摘要:
A modular conveyor and conveyor system for transporting articles thereon. The functioning of the entire system is integrated by a programmable logic controller (PLC) mounted on each conveyor unit. Where PLCs on adjacently connected conveyors communicate with one another. Each conveyor has sensing devices for communicating with the PLC by indicating the absence or presence of articles located at specific zones on the conveyor. In response to the sensing input, the PLC will send and receive articles to and from adjoining units. All of the movement of articles on the conveyor system are preprogrammed into the PLC, however manual over-ride is provided for. The conveyors have rollers for moving articles along the length of the units. Belts are located at one end for moving articles transverse to the roller movement. Roller-ball racks are used for rotational movement of articles on the unit. The PLC controls the activation of the rollers, belts, and racks of the conveyor in response to the sensor input information.

Fixing systems apply at a fixing nip low or ambient temperatures and moderate pressures or relatively high pressures to a substrate on which marking material is deposited. Fixing systems are integrated with a base print engine of a printing system, or added inline as a module to a printing system. Fixing systems and printing systems containing fixing devices and systems, including multi-stage fixing systems accommodate a broad range of substrates.

In DC pin scorotron charging apparatus for charging a photoreceptor to a final voltage, a first DC pin scorotron charging device initially charges the photoreceptor to an intermediate overshoot voltage and a second DC pin scorotron charging device thereafter uniformly charges the photoreceptor to the final voltage. The first DC pin scorotron charging device provides a generally high percent open control grid area, a generally high emitter slope, and a generally high emitter pin current. The second DC pin scorotron charging device provides a generally low percent open control grid area, a generally low emitter slope, and a generally low emitter pin current.

A real-time photo-induced discharge curve (PIDC) model generator uses a nonliner model structure based on the physics of a xerographic system photoreceptor. The PIDC generator estimates a small number of parameters in the PIDC model in real-time for a given xerographic system configuration. The estimated PIDC may be used by xerographic system process controls, diagnostics and xerographic system setup in real-time.

A process for coating flexible belt seams including providing a flexible belt having an outwardly facing surface and a welded seam, forming a smooth liquid coating on the welded seam, the liquid coating comprising a film forming polymer and a fugitive liquid carrier in which the belt surface is substantially insoluble, and removing the fugitive liquid carrier to form a smooth solid coating on the seam.
摘要:
A cleaning system and process for removing residual toner from an imaging surface, including a primary cleaner system for removing the predominant amount of residual toner and debris and a retractable secondary agglomeration cleaning blade mounted downstream from the primary cleaner, wherein, when the blade is moved into the engaged position, the cleaning edge is engaged with the imaging surface at for shearing release of agglomerations from the imaging surface and wherein the cleaning blade is movable to the retracted position during periods in which the primary cleaner is in its operative position.
摘要:
Image quality of an image generated by a xerographic or equivalent image generating process may develop non-uniform charge characteristics, in addition to other negative effects, as a result of positive over-spray, but these negative effects can be at least attenuated by exposure of the photoreceptor to fluorescent light.
摘要:
A device for transferring electrical charge between a first element and a second element is provided. The elements have relative rotational motion therebetween. The device has a body including a multiplicity of electrically conductive fibers. A substantial portion of the fibers extend in a substantially parallel direction, parallel to a first axis. The body includes a first contact area. The body defines an aperture therein. The body further includes a second contact area on the periphery of the aperture spaced from the first contact area. The first contact area is for contact with the first element and the second contact area is for contact with the second element.
摘要:
A device for transferring electrical charge from an electrically conductive element to a rotating element is provided. The device has a body including a pultruded composite member having a multiplicity of electrically conductive fibers provided with a polymer matrix. The plurality of conductive fibers is oriented within the polymer matrix in a longitudinal direction of the pultruded composite member. The fibers each extend in a substantially parallel direction, parallel to a first axis. The body includes a first contact area. The body defines an aperture therein. The body has a second contact area on the periphery of the aperture spaced from the first contact area and a support. The support is secured to the body for supporting the body. The first contact area is for contact with the conductive element and the second contact area is for contact with the rotating element. The fibrillated portion is coincident with at least one of the first contact area or said second contact area.
