A hollow cylindrical electrostatographic imaging member supporting end flange including a disk shaped member, a supporting hub extending axially from the disk shaped member and a metal disk coaxially secured to the hub, the disk comprising a plurality of rectangular tabs extending radially from the disk in a direction away from an imaginary axis of the hub for engagement with the hollow cylindrical electrostatographic imaging member upon insertion of the hub and disk shaped member into one end of the hollow cylindrical electrostatographic imaging member. When this end flange is inserted into one end of the hollow cylindrical electrostatographic imaging member, the plurality of rectangular tabs extending radially from the disk engage the inner surface of the hollow cylindrical electrostatographic imaging member.
摘要:
A reusable photoreceptor assembly has a gear assembly removable from a photoreceptor. A square leaf spring or ring is used to secure and remove the gear assembly to and from the photoreceptor, thereby avoiding damage to both the gear assembly and photoreceptor during the removal of the gear assembly. The undamaged gear assembly and photoreceptor may then be reused.

A hollow cylinder supporting end flange is disclosed comprising a disk shaped member, a supporting hub extending axially from the disk shaped member and an annular ring supported on the hub, the ring comprising a plurality of sharp protrusions or barbs extending from the ring in a direction away from the hub for engagement with the hollow cylindrical member upon insertion of the annular ring into the hollow cylindrical member. This end flange is utilized in an assembly comprising a hollow cylindrical member having a circular cross section and an inner surface and an end flange comprising a disk shaped member having a circular periphery, a supporting hub extending axially from the disk shaped member into one end of the hollow cylindrical member and an annular ring supported on and secured to the hub, the ring comprising a plurality of sharp protrusions extending from the ring in a direction away from the hub into engagement with inner surface of the hollow cylindrical member to secure the hollow cylindrical member to the end flange.
摘要:
Multiple-seam electrostatographic imaging member belts include two or more imaging member portions joined together by two or more seams. The belts can be formed from imaging member web that either includes or does not include an anti-curl backing layer, and that includes a charge transport layer that is substantially stress free.
摘要:
A method and apparatus are disclosed for capturing coating debris during laser ablation of a photoreceptor comprising: (a) enclosing a predetermined length of a coated substrate in a housing to result in an enclosed coated substrate portion, wherein there exists a gap between the enclosed substrate portion and the housing in communication with air outside the housing; (b) directing high energy radiation at the coating of the enclosed substrate portion; (c) directing a first fluid stream against the coating of the enclosed substrate portion to remove at least part of the coating in the form of coating debris during or subsequent to (b), whereby the first fluid stream may move a portion of the coating debris outside the housing in the absence of (d); (d) directing an annularly-shaped second fluid stream against the first fluid stream in a direction effective for keeping the coating debris inside the housing, thereby minimizing movement of the coating debris into the air outside the housing; and (e) exhausting the coating debris.
摘要:
A method for applying a coating solution onto a substrate to form a coated portion thereon includes a dipping device for dipping and removing the substrate into and from the coating solution; and a heating device for inductively heating the substrate while the dipping device removes the substrate from the coating solution to uniformly dry an inner surface of the coated portion, the inner surface being adjacent to the substrate. The method advantageously may include a drying device for blowing hot gases onto the coated portion of the substrate while the dipping device removes the substrate from the coating solution. The drying device for blowing hot gases onto the coated portion of the substrate includes a plurality of slits arranged so that a plurality of hot gas streams flowing through corresponding ones of the plurality of slits impinge and exert a gas pressure on the coated portion, the plurality of slits being arranged so that a collective gas pressure from all hot gas streams is uniformly applied across the coated portion along a transverse direction so that the coated portion is squeezed to a uniform thickness as the dipping device removes the substrate.
