ABSTRACT:
Apparatus is disclosed for guiding and cooling a heated image-carrying support moved along a path such as a heated copy sheet exiting from a fuser in electrographic apparatus. The apparatus includes a heat-conductive guide member having a guide surface located adjacent to the path along which the support is moved, and a surface remote from the path. The guide member has a vacuum opening at said guide surface. Heat-dissipating structure thermally communicates with the remote surface of the guide member. The apparatus produces a cooling flow of fluid past the guide member and the heat-dissipating structure. A vacuum is established at the vacuum opening independently of the flow of fluid past the guide member to draw a heated support into contact with the guide surface as it is moved along the path. The support is cooled as it transfers heat to the guide member and then to the heat-dissipating structure.
