Apparatus for precisely positioning one or more of the work stations of a document printer/copier relative to an internal drum, including a first member, attached to either a work station or the internal drum, having two sections, each section having a reference surface forming an angle therebetween, an actuator for changing the included angle between the first reference surface and second reference surface, thus enabling the included angle to be increased or decreased, and a second member having a reference surface that mates with the pair of reference surfaces, associated with the other of the work station or the internal drum, so as to accurately adjust the work station relative to the internal drum dependent upon the included angle of the first reference surface and second reference surface.

A magnetic brush development station with a housing forming a reservoir for developer material has a plurality of augers located in the housing for mixing developer material. A drive for the plurality of augers includes an assembly having a body extending through the development station housing. A plurality of bearings are positioned in the body with a spacer between the plurality of bearings. A rotatable shaft is connected between the plurality of augers and an auger drive member. A seal for the rotatable shaft has a lip formed of a material which is able to stretch sufficiently to maintain sealing contact with the shaft while the shaft is being rotated by the auger drive member.

Development station for a reproduction apparatus

A magnetic brush development station for a reproduction apparatus. The magnetic brush development station includes a housing forming, at least in part, a reservoir for developer material. The reservoir has a pressure equalization seal. A mechanism is associated with the housing for readily moving the housing relative to the reproduction apparatus. Another mechanism selectively readily replenishes and/or empties at least one component of developer material with respect to the reservoir. A plurality of augers are located in the housing for mixing developer material within the reservoir. A drive for the augers, extending through the housing, has a seal therefor. A development roller, mounted within the housing, delivers developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell such that the core magnet and the shell having relative rotation. The core magnet extends less than the entire length of the development roller such that the developer nap on the shell does not extend to the end of the development roller. A metering skive, extending the length of the development roller, controls the quantity of developer material delivered from the reservoir portion of the housing to the development zone. The metering skive is positioned parallel to the longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. Further, a magnetic seal is located in association with the skive at each end of the development roller. The magnetic field of the magnetic seal is sufficient to substantially prevent leakage of developer material from the ends of the development roller.

A mechanism for adjusting the location of a rotatable mixer and rotatable transport mechanism within the development station housing of an electrographic reproduction apparatus development station. The development station includes a housing, a rotatable mixer assembly located in a developer material reservoir within the housing, a developer device for applying developer material to an electrostatic image to be developed, a rotatable transport mechanism for moving developer material from the reservoir to the developer device, and a drive mechanism for rotating the rotatable mixer, the rotatable transport mechanism, and the developer device. The adjustment mechanism describes a first locating device for adjustably positioning the drive mechanism relative to the reservoir of the development station housing, and a second locating device for adjustably positioning the rotatable mixer and the rotatable transport mechanism relative to the development station housing. The second locating device includes a spacer member for maintaining a predetermined fixed distance between the rotatable mixer and the rotatable transport mechanism.

For use with an apparatus for feeding sheets seriatim from a stack of sheets, the apparatus including a feed tube, such as an oscillating vacuum feed tube for example, defining a plurality of ports through which vacuum is effective for acquiring a sheet from a sheet stack and transporting such sheet from the sheet stack, a device for improving sheet separation and friction feed assist. The disclosed device includes at least one clip associated with at least one port of the feed tube. A friction member is secured to the clip and extends substantially radially outwardly from the oscillating vacuum feed tube so as to cause an acquired sheet to assume a corrugated shape. Accordingly, a sheet of the sheet stack, acquired by the feed tube, assumes a corrugated shape to readily separate from the remaining sheets in the stack, and the friction member assists in feeding of such acquired sheet from the stack.
