Abstract: A solvent vapor fixing method is provided. Novel dry toner formulations for use with the method are also provided. The method and system of the invention may be advantageously utilized in color imaging, security document imaging, and magnetic ink character recognition printing within electrophotographic, electrographic, and magnetographic imaging systems designed for solvent vapor fixing.

Abstract: A method for cold fusion printing of characters. The method employs a hydrochlorofluorocarbon fusing agent within a cold fusion printing process to provide superior characteristics. Prior to fusion, toner is temporarily held to the surface of paper by the difference in electrostatic charge between the toner and the paper. Vapors of the hydrochlorofluorocarbon fusing agent are directed to the toner and act on the toner so as to permanently affix the toner to the paper, more rapidly than in known hot fusion methods and with fewer adverse environmental consequences than result from known cold fusion methods.
