Abstract:
A method for optimizing a charge image generation on a photoconductor of an electrophotographic printer or copier device, comprising the steps of:a) charging the photoconductor to a predetermined charging potential;b) illuminating the charged photoconductor with a predetermined illumination energy so that the photoconductor is thereby discharged;c) determining a discharge potential of the illuminated photoconductor;d) determining a temperature of the photoconductor;e) determining a sensitivity factor from the charging potential, the illumination energy, the discharge potential and the temperature, said sensitivity factor defining the relationship between the discharge potential and the illumination energy in a predetermined relationship between the discharge potential and the illumination energy given a fixed temperature;f) determining a new illumination energy that is employed instead of a previous illumination energy from the charging potential, the temperature, the identified sensitivity factor and a predetermined rated value for the discharge potential according to the given relationship converted to the illumination energy;g) and generating a charge image with the determined illumination energy and the predetermined charging potential.
