as Tfoiling. The foiling latent image is in an area that is different from the color image areas and Tfoiling is less than Tcolor by at least 15° C. All toners are simultaneously fixed in a fuser oil-free fixing operation. A printing foil can be brought into intimate contact with the fused foiling toner at a foiling temperature (FT) that is greater than Tfoiling but less than Tcolor.

Abstract: Electrophotographic printing of one or more layers of toner using a method of enhancing fuser offset latitude to enable the printing of a wide range of toner mass laydown using electrophotography. This method encompasses the steps of forming multicolor toner images, determining the amount of clear overcoat mass laydown as a function of the color mass laydown or non-raised mass laydown and fusing the clear toner overcoat and the multicolor toner image at a fusing temperature determined by the maximum total mass laydown and the nip width to provide good adhesion to the receiver member while optimizing fuser offset latitude.

Abstract: A electrostatic printer including a fuser configured to heat an receiver to a fusing temperature and a cooling device comprising one or more cooling rollers configured to cool the cooling roller from the fusing temperature to a desired temperature wherein the cooling device is configured to provide a varying rate of heat transfer across the roller so as to create a varying cooling temperature gradient.

Abstract: A precision release agent management system for an electrostatographic reproduction apparatus fuser device. The precision release agent management system includes a reservoir adapted to contain a release agent. A wick absorbs release agent from the reservoir. A metering member receives release agent from the wick, which is supported for resiliently urging into operative contact with the metering member. A blade member is associated with the metering member to establish a desired thickness of release agent on the metering member, and a donor member is adapted to receive release agent from the metering member, and operatively contact the fuser device to apply the release agent thereto. A plurality of features is associated with the reservoir for precise alignment of the donor member, the metering member, and the metering blade.
