Abstract
A digital printer or copier machine (1) and a device (23) for protection against excessive heating of an object (5, 49), for example, a paper to be printed, that is guided past a radiation device (7) within a digital printer or copier machine (1). The protection device (23) has two protection elements (41, 43) permeable to radiation and arranged at a distance from each other, which are arranged in the radiation path (21) between a radiation device (7) and the object to be heated (5, 49).
Claims25
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 path (17), where the fixing device contains at least one radiation device (7), for impinging at least one substrate side (13) with 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 radiation device (7) and the transport path of the substrate (5), which prevents a contact between the substrate (5) and the radiation device (7).
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 path (17), where the fixing device contains at least one radiation device (7), for impinging at least one substrate side (13) with 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 two radiation permeable protection elements (41, 43) arranged at a distance from each other in the radiation path (21) between the radiation device (7) and the transport path of the substrate (5).
Device (23), especially for a digital printer or copier machine (1), for protection against excessive heating of an object (5, 49) that is guided past a radiation device (7), characterized in that the protection device (23) has at least two protection elements (41, 43) arranged at a distance from each other and permeable to radiation, which are arranged in the radiation path (21) between the radiation device (7) and the object to be heated (5, 49).
Protection device according to claim 25, characterized in that the object is an image carrying substrate (5), and a cylinder or roller (49) that can be heated by the radiation device (7) and acts together with the substrate (5) for fixing a toner image that has been transferred onto it, or is a conveyor belt.
