摘要： An electrographic development apparatus has a sump for receiving developer material including carrier particles and toner particles. A magnetic brush receives development material from the sump and moves the material into a position relative to an electrostatic image carried on an insulating surface so that toner particles can be transferred to the electrostatic image to develop such image. A ribbon blender in the sump mixes the toner and carrier particles of the developer material, circulates developer material axially within the sump, agitates and shears the developer material, promotes tribocharging, and feeds developer out of the sump along a path leading to the magnetic brush.

摘要： A support assembly, in an electrostatographic reproduction apparatus having multiple development stations respectively containing different color marking particles for selective development of a plurality of latent image-wise charge patterns on a moving dielectric member so that such apparatus is capable of making multi-color reproductions. The support assembly includes a plurality of members adapted to receive the plurality of development stations respectively. The plurality of members are simultaneously movable to a first position where development stations received by the members are remote from the dielectric member to facilitate removal of such development stations from the apparatus, and to a second position where such development stations are in juxtaposition with the dielectric member. Additionally, the plurality of members, once in said second position where development stations received by the members are located to bring marking particles into development contact with the dielectric member, are independently movable to a third position where such development stations are located to prevent marking particles from coming into contact with the dielectric member.

摘要： Magnetic brush development apparatus wherein flow of developer material, distributed in balance across the length of the apparatus, is assured. The apparatus includes a sump containing a supply of developer material. A magnetic brush is spaced from the sump. A feed mechanism, located within the housing between the sump portion and the magnetic brush transports developer material from the sump to the magnetic brush. A ribbon blender, located in the sump, agitates and transports developer material to the feed mechanism. The pitch of the blender blades self adjust as a function of developer imbalance. As material builds up, the blades's pitch angles decrease, reducing the rate of material transport toward areas of maximum build up. Thus, for a blender where the desired flow pattern is end-to-end, the end of the other ribbon near the end of the station toward which material is transported by the outer ribbin is self adjusting. Similarly, the portion of the inner ribbon near the end of the station toward which material is transported by the inner ribbon is self adjusting. The end result is a mixing device that self balances.

摘要： A digital printing system for printing on a continuous web of print media includes a support structure that guides a continuous web of print media under tension through the printing system. The continuous web of print media includes an edge. The support structure includes a first mechanism, a filter mechanism, and a section in which cross track motion of the continuous web of print media is not desired. The first mechanism is affixed to the support structure and includes structure that positions the print media in a cross track direction. The filter mechanism sets an angular trajectory of the print media, is located downstream relative to the first mechanism, and passively filters fluctuations in position of the edge of the continuous web of print media. The section in which cross track motion of the continuous web of print media is not desired is located downstream relative to the filter mechanism.

摘要： A method of processing photographic media carrying a plurality of images, and an apparatus which can execute the method. The media is scanned to obtain image signals corresponding to the images. Image characteristics are determined from scanned image signals. Image characteristics for scanned images are automatically compared with one or more predetermined characteristic values to classify as passed or suspect images those images which do or do not meet one or more predetermined characteristics. Simulated images are displayed based on the scanned image signals such that any suspect images are apparent to a user. User inputs are obtained for any suspect images, and any suspect image signal is corrected in response to the user input for that image. The image signals are forwarded to an output device.

摘要： An improved transfer apparatus for use in an electrostatographic copier including a dielectric member adapted to carry electrostatically developed marking particle images. The transfer apparatus comprises a cylindrical roller mounted for rotation about its longitudinal axis and located such that its peripheral surface is in operative relation with the dielectric member of the copier. A receiver member is selectively tacked, at least at its lead marginal edge, on the peripheral surface of the roller by vacuum attraction, such vacuum being effective through ports in the roller. At least one trough is formed in the roller substantially aligned with the vacuum ports. Such trough minimizes contact of the tacked lead edge of the receiver sheet to the peripheral surface of the roller, thereby facilitating release of the sheet from the roller at a desired time.

摘要： A reproduction apparatus includes a mechanism for transporting a web carrying electrostatically held toner images through an endless path. The web includes a plurality of closely spaced perforations along an edge. A transfer device includes a drum for presenting a receiving surface to the web to receive a plurality of images in registery, for example, color separation images that will make up a multicolor image on the receiving surface. The transfer drum is driven through a gear train by a sprocket which engages the perforations. The sprocket may also drive the web. To assure the most accurate registry despite inaccuracies in the gear train or perforation location, the pitch of the images on the web divided by the circumference of the sprocket is an integer, preferably 1 and preferably, the circumference of the sprocket divided by the circumference of each of the gears in the gear train is an integer.

摘要： A transfer roller apparatus for use for example in an electrographic copier including a dielectric member adapted to carry electrostatically developed marking particle images on successive image receiving areas. The transfer roller apparatus, is driven to synchronize transfer roller rotation with dielectric member movement for accurate transfer of marking particle images to a receiver member on such roller peripheral surface. The roller transfer apparatus includes a gear train having a first gear coupled to a rotational motive source and a last gear coaxially coupled to the transfer roller. The transfer roller is articulatable to a first position in operative relation with the dielectric member, a second position in operative relation with a cleaning mechanism for the peripheral surface of the roller, and a third rest position intermdiate the first and second positions. Articulation of the transfer roller is effective about an axis which is coincident with an intermediate gear in the gear train whereby the gears in the gear train remain in mesh during articulation of the roller to maintain the synchronous relationship between the roller and the dielectric member.
