Abstract: This invention relates to the packaging and subsequent removal of dry marking materials that tend to clump or bridge when shipped or stored in containers. Human operators are presently instructed to agitate such containers before installation into a marking engine but such agitation is unreliable. The present invention involves placement of agitation vanes on a displaceable inner seal within the cartridge such that such vanes will break apart clumps and bridges of the marking material during installation of the container upon the marking engine.

Abstract: In a document search and retrieval system, document images are segmented into layout objects. Each layout object identifies different structural elements in a document image. In addition, the system computes attributes and features for each segmented layout object. Before any document images are transmitted between a client and a server, users specify which document image attributes and features are most relevant to their browsing or searching tasks. Transmission (and/or display) of document images is then divided into two stages. During the first stage, those layout objects which are identified as having the specified features or attributes are transmitted at a first or high resolution; the remaining layout objects in an image are transmitted at a second or lower resolution (or in the form of bounding polygons). If the second stage is invoked, those remaining layout objects are re-transmitted at the first or high resolution.

Abstract: Annotating activities are associated with portions of recordings by activity/recording data such as a table in which annotation identifiers are paired with timestamps. To obtain activity/recording data, an image input device, such as a manually positionable scanner or a fixed position camera, can produce an image signal set with information about a manual annotating activity and a recording/playback device can provide a recording portion signal, such as a timestamp, with information about a portion of a recording. The image signal set and the recording portion signal can then be used to automatically obtain the activity/recording data, associating information about the manual annotating activity with information identifying the portion of the recording. The information about the manual annotating activity can be an annotation identifier that includes information about the position or shape of the annotation.

Abstract: During the operation of a document processing system machine and job data are collected from a document processing system. Optionally, machine information, both for the specific machine and population based data are acquired from a database or server. Having accumulated the job data and machine data, the diagnostic inference engine performs an analysis to determine the initial diagnosis of the document processing system. After obtaining the initial diagnosis, the system determines the test patterns to be printed and the image quality tests to be performed. The system then prints test patterns, and scans the patterns to determine image quality parameters and/or to automatically identify image defects. Optionally, image defect information may also be provided by the customer or the service engineer via a user interface. Next, a diagnostic inference engine uses the results of the image quality analysis to refine the initial diagnosis.

Abstract: An apparatus for developing a latent image recorded on a movable imaging surface, including: a reservoir for storing a supply of developer material; a first donor member and a second donor member, the first and second donor members both being arranged to receive toner particles from the reservoir and to deliver toner particles to the image surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; and system for moving the outer surface of first donor member at a first velocity; and system for moving the outer surface of second donor member at a second velocity; wherein the first velocity could be slightly different than the second velocity to reduce a ghosting print defect.
Abstract: A symmetrical accounting method and apparatus uses a DSA agent within each node of a computer network. The agents monitor their respective nodes for outgoing and incoming transactions and transparently generate accounting data upon detecting the transactions. The accounting data is temporarily cached for later downloading to an accounting database. The method and apparatus is adaptable to a variety of accounting information through the use of verb sets and user modifiable extension records. The method and apparatus is symmetrical because accounting information is collected on both sides of a transactional conversation or object method to object method call.
Abstract: In a photosensitive imaging apparatus having multiple chips, each chip having a set of photosensors, chips of a single basic design can be instructed to operate consistently with either parallel or serial readout of the apparatus. Signals on a shift register line associated with each chip are recognized, by on-chip circuitry, as an instruction to operate the chip in either a parallel or a serial manner.

Abstract: In an image forming apparatus that forms a toner image on a continuous medium, the tension force applied to the continuous medium by the image forming drum is controlled within a proper range. The apparatus comprises a toner image forming unit forms a toner image on a rotating image forming drum, a transfer unit that transfers, to the continuous medium, the toner image on the image forming drum by a transfer current, and a control unit that monitors the tension force applied to the continuous medium by the image forming drum and controls the transfer current at the transfer area, based on the results of this monitoring. Alternatively, the apparatus increases the minimum printing ratio by adding additional data to the print data.
