Abstract
A method for operating an electrographic printer or copier includes determining an adapted exposure energy before the start of the printing process. To this end, a portion of the image elements on a charged photoconductor region is exposed to a predetermined exposure energy. The other portion of the image elements on the photoconductor region is not exposed. A raster parameter which takes the ratio between exposed and unexposed image elements into account is used during the determination of the adapted exposure energy. A printer or copier apparatus for carrying out the method is also provided.
