ABSTRACT:
In a copying apparatus in which copy sheets are stripped from a reusable imaging surface after the images have been transferred thereto, a vacuum stripping system is provided in which a pivotable, highly apertured, stripping head is normally closely spaced from the imaging surface and connected to a vacuum source to pneumatically capture the lead edge area of the copy sheet. The coverage of the vacuum apertures in the stripping head by the captured sheet pneumatically lifts the stripping head away from the imaging surface into alignment with a copy sheet transport, and shifts the stripping point of the body of the copy upstream on the imaging surface.
