摘要： 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.

摘要： A mechanism for replenishing particulate material from a receptacle to a remote reservoir. The replenisher mechanism includes a housing having a sensor for sensing the level of particulate material within the housing, pair of spaced end walls, and a pair of spaced side walls. At least a portion of the side walls are flexible. An interface provides flow communication of particulate material between a particulate material receptacle and the housing, and a delivery assembly provides flow communication of particulate material between the housing and a remote reservoir. At least one paddle assembly is operatively associated with at least one of the flexible side walls for moving such side wall in a manner to substantially prevent agglomeration and flake production in the particulate material within the housing. The paddle assembly includes a first pivot rod mounted in fixed spatial relation to the housing, a paddle supported on the first pivot rod, a second pivot rod carried by the paddle. A reciprocating actuator arm is connected to the second pivot rod to selectively move the paddle about the first pivot rod. A lever is pivotably mounted on the second pivot rod, whereby when the paddle is rotated about the first pivot rod by reciprocation of the actuator arm, the lever rotates about the second pivot rod providing movement of the flexible membrane adjacent to the first pivot rod causing the breaking of any particulate material bridges at that point.

摘要： An interface member providing flow communication of particulate material between a particulate material receptacle and a housing of a mechanism for replenishing particulate material from a receptacle to a remote reservoir. The interface member includes a casting defining a flow communication passage. A plate is attached to the casting at an angle to the horizontal to define an angled entrance to the casting. A member, associated with said angled entrance plate, is provided for guiding and holding the marking particle receptacle at a corresponding angle to the horizontal when the receptacle is installed on the angled entrance plate, whereby the angled orientation of the receptacle lets air percolate into the receptacle while the receptacle is emptying, allowing the particulate material to flow freely out of the receptacle.

摘要： A mechanism for replenishing particulate material from receptacles to a reservoir, which provides a highly accurate and continuous indication of the amount of particulate material remaining in the housing of the replenisher mechanism. The replenisher mechanism includes a housing having a plurality of discrete sensors for sensing the level of particulate material within the housing, a delivery assembly which provides flow communication of particulate material between the housing and a remote reservoir, and has a delivery assembly sensor that senses the amount of particulate material delivered by the delivery assembly. A logic and control unit operatively connected to the housing level sensors and the delivery assembly sensor continuously determines the amount of particulate material remaining in the housing so as to indicate when, and how much, particulate material to add to the housing.

摘要： 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.

摘要： An electrophotographic (EP) printer prints on a receiver sheet moving on a tensioned rotatable transport web with a Young's modulus of at least 1 GPa. The transport web is wrapped around a compliant image-bearing member. Two transfer stations are arranged along the belt, each with a rotatable image-bearing member. The first station has a first rotatable nip-forming member disposed adjacent to the transport web on the opposite side thereof from the first image-bearing member. The first rotatable nip-forming member is relatively stiffer than the first image-bearing member. The second station has a nip-forming member on a compliant mount. The second rotatable nip-forming member is relatively less stiff than the second image-bearing member.

摘要： Correction data is produced for density errors in prints produced using a printer. While printing a test image, the periods of rotation of one or more rotatable imaging members arranged along a receiver feed path in the printer are measured using respective period sensors. The printed test image is measured along a selected measurement direction and a reproduction error signal representing deviation from aim density is determined. For each period sensor, the autocorrelation of the reproduction error signal for the corresponding period is determined. If the determined autocorrelation exceeds a selected threshold, the reproduction error signal is decomposed at the corresponding period to extract the variation from the measured component. The remaining error signal is separated by frequency terms. The variations from the data at measured periods and the remaining error signal are used to produce a correction signal.

摘要： An electrophotographic (EP) printer for transferring a toner image to a receiver sheet has a tensioned rotatable transport web with a Young's modulus of at least 1 GPa. The transport web is wrapped around a compliant image-bearing member. A compressible, rotatable nip-forming member that is relatively less stiff than the image-bearing member is adjacent to the transport web on the opposite side thereof from the image-bearing member. A mount holds the nip-forming member against the image-bearing member, and permits the axis of rotation of the nip-forming member to move closer to or farther from the transport web. When the leading edge of the receiver on the web engages with the image-bearing member, the nip-forming member compresses. The axis of rotation of the nip-forming member translates by an amount less than the thickness of the receiver sheet minus the compression of the compliant coating of the image-bearing member.
