  • Fuser system for controlling static discharge
    Patent number: 9069307
    Abstract: The present teachings provide a fuser system for use in a xerographic apparatus. The fuser system includes a fuser roller and a pressure roller. The fuser roller and the pressure roller create a nip. The fuser roller has an outer layer of carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the outer layer. The pressure roller comprises a static dissipative outer surface having a surface resistivity of less than about 1010 ?/cm.
    Type: Grant

  • Signature booklet maker with a modified fold blade and a trim waste elimination device
    Patent number: 5377569
    Abstract: A signature booklet maker (SBM) finishing apparatus for an image producing device includes a modified fold blade having a plurality of contacting teeth spaced part by a predetermined distance. The contacting teeth further include a predetermined contact surface width and a predetermined thickness. The grind direction of the teeth is specified to reduce inside sheet drag during folding. The spaced teeth are adapted drive the stitched signature set in a folding unit without contacting the stitches, thereby eliminating fold skew and inside sheet marking. Moreover, the fold blade has a predetermined hardness to ensure that the blade is not damaged during folding. The SBM further includes a trim waste elimination device and knife guard to prevent booklet trimmings from migrating throughout the trimmer unit. The knife guard eliminates the safety hazard caused by the blade in the resting position and guides air from an air blower to force booklet trimmings into a waste chute.
