  • Publication number: 20110018192
    Abstract: System and methods for directing sheet media to one of multiple output paths is described. A multi-path gating system includes a multi-positionable gate including a fixed pivotable input end for receiving sheet media and a movable output end for routing the sheet media to one of multiple output paths. The multi-path gating system also includes an actuator configured to control the position of the output end of the multi-positionable gate, wherein the actuator orients the output end of the gate forming an output path for the sheet media.

  • Publication number: 20060228639
    Abstract: Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.
