摘要：A system and method to compensate for ghost appearances on a print due to a previous job, the method comprising defining areas in which ghosting is expected or detected and recording the image on a photoreceptor by selectively changing the parameters of the system as a function of position, to compensate for the effects of ghosting in ex-image and ex-nonimage areas.

主权项：1. A method of operating a printing system, the method comprising: defining areas on a photoreceptor in which ghosting is expected; recording an image on the photoreceptor by applying a laser to the photoreceptor; and; applying a higher power to the laser when the laser is applied to the areas on the photoreceptor in which ghosting is expected than when the laser is applied to areas on the photoreceptor in which ghosting is not expected.
