Patent ID: 8078091

Claim:
An apparatus comprising: a first fuser member rotationally supported in the apparatus, the first fuser member configured to fuse an image on a media sheet; a second fuser member rotationally supported in the apparatus and coupled to the first fuser member at a fuser nip, the second fuser member configured to fuse an image on the media sheet; and a rotatable cam mechanism rotationally supported in the apparatus, the rotatable cam mechanism coupled to the second fuser member, the rotatable cam mechanism configured to provide variable pressure between the first fuser member and the second fuser member, the rotatable cam mechanism including: a cam rotational axis; a first cam end at one end of the cam rotational axis, the first cam end including a first cam member having a first cam profile perpendicular to the cam rotational axis; and a second cam end at another end of the cam rotational axis, the second cam end including a second cam member having a second cam profile perpendicular to the cam rotational axis, the second cam profile different from the first cam profile, wherein a portion of the first cam profile is configured to provide constant pressure between the first fuser member and the second fuser member at one fuser member end, and wherein a portion of the second cam profile corresponds to the portion of the first cam profile and the portion of the second cam profile is configured to provide variable pressure between the first fuser member and the second fuser member at another fuser member end while the portion of the first cam profile provides constant pressure between the first fuser member and the second fuser member at the one fuser member end.
