Abstract
A system and method are provided to implement a double belt roll fuser geometry to enable consistent self-stripping of image receiving media exiting a fuser assembly in an image forming device. Interaction between an image receiving medium substrate and a fuser belt of a belt roll fuser device is modified to include configuration in which an opposing belt is positioned around a pressure roller to oppose the fuser belt provided around the fuser roller. The fuser belt and the opposing belt extend in a downstream direction from the fusing nip and are configured to provide an appropriate length downstream of the fusing nip that sandwiches the image receiving medium substrate between the fuser belt and the opposing belt. Each of the fuser belt and the opposing belt wrap 70 degrees or more around significantly smaller diameter rollers positioned downstream of the fusing nip to form a stripping nip.
