Abstract: A method for forming a receiver transport member for an electrostatographic reproduction apparatus. The transport member transports receiver members with respect to a fuser assembly and is frictional coupled to a transfer member for driving the transfer member. The method for forming the transport member provides a substrate bearing a high friction layer that includes inorganic particles, with a compound of aluminum selected from the group consisting of aluminum hydroxide, alumina hydrate, aluminum oxide, pseudo-boehmite, boehmite alumina, aluminum salts, and mixtures thereof, dispersed in an organic binder so that the high friction layer is capable of preventing a loss of frictional coupling due to release oil applied to a receiver member bearing a fused toner image.

The arrangement provides a low-cost, operator-replaceable cartridge having one or more wiper blades with at least one of them having the dust seal blade assembly and enclosed within a particle sump assembly that is easily removed from association with the web being cleaned.

Abstract: A cleaning station for removing particulate material from a moving web in an electrostatic printer/copier includes a customer-replaceable web-cleaning cartridge and a support bracket/backup shoe assembly. The latter serves to support the cleaning cartridge for movement between an operative position in which web-cleaning components of the cartridge exert a substantially uniform pressure on the web, and a service position in which the cartridge is sufficiently spaced from the web to facilitate replacement and/or service. Preferably, a bracket that supports the cleaning cartridge is pivotally connected to a backup shoe that is fixed with respect to the web path and exerts a uniform pressure on the rear surface of the web, opposite that contacted by the cleaning cartridge. A quick disconnect feature enables the cartridge-supporting bracket to be de-coupled from the back-up shoe and removed from the instrument.

Abstract: An electrostatographic reproduction apparatus having a transfer assembly, including an electrically biased transfer roller in nip relation with a dielectric support member, for effecting transfer of a pigmented marking particle image from an image area of a dielectric support member to a receiver member in transfer relation with the dielectric support member in the transfer nip, a mechanism for cleaning the transfer roller including a control for the electrical bias on the transfer roller. The electrical bias control has a power supply generating an electrical output, of a settable polarity, connected to the transfer roller for applying an electrical bias of a set polarity thereto. A timing signal generator produces signals respectively corresponding to the location of a receiver member relative to the transfer nip.

Abstract: A method and apparatus for cleaning toner and/or other contaminant particles from a moving surface to be cleaned in an electrostatographic apparatus includes a cleaning blade, such as a wiper blade or a scraper blade, that engages the surface to be cleaned at a first location to remove the particles from the surface. A dust seal blade is provided that extends toward the surface in a second direction generally opposite to the first direction, which corresponds to the direction of motion of the surface to be cleaned, and is of a length and supported so as to be able to contact the surface to be cleaned at a second location upstream of the first location. The cleaning blade, the dust seal blade and the surface to be cleaned form a cavity for containing contaminant particles to assist in operation of the cleaning blade apparatus.

Abstract: A mechanism for cleaning the toning roller of a development station for a reproduction apparatus, the toning roller serving to apply marking particles to a latent image to develop such image. The cleaning mechanism comprises including an elongated polyurethane blade having a lead edge. The elongated polyurethane blade is mounted such that the lead edge contacts such toning roller at an angle to a plane tangent to such toning roller, the angle when measured between the plane and the blade adjacent to the cleaned side of the toning roller being in the range of approximately 10.degree.-30.degree..

Abstract: A series of toner images are formed on an endless belt having a splice. The toner images are transferred to a receiving sheet which is fed between the belt and a rotatable transfer member. The transfer member is cleaned by transferring toner back to the belt. Excess toner transfer from the splice of the belt to the transfer roller is obviated by either making the transfer member of a size that the toner will transfer back at an interframe area or applying a lacquer or other similar material to this splice to prevent the pickup of toner initially.

Abstract: First and second toner images are created on a primary image member. The first toner image is transferred to an intermediate image member and then transferred back to the primary image member to combine the two images. Preferably, the intermediate image member is a light roller that is inarticulatable and maintained in contact with the primary image member which is preferably an endless belt with sufficient wrap to drive the intermediate image member with low pressure in the contact nip. Cleaning is effected by transferring residual toner back to an empty portion of the primary image member from where it may be cleaned off by a primary image member cleaning station. Intrack registration of the images is maintained by adjusting the time between flashes in creating the two images.

Abstract: An image forming apparatus includes a nest for receiving a photoconductive drum cartridge. The nest includes an electrometer projecting from an end of the nest parallel to an axis of rotation of a drum in a received cartridge. An opening in a received cartridge housing receives the electrometer closely spaced from the photoconductive drum. The cartridge also includes a charging station and a cleaning station. The cleaning station includes a blade and a roller upstream of the blade for directing cleaned toner toward a containing device opposite the blade from the roller.

Abstract: A mechanism for cleaning an image-bearing surface in an electrostatographic apparatus includes an elongate container for receiving and holding toner and other particles removed from such surface. The container which includes a sump that has a front portion and a rear portion, is liftable from a first and generally horizontal position, to a raised, second and partially upended position on one end. The sump of the container includes slanted flow guides therein for moving toner and other particles from the front portion to the rear portion thereof by lifting the container from the first position to the second position.

Abstract: A rotatable wiper blade roller for cleaning residual toner particles from an image-bearing surface includes a shroud, a plurality of indexable wiper blades that each engage the image-bearing surface at an angle of 60.degree. to 85.degree. defined in the direction of particle removal by the cleaning edge of each such blade and the image-bearing surface, that are each cleaned secondarily by an intermittently rotatable fur brush that is completely out of contact with the image-bearing surface.

Abstract: A cleaning blade for precise loading and sealing against an electrostatographic surface to be cleaned has a stiffness per unit length value within the range of 0.5 lb./in..sup.2, and a thickness T tolerance of .+-.4% T.

Abstract: The inner diameter of a single and compact external dusthood that houses the fiber brush of a brush-vacuum cleaning apparatus, is made to be substantially less than the average outer diameter of such fiber brush, thereby creating a substantial interference fit of the brush with the inside of such an external dusthood. The substantial interference contact between the brush and the inside of the external dusthood is such that any open or free air passage ways or air pockets between the brush and the external dusthood are eliminated, and such that toner particles removed by the brush from an image bearing surface are immediately entrained and carried (through the external dusthood) against the inside wall of such external dusthood, thereby preventing such particles from ever becoming airborne, or building up anywhere within the external dusthood.
