  • Patent number: 5600762
    Abstract: A method of processing a job, with compound segments, in a printing system is provided. The method includes the steps of (a) generating a dialog, having a set of attributes designating a manner in which compound segments of the job are to be processed by the printing system, and (b) programming the dialog so that values are provided for selected ones of the set of attributes. The method further includes the steps of (c) capturing the attribute values, programmed in step (b), to obtain a job ticket for a first one of the compound segments and (d) repeating steps (a) -(c) for one or more other compound segments to create a composite job ticket. The compound segments are then processed, in accordance with the composite job ticket, so that one or more copies of the job are delivered to one or more output/storage destinations.

  • Patent number: 5600416
    Abstract: An apparatus for tensioning wires in a wire module assembly is disclosed. Prior to placing the wire module in an operable position, the wires are attached to the wire module and the tension is adjusted to obtain the proper operating tension. This is accomplished by having a fixed and an adjustable wire anchor support. The adjustable anchor support is positioned between two fixed cross members and an adjusting mechanism passes through a cross member, the adjustable anchor support and the other cross member. When the adjusting mechanism is turned, the adjustable anchor support translates between the two cross members.

  • Patent number: 5600126
    Abstract: The present invention presents an apparatus and method for efficiently and automatically monitoring and adjusting the power output of laser diodes used to provide the scanning beams in a ROS system. Light radiated from the back facet of the laser diode is directed onto at least a pair of back facet photodiodes. The photodiode outputs are proportional to the power output of the laser diode associated with the photodiode. The polarization of the laser diode back facet output is controlled so as to ensure that the only outputs from an associated laser diode is sensed by an associated photodiode. In one embodiment, a half wave plate is used to rotate the polarization of one of the laser diodes and in another embodiment optical fibers efficiently transmit light emitted from the back facets to the photodiode.

  • Patent number: 5600404
    Abstract: Specific pattern images are transferred from respective photoreceptors onto the circumferential surface of a transfer belt. By detecting the specific pattern images with sensors, misregistration amounts on a transfer belt are calculated by a misregistration correction control section. Averages of the misregistration amounts for respective colors are calculated for each region that corresponds to a single recording medium placed on the transfer belt. The scanning timings of image writing units are controlled by an image signal output control section based on the calculated averages. As a result, toner images formed on the respective photoreceptors are transferred to proper positions of any recording medium being placed on the transfer belt.

  • Patent number: 5598204
    Abstract: A method for forming a plurality of halftone density patterns in an image processing system. Each density pattern is formed using a halftone cell that is incrementally grown according to a pixel growth pattern that is defined by the position of each threshold value in the halftone cell. The plurality of halftone density patterns are formed in accordance with at least two tests, one for an upper gray density boundary U(d) and one for a lower gray density boundary L(d). The two gray density boundary tests enables different density patterns having the same number of pixels but different densities to be formed by altering the growth pattern of the halftone cell. The two boundaries U(d) and L(d) define a valid range for each gray density threshold in a halftone cell. The defined range insures that pixels are added or removed along the pixel growth pattern of the halftone cell, thereby altering the perceived density of halftone density patterns having an equal number of pixels.

  • Patent number: 5598484
    Abstract: Apparatus for encoding an image signal which is capable of improving the quality of a reproduced image with respect to not only a general image in which electric power is concentrated in low-frequency region coefficients but also an image where the electric power is concentrated in a high-frequency region. The apparatus comprises a blocking device in which a rectangular area in an image is detected from a digital image signal as a pixel block, and is subjected to an orthogonal transform by a converter to obtain a transformed coefficient. In addition, an activity calculator calculates the variance of the image within the block, and electric power to be preserved during encoding is determined by a power-preservation-rate determining device on the basis of the variance determined.

  • Patent number: 5597419
    Abstract: An apparatus and method for moving a cleaning brush, periodically or continuously, to avoid flat spots or voids in the cleaning brush fibers when the printing machine is in standby or off. Periodic movement of the cleaning brush or slow rotation of the cleaning brush when the machine is in a non-operational mode prevent brush "set" from occurring thus, preventing motion quality errors in the printing operation.

  • Patent number: 5598192
    Abstract: An ink jet printer includes a printhead having a plurality of segments each having ink ejecting nozzles, each segment supplied with ink of a different characteristic. Means are provided for moving the printhead in a direction transverse to the advancing movement of a recording medium. Means are further provided for moving the printhead between two or more positions along the recording medium advance direction. Thus, the printhead can print a swath of ink of a first characteristic from one segment and then be moved to print a second swath from a second segment with ink of a second characteristic. In one embodiment, a printhead has two segments, one printing in black, and the other in color. A shift mechanism is enabled to move the printhead between a black print position and a color print position. The invention contemplates alternate color printing swaths at alternate printing positions along the same printing swath, or a combination thereof.

  • Patent number: 5598181
    Abstract: A method for rotating an image clockwise or counter clockwise by ninety degrees in place in an image buffer with a small auxiliary buffer is disclosed. The image, defined by a rectangular pattern of H lines with each line having W pixels, is segmented into square blocks of N pixels per row and N lines per column. The image is stored in an image buffer, and each square block of pixels in the image buffer is rotated by ninety degrees. A starting memory location in the image buffer is selected from a set of starting memory locations, and a memory word at the selected starting memory location is copied into a memory word of a temporary storage buffer. A replacement memory location in the image buffer is determined for the memory word in the temporary storage buffer, which is swapped with a memory word at the replacement memory location.

  • Patent number: 5597413
    Abstract: A release agent management system including a metering roll supported for contact with release agent material contained in a sump. The metering roll also contacts a donor brush structure which, in turn, contacts a heated fuser roll member.The ends of the brush structure are provided with a pair of friction devices which contact the surface of the heated fuser roll member and do not contact the metering roll. Thus, the donor brush structure and the heated fuser roll member are frictionally coupled so that positive rotation of the heated fuser roll member imparts rotation to the donor brush structure.
