Heat transfer apparatus and methods

摘要

An intermediate transfer member (12) defines a transfer nip with a transfuse member (50). A cooling platen (270) contacts the intermediate transfer member (12) in the post-transfer nip region. The cooling platen (268) absorbs heat from the intermediate transfer member (12) to evaporate a liquid into a vapour. The vapour is directed to a heating platen (270) contacting the pre-nip region of the intermediate transfer member (12). The heating platen condenses the vapour to a liquid to heat the intermediate transfer member (270).
