An air suction manifold device for removal of fibers/debris from the photoreceptor surface, which may otherwise attach to the development electrode wires causing a print defect(s). The device incorporating a secondary channel perpendicular to the main channel, formed by the manifold flange(s) proximity to the photoreceptor surface. The secondary channel supplying a specific volume of air at a specific mean velocity in a direction perpendicular to the flow direction of the main channel. The volume and velocity of secondary channel air being of such magnitude that it crosses the main channel gap and impinges on the photoreceptor surface, causing a zone of maximum shear stress prior to completely mixing with the main channel air. The maximum sheer stress zone resulting in improved fiber/debris removal performance from the photoreceptor surface.
