The first discharge electrodes may operate as an address electrode, and the second discharge electrodes may operate as a scan electrode. Between the recirculating element and the dust lip, an annular, self-contained sealing bead is arranged which sealingly surrounds the shaft on the peripheral side. Thus, overall system performance is improved, as critical threads execute in a substantially predictable manner.
