ABSTRACT:
An electrophotographic printer has an electro-thermally operating fixing station (23) with a heated fixing roller (86) and a feed roller (87) which can be pivoted on and away. With the aid of an unheated, pivoting paper guide saddle (93), the reel paper is guided around the fixing roller (86) at a predeterminable wrapping angle (U) for the purpose of preheating before the actual fixing. In order to fix the printed image on the reel paper (12) in an offset-free and smudge-free manner during the starting and stopping process, the movements of the elements of the fixing station (23) and the transport of the paper are coordinated in such a way that there is no relative movement between the fixing roller (86) and toner image on the reel paper (12) when the reel paper is placed against the fixing roller (86) and when the reel paper (12) is stripped off the fixing roller (86). The wrapping angle will change between a standby and an operating position and depending on the temperature of the fixing roller and the transport speed of the paper.
