An electrostatographic reproduction machine including a cover assembly for holding an original document onto a glass platen, and for dissipating heat build up from the top of the glass platen. The cover assembly includes a heat conductive white film layer for contacting the original document, and a layer of foam with air flow passages therethrough mounted over the white film layer. The cover assembly also includes a rigid frame having a top panel including air flow openings formed therethrough, mounted over the layer of foam, for dissipating heat from the layer of foam and white film layer to the ambient.
