Abstract: A sheet to sheet electronic skew correction system measures the input skew of each incoming sheet “on-the-fly” with sensors and then adjusts the image electronically to match the skew of the particular sheet. Thus, the image placed on the sheet from a photoreceptor is square with the dimensions of the sheet since the image is an exact match with the skew orientation of the sheet.

Abstract: An image fixing apparatus and an image forming method capable of favorably fixing a toner containing a crystalline resin are provided. The image forming apparatus passes a transfer medium having unfixed images formed of the toner containing a crystalline resin between a heating member and a pressurizing member, thereby fixing the unfixed images, using a cooling unit that controls a surface temperature of the pressurizing member in which the surface temperature is controlled to a melting point of the crystalline resin +30° C. or lower.

Abstract: In a hybrid jumping (HJD) or hybrid scavengeless (HSD) development station used in xerography, a control system avoids arcing conditions in a gap between a donor member and an image receptor. In a set-up operation, a series of test patches are produced while incrementing the AC amplitude in the gap. A change in reflectivity of the patches as a function of the AC amplitude in the gap is measured and the actual width of the gap is thus estimated. An accurate estimate of the gap width can then be used in a control algorithm.

Abstract: A method and apparatus is disclosed for identifying a position of an object in free space using a video image wherein the object is comprised of at least three equidistantly spaced, co-linear beads. The video image is captured on a view plane of a video camera system and represented on a frame memory thereof. Relative positions of the beads on the frame memory are determined and corresponding coordinate positions of the beads in the free space are calculated based upon the determined relative spacings and known camera system geometries. The object may also include an alignment indicator so that the pointing direction of the object can be determined.

Abstract: The present invention relates to a sliding member for an electrophotographic apparatus using a non-porous sheet having a sliding surface including at least a fluorocarbon resin as a sheet-like member interposed between a press member A and a resin film tubular body. The invention also relates to an image fixing device using the sliding member.

Abstract: This invention relates to a method and apparatus for supporting line-conditioned data stream (LCDS) data in a job-oriented environment. More particularly, the invention is directed to a job-oriented system that also has the ability to process LCDS data. In addition, the LCDS data is processed in a manner that will exploit advanced job management functions of the system.

Abstract: A lossless, reversible data embedding technique uses a generalization of least-significant-bit modification. The portions of the signal that are susceptible to embedding distortion are compressed and sent as part of the embedded payload. A prediction-based conditional entropy coder uses unaltered portions of the host signal to improve lossless data capacity.

Abstract: An image fixing method capable of favorably fixing a toner containing a crystalline resin is provided. A transfer medium having unfixed images formed of a color toner containing a binder resin that contains a crystalline resin and a colorant is passed between a heating member heated by way of an external heating unit and a pressurizing member, thereby fixing the unfixed images.

Abstract: In a module for use in a xerographic printer, a substantially single-piece device includes thereon a cleaning blade, seal flap, and side seals for engaging a photoreceptor. The device can be easily replaced when the module is remanufactured.

Abstract: A method and system to print selective pages of color images within a print job having a plurality of pages using selected color improvement options such as black overprint, anti-aliasing, and trapping. The system identifies and selects one or more pages within a single print job having a set of a plurality of pages and is able to apply a plurality of different color improvement operations upon printing pages having color images thereon. A user interface enables the assigning of a first color improvement operation to a first subset of pages within the single print job. A processor determines if the page being processed is a member of the first subset of pages that have the first color improvement assigned thereto and performs the first color improvement operation upon the image data associated with the page when it determines that the page being processed is a member of the first subset of pages that have the first color improvement assigned thereto.

Abstract: In a printing apparatus, verification of the correctness of a particular replaceable module takes place before an operating element of the printing apparatus fully engages the replaceable module. A printing apparatus coupler establishes a communication link with a tag on the replaceable module as the replaceable module is being inserted into the printing apparatus. The printing apparatus coupler receives module identifying information from the tag. The coupler determines from the identifying information whether the replaceable module is appropriate for that location in that printing apparatus, and performs either an acceptance action to accept the replaceable module, or a rejection action to reject the module.

Abstract: A multi-job image buffering system that processes image data. The multi-job image buffering system has at least one memory device that receives an image data. A job information device associates a job information with a portion of the image data and an image identification device associates image information with the portion of the image data. The at least one memory device is capable of receiving the image data from an image source at a first data transfer rate, and transferring the image data to an image sink at a second data transfer rate.

Abstract: A set of solid ink sticks for a phase change ink jet printer has a common printer key element that matches an insertion key in each in stick feed channel insertion opening. The key element is formed in a portion of the perimeter of each ink stick of the set. The key element is the same for all ink sticks of a set of ink sticks intended for a particular model printer. Different sets of solid ink sticks intended for different models of printers have different printer key elements in each set, to prevent an ink stick intended for one model printer from being incorrectly inserted into a different model printer.

Abstract: A non-interactive development system generates a toner cloud in a development zone by an AC biased stationary electrode positioned in contact with the back surface of a movable toned dielectric donor belt having a patterned electrode structure on the front surface thereof. The AC biased electrode produces AC fringe fields near the edges of the patterned electrode structure that cause the generation of a toner cloud for developing an electrostatic latent image. The donor belt is partially wrapped around a magnetic brush to produce a toner loading zone. Isolated patterned electrodes on the donor belt near the entrance region of the toner loading zone are biased to cause unloading of toner from the donor belt, while isolated electrodes near the exit region of the toner loading zone are biased to cause toner reloading of the donor belt.

Abstract: An integrated image module for a document scanner includes a one piece die cast housing having a datum element and a support element. An imaging sensor array is enclosed in the housing. An array bias element urges the imaging sensor array against the datum element to provide accurate placement of the sensor array relative to the housing. A transport mechanism is attached to the housing so that the position of the transport mechanism accurately corresponds to the position of the imaging sensor array. The lens and the lamp for illumination are also attached to the housing so that the primary components of the imaging portion of the scanner are contained in a single module.
