摘要:
A color electrophotographic printing machine, wherein an electrostatic latent image recorded on a photoconductive member is developed with toner of a first color and toner of a second color to form a visible image thereof, the electrophotographic printing machine including a system, for removing contaminates from toner of a first color and toner of a second color moving from a toner dispenser to a developer housing, the system including: a mounting assembly, a filter system mounted on the mounting assembly, the filter system having a screen for permitting toner of the first color to travel therethrough while inhibiting contaminants from traveling therethrough when vibrated; a first vibration driver, operatively connected to the screen, for vibrating the screen; a second filter system mounted on the mounting assembly, the filter system having a screen for permitting toner of the second color to travel therethrough while inhibiting contaminants from traveling therethrough when vibrated; and a second vibration driver being operatively connected to vibrate the screen, and coacting with the first vibration driver, for damping ocillation of the mounting assembly.
摘要:
An apparatus for filtering contaminants from marking particles is provided. The apparatus includes a conduit and a mover for moving the marking particles within the conduit. The apparatus also includes a screen positioned adjacent the conduit so that substantially all the marking particles discharged from the conduit pass through the screen.

An apparatus for filtering contaminants from marking particles within a conduit is provided. The apparatus includes a mover for moving the marking particles in the conduit and a screen positioned adjacent the conduit so that the marking particles pass through the screen. The apparatus also includes an applicator for applying an electrical bias between the mover and the screen to facilitate the passage of marking particles through the screen.

A developer unit includes a housing defining a chamber for storing a supply of toner therein. The developer unit also includes a member for moving the toner in the chamber of the housing and a support structure, projecting from the housing, for supporting the member. The developer unit further includes a bearing located in the support structure. The bearing is spaced from the housing and rotatably supports the member.
摘要:
An apparatus which develops an electrostatic latent image recorded on a photoconductive member employed in an electrophotographic printing machine having a finite, usable life. The apparatus employs a developer material which ages during the life of the electrophotographic printing machine. A continuous supply of carrier granules is furnished to the developer material. The addition of these carrier granules extends the useful life of the developer material so as to correspond to at least the useful life of the electrophotographic printing machine.

A printing subsystem for use in a network printing system, having a database communicating with a client browser, is provided. The database includes a plurality of data sets and the client browser includes a program with a set of instructions for displaying at least one of the plurality of data sets on a user interface display screen. The printing subsystem is disposed remotely of and communicates with both of the database and the client browser. The printing subsystem includes a marking engine and a copy of the program, the program copy receiving the at least one of the plurality of data sets for placing the same in a displayable format. An interface communicates with the program copy for converting the at least one of the plurality of data sets from the displayable format to a printable format, and a print buffer is employed to store the at least one of the plurality of data sets in the printable format in anticipation of producing a print therefrom.
摘要:
A device for metering toner to a predefined toner bed height on a donor member, including a composite trim bar having a support portion and a cutting portion, adjacent to the donor member, attached to the support portion.

In a scavengeless development apparatus, an electrode wire is disposed between a donor roll and a latent image to form a powder cloud of toner to develop the latent image. The donor roll includes a section of increased diameter spaced away from the latent image, and the electrode wire is disposed in sliding contact with the section of increased diameter to obtain a consistent spacing from the main length of the donor roll.
摘要:
An apparatus in which a latent image recorded on a member is developed with a developer material comprising at least carrier granules and toner particles. Toner particles are dispensed into the developer housing and mixed with unused developer material. The toner particles and developer material are advanced along an extended path so that the toner particles are gently mixed and triboelectrically charged to substantially the nominal level prior to contacting the latent image. A system of this type is particularly useful for toner particles requiring extensive gentle mixing to achieve the desired triboelectric charge.

In one embodiment, a fuser roll for fusing toner images onto a substrate includes a substantially rigid core member, a deformable, heat conductive base layer overlaying the surface of said core member, and an outer layer supported on the base layer. The outer layer is formed of a heat conductive, conformable amorphous metal.
