A magnetic brush cleaning system for cleaning residual toner from a photoreceptor in a xerographic reproduction machine includes a magnetic brush roll having carrier beads thereon for removing toner from the photoreceptor and a reclaim roll for removing the toner from the magnetic brush roll. As can be seen in the figure, the magnetic brush roll 10 is located adjacent the photoreceptor 12, and the reclaim roll 14 is located adjacent the magnetic brush roll. To obtain optimum packing density of carrier beads and brush compression in the cleaning nip region "Aff, it is necessary that certain parameters be controlled. These parameters include the magnetic field intensity and positioning of stationary magnets 16 and 18 of the magnetic cleaning brush roll, the setting of the gaps t and the brush height of the brush created by the carrier beads (not shown). 1'
