<p>A corotron wire cassette including a supply reel seated therein for the acceptance of a wire-shaped electrode is interchangeably provided in a corona-generating means of an electrophotographic printer or copier device. The supply reel in the corotron wire cassette includes a restoring spring. The wire-shaped electrode is conducted via a deflection roller comprising felt rings secured thereon for cleaning the wire-shaped electrode. Connected to the wire-shaped electrode, a coupling clip is provided at the output of the corotron wire cassette, this coupling clip cooperating, in the inserted condition of the corotron wire cassette, with a holding element of a cleaning slide of the corona-generating means. Via an electro-motive means, a control device automatically pulls the wire-shaped electrode out of the cassette in accord with the preset paper width after the cassette is inserted. When a cleaning procedure is initiated, the cleaning slide is moved back and forth in its guide channel via the electro-motive means.</p> |
