    摘要： A flexible imaging sheet and a method of constructing a flexible imaging sheet is disclosed. The method of constructing a flexible imaging sheet comprises a step of overlapping, a step of joining, and a step of shaping. In the step of overlapping, a first marginal end region and a second marginal end region of a sheet are overlapped to form an overlap region and a non-overlap region. In the step of joining, the first marginal end region and the second marginal end region of the sheet are joined to one another by a seam in the overlap region. In the step of shaping, the overlap region is shaped to form a generally planar surface co-planar with a surface of the non-overlap region. The flexible imaging sheet comprises a first marginal end region and a second marginal end region The first marginal end region and the second marginal end region are secured by a seam to one another in the overlap region. The first marginal end region and the second marginal end region are substantially co-planar to minimize stress on the flexible imaging sheet. Minimization of stress concentration, resulting from dynamic bending of the flexible imaging sheet during cycling over a roller within an electrophotographic imaging apparatus, is particularly accomplished in the present invention.

    摘要： A belt loading apparatus has been provided for loading a flimsy continuous belt onto a belt support and drive assembly including a vertical front end having a first shape and without damage to the belt. The belt loading apparatus includes a wall member defining a sleeve including an outer surface having a total outer surface area, a first edge and a second and opposite edge. The second edge has a vertical profile having a second shape such that the second shape of the second edge is a mirror image of the first shape of the belt support and drive assembly. The belt loading apparatus then includes friction reducing members formed on the outer surface of the sleeve for temporarily supporting and spacing a flimsy continuous belt to be loaded onto the belt support and drive assembly. The friction reducing members each have a belt contact area such that a sum total of belt contact areas of all the friction reducing members is significantly less than the total outer surface area of the sleeve.

    摘要： The present invention is an apparatus for tuning or altering the charge potential limiting effect that a scorotron grid has upon an adjacent charge receiving surface. The scorotron charging apparatus utilizes corona producing means, spaced above the charge retentive surface, for emitting corona ions in response to a high voltage potential applied thereto, and a flexible grid, suspended between said corona producing means and the charge retentive surface in a nonplanar fashion, such that the spacing between said grid and the charge retentive surface is variable along at least one region of said grid.
