1. An image diagnostic system for an electrophotographic engine, comprising: a photoreceptor with a photoreceptor surface; a raster scanning system including at least one light source that illuminates the photoreceptor surface with light with corresponding pixel clock for monitoring spatial information such that light energy is transmitted from the photoreceptor surface; at least one image sensor that receives the light energy transmitted from the photoreceptor surface and transforms the light energy into a corresponding spatial image map of the photoreceptor surface; an image processing system that evaluates the spatial image map of the photoreceptor surface and determines whether an image defect is present.
