Abstract: A coated-core cleaner blade has a core comprising a first material and a coating surrounding the core. The coating comprises a second material that is different than the first material. Further, the core (first material) is rigid compared to the coating (second material). Therefore, the first material has a first flexibility that is much less than a second flexibility of the second material.

Abstract: Method for acoustic dampening of photoreceptor and ionographic drums using an acoustic dampening applied to and cured on the interior of a drum. Embodiments provide excellent acoustic dampening of the resonance modes, and thus, substantially eliminates the problematic sounds that are often emitted from the xerographic printing machines.

Abstract: An interface antenna is positioned between a tag antenna associated with a tag and a reader antenna associated with a reader. The interface antenna receives an electromagnetic carrier signal transmitted by the reader antenna and causes an increase in intensity of the electromagnetic carrier signal at the location of the tag antenna, thereby increasing the distance over which the tag can communicate with the reader. Where the tag is attached to a packaged object, the interface antenna may be included in the package to allow wireless data communication between the tag and a reader external to the package. For example, the interface antenna may be attached to a label on the package. At least a portion of the interface antenna may be formed from a conductive ink applied to the label and/or the container. The object may be a module, also known as a customer replaceable unit (CRU), and the tag may be configured as a customer replaceable unit monitor (CRUM).

Abstract: A xerographic printer or copier includes a replaceable cartridge having a cleaning blade and carrier particle pickoff member associated with a rotating charge receptor. As the cartridge is being used, carrier particles removed from the photoreceptor by the cleaning blade are magnetically retained on the pickoff member, where the remain for the balance of the lifetime of the cartridge. When a useable lifetime of the cartridge is spent, the carrier particles are removed from the pickoff blade.

Abstract: A magnetic brush developer roll structure comprising a stationary magnet assembly including a magnet assembly shaft supporting magnet material. Bearings carried by the shaft, in turn, support a rotatable shell or tube forming the outer member of the roll structure. The bearings together with the shell or tube delineate an essentially sealed cavity in which one or more electrical contact brushes are disposed. The brush rubs against an inner wall of the shell or tube and provides an electrical path thereto. Using a plurality of brushes results in improved reliability.
