Abstract: A controlled fuser assembly for a reproduction apparatus. The fuser assembly includes a fuser member for fusing a marking particle image to a receiver member and a cooling system for controlling the temperature of the fuser system. Optional external heater rollers have a heat transfer surface adapted to be selectively engaged with the fuser member, and a device for heating said heat transfer surfaces. A mechanism is provided for controlling the heat transfer with the fuser member to selectively change the amount of heat transferred from the fuser.

Abstract: A printing system includes one or more printing system components positioned opposite a moving print media. A wick assembly can be attached to a printing system component to wick condensation away from a surface of the printing system component that is opposite the moving print media. A heating element can be in contact with one or both of the wick assembly and a printing system component. A protective layer can be attached to the surface of a printing system component that is opposite the moving print media to prevent condensation from forming on the component. A vacuum assembly can be positioned opposite the moving print media to produce suction over the print media that pushes humid air or some condensation into the vacuum assembly.

Abstract: Often times the glossing process results in an image artifact consisting of locally lighter image a fixed distance from the lead edge as a print is glossed. This artifact is most visible in areas of medium but consistent image. The present invention provides methods for reducing this artifact.
