  • Patent number: 5968704
    Abstract: A transfer support and a method for fusing a transferable toner image to a face of a digital disc. In the method, a transferable toner image is electrophotographically printed onto a transfer layer. The transfer layer has a surface energy insufficient to retain the transferable toner image against a peel force of greater than about 550 Newtons/meter. The transferable image is registered against the face of the digital disc to provide a transfer support-digital disc pair. The transferable image is fused to the face of the digital disc. Registry of the transferable image and the face of the digital disc is maintained during fusing.

  • Patent number: 5659855
    Abstract: An image forming apparatus uses an endless belt image member having a magnetic strip along one or more edges. A linear printhead is flashed in response to a magnetic encoder signal in the magnetic strip. Preferably, the apparatus has first and second linear writers and the magnetic encoding signal is created in the magnetic strip in conjunction with creation of a writing signal for the first writer with the second writer using the magnetic encoding signal to register its writing with the first writing. Preferably, an auxiliary signal is placed in the strip indicative of variable characteristics of either the image member or the image forming apparatus. This in turn is read by the apparatus and a charging, exposing or toning station controlled in response to the auxiliary signal.

  • Patent number: 5035927
    Abstract: A device for fusing and fixing electrophotographic toner powder to a receiver sheet and a method for using the same. The device comprises a first fusing member, such as a fusing roll, having a resilient surface for pressure contact with thermoplastic toner on the receiver sheet. A second member, which can be a non-resilient pressure roll, presses the toner into contact with the resilient surface. The device also is designed to heat the toner. The fusing member has a layer of an elastomeric, amorphous silarylene-siloxane alternating or random copolymer which is thermally stable, has good wear resistance, and good thermal conductivity and exhibits little or no swelling when contacted with poly(dimethylsiloxane) release oils.
