A method of making a slotted scavenger wherein a rigid sheet is used as a starting material. A slot is formed through the sheet having horizontally angled sidewalls such that an opening of the slot on a first major surface of the sheet is smaller than an opening of the slot in a second major surface of the sheet. Modifications of the method include using a rotating cutting tool for cutting through the sheet to form slots.

Fabrication on of an alternate scavenger geometry

A printer having a developer station for holding a supply of developer which includes magnetized carrier particles, a magnetized development roller, and an imaging roller proximate the development roller which collects carrier particles during operation of the printer. A scavenger proximate the imaging roller and the development roller removes the carrier particles from the imaging roller during operation of the printer which are then urged through a slot in the scavenger by the magnetized development roller.

A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. A quick disconnect feature enables the cleaner cover to be de-coupled from the cleaner body to allow the debris to be easily removed with replacing the web-cleaner. The cleaner has a cleaner sump that is spring loaded to force contact of four strategically placed stops in the sump with a stationary back up shoe assembly allowing for higher precision of blade engagement with a transport web or a photoconductor. The web-cleaner has two wiper blades that are locked into the cleaner sump by springs, to facilitate dumping of material removed from the web without removing the cleaning blades. The sump has baffles molded into the sump to eliminate extra parts and has several features that enable easy attachment of the cleaning blades, a permanently attached foam seal around the perimeter of the cover and sump interface. The wiper cleaning blades and the cover assembly are easily replaceable by the operator.

A double-sleeved roller (DSR) including: a mandrel having a disconnectable end incorporating three termination plates having specified axial profiles; a replaceable inner sleeve member (ISM) mounted on the mandrel; and, a replaceable multilayer outer sleeve member (OSM) including at least one synthetic layer with the OSM surrounding the ISM. The mandrel, adapted to support a non-reinforced ISM, includes the termination plates joined together so as to define two sets of channels for selectively conveying pressurized air to either OSM or ISM for radial expansion thereof. The termination plates have specialized outer shapes, with each termination end plate including a cylindrical portion adjoining a tapered portion. For removal and/or replacement of the OSM or the ISM, a removable support member is moved away from the disconnectable end of the roller while the other end of the roller continues to be supported in cantilever fashion.

A photoconductive sleeved primary image-forming member roller for use in an electrophotographic machine comprising a central member including a rigid cylindrical core member and a compliant layer formed on the core member; and a flexible replaceable removable photoconductive sleeve member in the form of an endless tubular belt that surrounds and non-adhesively intimately contacts the central member.

Sleeved photoconductive member and method of making

An intermediate transfer member (IT) roller for use in an electrostatographic recording apparatus comprising a core member; a compliant layer covering the core member; and a stiffening layer covering the compliant layer, wherein the stiffening layer includes an endless belt that has a thickness in the range of greater than 50 and up to 1000 micrometers.

Intermediate transfer member having a stiffening layer and method of using

In accordance with the invention, there is provided a reproduction method including forming a toner image on a moving primary image-forming member (PIFM) which is a first double-sleeved roller including a rigid cylindrical core member, a replaceable removable compliant inner sleeve member (ISM) in nonadhesive intimate contact with and surrounding the core member, and a replaceable removable photoconductive outer sleeve member (OSM) in nonadhesive intimate contact with and surrounding the ISM; electrostatically transferring the toner image, from the PIFM to a counter-rotating intermediate transfer member (ITM) which is a second double-sleeved roller, in a first transfer nip width produced by a pressure contact between the PIFM and the ITM, an electric field urging the toner image from the PIFM to the ITM, wherein the ITM includes a rigid cylindrical core member, a compliant ISM in nonadhesive intimate contact with and surrounding the core member, and a compliant resistive OSM in nonadhesive intimate contact with and surrounding the ISM.

A protective enclosure for an image-recording drum of the type used in electrophotographic printer/copiers comprises a pair of spaced guides that serve to slidably support the drum within the enclosure. Such guides, when aligned with similar drum guides located within a printer/copier frame, enable the drum to be transferred from the enclosure to the copier/printer by merely sliding the drum from one pair of drum guides to the other. A mounting mechanism operates to couple the drum enclosure with the printer/copier frame to properly align the respective drum guides. By virtue of the invention, the image-recording drum can be installed in copier/printer without physically contacting the drum's delicate photosensitive surface, thereby eliminating any image artifacts that may arise from inadvertent scratching or marring of the drum surface during installation.

Protective container/installation fixture for image-recording/image-transfer drums

A receiving sheet having a loose toner image on a surface of the sheet is transported from an image member to a fuser by continuing movement of the image member. To prevent disruption of the loose toner image and to accommodate any difference in speeds of the image member and the fuser, air is directed on the image side of the receiving sheet to force the receiving sheet against a curved guide positioned behind the receiving sheet.
