  • Patent number: 4089683
    Abstract: An improved apparatus and method for the conditioning of reusable imaging surfaces after the liquid development thereon of a charge pattern and the transfer therefrom of the developed image to eliminate subsequent transfer of residual liquid developer from the imaging surface cleaned by conventional methods, is described. The imaging surface is prepared for a subsequent cycle by bringing the imaging surface into moving contact with the advancing, transversely-oriented foam belt having a pattern of raised and depressed areas redistributing streaks and deposits of liquid developer remaining on an imaging surface after bringing the imaging surface into moving contact with conventional cleaning means.
    Type: Grant

  • Patent number: 4072307
    Abstract: A sheet stripper for mechanically stripping copy sheets from the moving imaging surface of an edge registration type copier without contacting the actual imaging area of the imaging surface. The stripper has a bearing portion continuously riding only on an edge area of the imaging surface outside of the imaging area. An integral stripping finger is rigidly cantilevered from this bearing portion out over the imaging area into the path of one corner of the lead edge of copy sheets thereon. The stripping edge of this stripping finger is continuously maintained spaced above the imaging area, by less than the thickness of a single sheet, by the adjacent integral bearing portion riding on the closely adjacent area of the imaging surface.

    Abstract: An improved apparatus and method for the conditioning of reusable imaging surfaces after the liquid development thereon of a charge pattern and the transfer therefrom of the developed image to eliminate subsequent transfer of residual liquid developer from the imaging surface cleaned by conventional methods, is described. The imaging surface is prepared for a subsequent cycle by bringing the imaging surface into moving contact with a stationary, compressible pad having a pattern of raised and depressed areas redistributing streaks and deposits of liquid developer remaining on an imaging surface after bringing the imaging surface into moving contact with conventional cleaning means.
