A system and method for determining a color separation registration error in a multi-color printing system are provided. The system and method provide for instructing first and second color separations to mark a substrate with first and second fine-periodic-patch images to determine color separation registration error(s). The system and method further provide for determining whether at least an about half-period color separation registration error exists between the first and second color separations.

A device prevents the migration of particles from the edge of a moving surface, such as a photoreceptor in an electrophotographic printing apparatus. A brush in contact with an edge of the surface includes fibers of a first type, and fibers of a second type. The fibers of the second type are less resilient than those of the first type and substantially incapable of abrading the surface. The brush guides the particles toward a bead-removal device.
