Title: (EN) Fixing station for an electrophotographic printing or copying apparatus
Abstract: front page image
(EN)

A fixing station of an electrophotographic printing or copying apparatus includes a fixing roller (11) heated via a radiator module (30) and a pressure roller swingable up to and away from the fixing roller (11) via a cam mechanism (8, 7). In order that the fixing roller and pressure roller can be exchanged in the hot state, the fixing roller (11) is mounted in bearing flanges (14, 16), one bearing flange (16) being fastened fixedly and the other bearing flange (14) releasably in the machine. The releasable bearing flange (14) has holding elements (26) for the fixing roller, as well as a handle, by which the bearing flange (14), together with the fixing roller (11) suspended on it, can be removed from the fixing station. The pressure roller (9) is mounted releasably between two rockers (8) via a releasable receiving bolt (57). A cooling sheer (40, 51) is arranged in the machine for receiving the heated fixing roller (11) and the radiator module (30 ).
