    摘要: A method of adjusting imaging apparatus including: (a) charging a photoreceptor surface to a first voltage; (b) selectively discharging portions of the charged photoreceptor surface, with a beam of electromagnetic energy such as a laser beam or LED output, having a controllable power, to form a predefined electrostatic latent test image on the photoreceptor surface; (c) developing, using a second voltage different from the first voltage, a layer of charged toner particles onto the selectively discharged portions of the photoreceptor surface, thereby providing a developed test image corresponding to the latent test image; (d) measuring the apparent optical density of portions of the developed test image, including a solid print portion and a predetermined gray level portion; (e) comparing the measured solid and gray level optical densities with predetermined, desired, solid and gray level optical densities; and (f) adjusting the second voltage and the power of the laser beam based on the comparison between the measured and desired solid and gray level optical densities.
