摘要： An electrophotographic printing or copying machine has a cooling device (K) for the heated recording medium arranged downstream of the thermofixing device (W) in the direction of transport of the copying medium. The cooling device (K) consists of a cooling saddle through which the cooling medium flows and which has a cooling surface (19) over which the recording medium is guided so as to cover the cooling surface (19). The cooling surface may have air outlets (20) through which air is supplied into a gap between the copying medium (17) and the cooling surface (19) so as to form an air cushion. Additional cooling devices may be provided for further cooling the copying medium by generating a current of cooling air blown over the surface of the copying medium against its direction of transport.

摘要： A thermofixing arrangement for fixing toner images on a strip-shaped recording medium (17) of an electrophotographic printing or copying machine has a thermoprinting fixing station (11, 12) and a heated preheating saddle (15) arranged upstream of the thermoprinting fixing station in the direction of transport of the recording medium. The preheating saddle (15) is designed as a low temperature saddle which is as long as possible, so that the temperature difference between the recording medium (17) and the saddle surface (24) is as reduced as possible. It has several heating zones (21, 23) arranged in the direction of transport of the recording medium. A regulating arrangement regulates the heating zones (21, 23) in such a way that an approximately constant thermal energy flow is set along the preheating saddle (15) at the surface (24) of the saddle on the recording medium (17). In order to adapt the preheating saddle (15) to recording media having different widths, the preheating saddle is subdivided into individually controllable transverse heating zones (30/1 to 30/3) which extend across the direction of transport of the recording medium.

摘要： An electrographic printer or copier contains, for example, a preheating plate (20, 21) upstream of a pair of fixing rollers in the direction of travel of the substrate and a brake unit (10). The preheating plate (20, 21) and the brake unit (10) form a sliding surface (23). Good contact between the sliding surface (23) and the substrate is provided by suction apertures (18, 19) coupled to an underpressure-generating device. A valve (1) may be used to adapt the underpressure to the operating parameters of the printer and copier and those of the substrate.

摘要： An electrophotographic printer or copier with an illumination correcting device for the optical character generator (ZG) contains means, e.g. a filter (FT), to compensate for the wavelength-dependent light sensitivity of the charge image substrate (FL) by controlling the lighting energy of the lighting devices (LED) dependently upon the wavelength of the light emitted by them and the light sensitivity of the charge image substrate (FL). This prevents the formation of undesired colour differences in the form of stripes when colouring large areas.

摘要： Un appareil électrophotographique d'impression ou de copie comportant un dispositif de correction de l'éclairage pour le générateur optique de caractères (ZG) contient des dispositifs tels qu'un filtre (FT) pour compenser la sensibilité lumineuse, en fonction de la longueur d'onde, du porteur d'images électroniques (FL) par la commande de l'énergie d'éclairage des éléments lumineux (LED) en fonction de la longueur d'onde de la lumière qu'ils émettent et de la sensibilité lumineuse du porteur d'images électroniques (FL). On évite ainsi des différences de coloration gênantes sous forme de raies dans la mise en couleur de grandes surfaces.

摘要： When modules (11) are arranged on a module support (13), for example in an optical character generator (1), it is essential that the modules (11) be fastened to the module support (13) by interlocking and frictional engagement, particularly in the event of thermal expansion. To this end, a fastening device (7) is arranged in a borehole (135) obliquely to the contact surface of the module (13) and of the module carrier (13), and the module is thereby detachably fastened to the module carrier (13). The arrangement for detachably fastening modules (11) to a module support (13) is particularly suitable for use in an optical character generator (1) of a non-mechanical printer.

摘要： A non-mechanical printer usually comprises a character generator (1) with a plurality of light sources (113) in the form of chips (112) fastened to the character generator (1). In the event of failure of one light source (113), it is not possible to simply interchange individual chips (112) and the entire character generator (1) must be replaced. The character generator (1) according to the invention is of modular design, i.e. individual modules (11), each with a plurality of light sources (113), are detachably fastened to a module carrier (13) of the character generator (1), so that in the event of failure of individual light sources (113) or other electronic components, individual modules (11) can be simply interchanged. The character generator is particularly suitable for non-mechanical printers, in particular electrophotographic printers.
