METHOD AND DEVICE FOR PRODUCING A CHARGE IMAGE BY ILLUMINATION LINES WHOSE DEVIATIONS FROM A TARGET LINE ARE MINIMISED

A method or system is provided for producing a charge image on an intermediate carrier of an electrophotographic printer or copier. A character generator having a plurality of light sources arranged in at least one row in groups is provided. A separate functional unit is provided for each light source group for control of the light sources. The functional unit is connected with a central control unit, the functional unit comprising an address system via which it can be activated, and a control unit. The light sources of each group are controlled by said control unit assigned to the functional unit. The at least one row of light sources is imaged onto the intermediate carrier as an exposure line, the intermediate carrier being displaced substantially transverse to the exposure line relative to the character generator. A temporal beginning of illumination phases of groups of light sources is selected such that deviations of the exposure line from a target line is reduced.
