Abstract: Techniques for facilitating communication between a first group communication system and a second group communication system. A naming convention of the first group communication system allows at least one name which contravenes a naming convention of the second group communication system. A communicator is joined to the second group communication system. The communicator was previously joined to the first group communication system and has a first name at the first group communication system. The communicator has a second name at the second group communication system. The second name can be requested from the second group communication system. The second name can also be generated by applying an algorithm to the first name. A processor performs translation between the first name and the second name in a communication between the communicator and the second group communication system. The translation is performed based on a translation data structure.

Abstract: Magnetic carrier particles are removed from a photoconductive image member by subjecting the carrier particles to a magnetic field while or after exposing the photoconductive image member to erasing radiation in the absence of a substantial electrical field affecting the carrier particles.

Abstract: In electrographic apparatus a latent image on a flexible photoconductor is developed with toner particles at a development station and subsequently transferred to a receiver sheet, such as a copy sheet, and then fused to the sheet. Sometimes unwanted particles are on the photoconductor, including the area where an image is to be developed on the photoconductor. These particles are removed by a magnetic brush system located closely adjacent the surface of the photoconductor prior to the charging station. A biased ski located under the photoconductor presents the photoconductor to the cleaning nap at a predetermined uniform pressure and a desired distance, so that the photoconductor is uniformly cleaned and buffed.

Abstract: A scavenging device for recapturing charged carrier particles from a moving image-bearing surface includes a first pickup member and a second pickup member. The first pickup member is mounted adjacent toner and carrier particles on the image-bearing member, and is biased electrically to a polarity relatively opposite to the polarity of the charged carrier particles. The second pickup member is also mounted adjacent toner and carrier particles on the image-bearing member to be effective at a point downstream of the first pickup member. The second member, as such, is electrically grounded for capturing from the image-bearing member wrong sign carrier particles.

Abstract: An image-forming apparatus is adapted to make duplex copies with a separate pass through the fuser for each side. To prevent fusing oil from contaminating an image member by passage from a first image side of a duplex copy to a transfer drum and, hence, to the image member, an oiling algorithm to prevent or lessen oiling during fusing of the first side of duplex copies is provided. Preferably, the apparatus has a finite duplex return path which can hold a limited number of receiving sheets, which number is small enough that offset does not occur while doing first side-duplex fusing.

Abstract: In an electrostatographic machine such as a copier or printer, a cleaning apparatus for removing charged and uncharged particles from the surface of an image-transfer assist member such as an intermediate transfer member. The cleaning apparatus includes a plurality of potential sources for selectively biasing the intermediate transfer member and the image-bearing member of the machine, and a dc corona discharge device for actively charging such particles on the intermediate transfer member for transfer back to the image-bearing member.

Abstract: Magnetic brush development apparatus for applying developer material to a latent electrostatic image in which flow of developer material, distributed in balance across the length of the apparatus, is assured. The apparatus includes a housing having a portion defining a sump adapted to contain a supply of developer material. A magnetic brush is located substantially within the housing in spaced relation to the sump portion for applying developer material to the latent image. A feed mechanism, located within the housing between the sump portion and the magnetic brush transports developer material from the sump to the magnetic brush. An agitating and transporting mechanism, located in said sump portion, agitates developer material and transports developer material to the feed mechanism. In the preferred embodiment the agitating and transporting mechanism is a ribbon blender.
