Fixing belts, fixing devices and methods of making fixing belts are provided. An exemplary embodiment of the fixing belts includes an inner layer comprising a first surface forming an inner surface of the fixing belt and a second surface opposite to the first surface, the inner layer comprising a first polymer; an intermediate layer overlying the second surface of the inner layer, the intermediate layer including a third surface, a first end face and a second end face opposite to the first end face, the intermediate layer comprising silicone rubber; and an outer layer including a fourth surface forming an outer surface of the fixing belt, the outer layer overlying the third surface, the first end face, the second end face and portions of the second surface disposed outward from the first end face and second end face, the outer layer comprising a second polymer. The outer layer seals and protects the intermediate layer from exposure to a liquid release agent applied to the fourth surface.

An apparatus and method that control pressure roll flare in a print apparatus. The apparatus can include a fuser having a fuser surface. The apparatus can include at least one heat source configured to heat the fuser surface. The apparatus can include a pressure roll having a pressure roll surface, the pressure roll having a rotational axis, the pressure roll having an inside paper path portion towards the middle of the pressure roll along the rotational axis and having an outside paper path portion near at least one end of the pressure roll along the rotational axis, the pressure roll coupled to the fuser at a fuser nip, where the fuser nip is configured to fuse marking material on a media sheet. The apparatus can include a pressure roll cooling device configured to cool at least one of the inside paper path portion and the outside paper path portion of the pressure roll to maintain substantially consistent pressure roll flare prior to media sheets entering the fuser nip and while media sheets pass through the fuser nip to provide wrinkle control of media sheets while limiting image smear of the marking material on the media sheets.

An apparatus (100) and method (400, 500) that controls the rate of movement of a fusing belt in a printing apparatus is disclosed. The apparatus can include a fusing belt (120) and at least one fusing belt support roller (131), where the fusing belt can be entrained on the fusing belt support roller. The fusing belt support roller can have an axis of rotation (135). The apparatus can include a pressure roller (132) that contacts the fusing belt to form a fusing nip (137). The pressure roller and the fusing belt can be configured to fuse an image on a media sheet (112) in the fusing nip. The apparatus can include a belt position changing mechanism (150) coupled to the fusing belt. The belt position changing mechanism can be configured to move the fusing belt axially relative to the fusing belt support roller axis of rotation. The apparatus can include a belt position changing control module (152) coupled to the belt position changing mechanism. The belt position changing control module can be configured to adaptively control a rate of the axial movement of the fusing belt.

An apparatus (100) and method (500) that controls the change of direction of a fusing belt in a printing apparatus is disclosed. The apparatus can include a fusing belt (120) configured to rotate about an axis of rotation (128). The apparatus can include at least one fusing belt support roller (131) where the fusing belt can be entrained on the fusing belt support roller. The apparatus can include a pressure roller (132) that contacts the fusing belt to form a fusing nip (137), where the pressure roller, the heater, and the fusing belt can be configured to fuse an image on a media sheet (112) in the fusing nip. The apparatus can include a belt position changing mechanism (150) configured to move the fusing belt axially in a first direction and in a second direction opposite the first direction relative the axis of rotation. The apparatus can include a belt position changing control module (152) coupled to the belt position changing mechanism. The belt position changing control module can be configured to change an axial location of a change in direction from the first direction to the second direction so the fusing belt changes direction from the first direction to the second direction at different axial locations.
