摘要： An image reproduction machine is provided, and includes a paper substrate feeding assembly having a substrate path for feeding a portion of paper substrate; a moveable image bearing member having an imaging path; toner image forming devices along the imaging path for forming a toner image on the image bearing member; an image transfer station along the substrate path for transferring the toner image onto a portion of paper substrate fed by the paper substrate feeding assembly; and a toner image fusing assembly having heat and pressure devices for heating and fusing the toner image onto the portion of paper substrate. The reproduction machine importantly includes a blank paper substrate preconditioning apparatus (PSPA) for changing and stabilizing a size of the portion of paper substrate before it is fed to the image transfer station. The PSPA is mounted along the substrate path and upstream of the image transfer station relative to movement of the portion of paper substrate, and includes heat and pressure devices for preheating and pre-stressing the portion of paper substrate, thereby causing it to change size to an extent not alterable by subsequent application of heat and pressure within the toner image fusing assembly, thus resulting in highly registered quality reproduced toner images.

摘要： A method of achieving optimum optical contrast for detecting registration marks in a multicolor electrophotographic printing machine. The reflectivity of the image carrying member which is usually an intermediate transfer belt is determined. The reflectivity of each of the toners is then determined. If one of the toners has a contrasting reflectivity, while the remaining toners do not contrast then a uniform field of the contrasting toner is imaged and developed and the registration marks for the other toner colors are then developed on top of the uniform field. A void in the field in the shape of the other toner marks is used as the registration mark for the contrasting toner. If all of the toners have a contrasting reflectivity with the belt, the registration marks are imaged and developed directly on the belt.

摘要： A method and apparatus for controlling speed match between a photoreceptor and an intermediate transfer member to prevent image degradation by creating a deliberate speed mismatch. It has been found that slight variations in speed match between a photoreceptor and transfer member will maintain acceptable image quality, however, should the relative velocity between the members change sign, unacceptable image error results. The method herein comprises slewing the velocity of a photoreceptive member over a range of speeds while monitoring the output control signal current of a drive motor. The resulting control signal current has a large oscillation at the velocity at which the speed of the photoreceptor matches that of the intermediate transfer member. A controller is then used to maintain the motor velocity at a speed slightly less than or slightly greater than the intermediate transfer member speed so as to prevent a change in sign of the relative velocity between the two moving surfaces.

摘要： An apparatus for guiding a moving web, particularly in an electrophotographic printing machine of the type having an endless photoreceptor belt supported by a plurality of rolls and arranged to move in a predetermined path through a plurality of processing stations disposed therealong the web being of the type which is supported by a plurality of rolls. A roll for supporting the web and in frictional contact therewith is adapted for rotational movement about a first axis. A roll support in the form of a dead shaft allows the roll laterally move to pivot about a second axis in a direction substantially normal to the predetermined path direction. This is accomplished by supporting the dead shaft on a V-groove roller which rides in a track substantially along the arc of rotation normal to the predetermined path direction. Any web tracking normal to the predetermined direction exerts a friction force on the roll causing the roll to pivot about the second axis as a result of the v-groove rollers moving along the tracks in a direction substantially normal to the predetermined direction such that the roll aligns itself so that its axis of rotation is substantially perpendicular to the direction of travel of the belt.

摘要： The present invention relates to design rules and geometric compensations for image forming devices. The inherent eccentricities of the photosensitive belts or drums and the timing belt speed reduction drive trains of image forming device cause misregistration of the developed latent images. To prevent such misregistration, the timing belt of the speed reduction drive train has a peripheral length which is selected from a range of values dependent on a preselected speed reduction ratio between the driven pulley and the driving pulley. Further, each one of the range of values is an integral improper fraction or integral multiple of the circumference of the driven pulley. Moreover, the driving pulley of the last pulley belt set coupled to the photosensitive member and a driven pulley prior to the last pulley belt set rotate n full rotations as the photosensitive member rotates from the image forming location to the image transfer location. In conjunction, every speed reduction ratio of all pulley belt sets prior to the last pulley belt set is an integer value. Thus, the eccentricities will be self-compensated.

摘要： An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.

摘要： A virtual lobby client automatically interfaces with multiple virtual world instances, each provided by a separate virtual world provider from among multiple virtual world providers, each interfaced with to access a separate virtual world account, to retrieve a separate selection of inventory items from each virtual world account. The virtual lobby client renders an inventory directory index of each separate selection of inventory items within a single lobby interface with at least one selectable option for managing each of the items in the inventory directory from the single lobby interface. The virtual lobby client renders, within the single lobby interface, a separate graphical portal for each virtual account, wherein entry of each of the separate graphical portals triggers the virtual lobby client to automatically open a virtual world specific interface window into a particular virtual world instance provided under the particular virtual world account associated with the entered graphical portal.
