ABSTRACT:
The present invention concerns a thin plate disposed in contact with the surface of a photosensitive drum of a copying machine for guiding toner scraped from the drum surface into a recovery area of the machine; more particularly, it provides for automatic disengagement of the thin plate from its normal contact with the drum surface whenever the drum is not fully engaged within the machine, as during removal and subsequent return for jam clearing or maintenance operations, so as to prevent inadvertent damage to the drum or to the thin plate in the course thereof.
