Abstract: The corotron wire of a corotron device is introduced with a retainer element, such as in a printer or copier. At least one corotron wire is held by the retainer element and the carrier material for a latent image residing there opposite is conducted past the corotron wire. The carrier material and the corotron wire lie in planes arranged substantially parallel to one another. The retainer element lies on bearings at at least two bearing points, the bearings being rigidly connected to the guide element and pressed onto the bearings with a spring power. A method is also provided for introducing the corotron wire of a corotron device with assistance of the retainer element.

Abstract: A mechanism and a method for generating a corona discharge by a wire-shaped corona discharge electrode provides that the corona discharge electrode is stretched between two end blocks that respectively contain a space for the acceptance of a respective electrode holder insert. The electrode holder insert has a rotational-symmetrical electrode receptacle element with an axially parallel electrode receptacle channel in the generated surface as well as a further electrode receptacle channel in an end face, the further channel adjoining the axially parallel channel and residing perpendicularly thereon, and also has an annular cap element that, proceeding from the end face containing the further electrode receptacle channel, can be pressed onto the electrode receptacle element with the corona discharge electrode guided in the electrode receptacle channels.
