ABSTRACT:
To suppress spread of fire from a fixing chamber of a fixing station in an electrophotographic print or copy device, in the event of a fire, in order to partition a fixing chamber for a recording medium in a fireproof manner, arranged at the openings of the fixing chamber is a safety apparatus made of an elastic sealing element and a counter-element, between which the recording medium is guided through. The sealing element is comprised of a fiberglass tube, inside which an elastic filling material or an elastic spreading element is situated. When the sealing element is pressed on the counter-element, a clamp region for the recording medium is formed, via which the opening of the fixing chamber can be sealed and a burning segment of the recording medium can be extinguished. Additionally, ashes present on the recording medium can be removed.
