Abstract:
Digital printer or copier machine (1) with a fixing device (3) for fixing a toner image onto a substrate (5), that is especially made of paper or cardboard and is guided along a transport plane (E) in a direction (17), where the fixing device (3) contains at least one radiation device (7), directing electromagnetic radiation (11) along a radiation path (21) for impinging at least one substrate side (13) with the electromagnetic radiation (11), and with a device (23) for protection against excessive heating of the substrate (5), characterized in that the protection device (23) has at least one stopper (24, 31) arranged fixed in the radiation path (21) between the at least one radiation device (7) and the transport plane (E) of the substrate (5), which prevents a contact between the substrate (5) and the at least one radiation device (7), said at least one stopper (24, 31) is made of at least one mesh structure (25) having only a low heating capacity and/or only low heat conductivity.
