Laser printing of continuous forms by means of electrophotographic imaging requires that the paper on which the printing is carried out show good handling characteristics at fast machine speeds and be compatible with toner transfer and fixing. Toner transfer requires suitable electrical paper characteristics, similar to those of xerographic cut sheets intended for use in electrophotographic cut-sheet copiers and printers. Hot-pressure fusing in the IBM 3800 printing subsystem has been shown to require adequate paper-fiber wettability by the hot molten toner. Therefore, characteristics of paper chemistry, and in particular paper sizing, are essential in creating good image fixing (fusing). In addition, the temperature and pressure in the fusing assembly affect the thermal and dimensional stability of the paper. For the 3800, this necessitated modifications in roll design within the fusing station in order to ensure satisfactory paper handling.
