Abstract: A color image forming device produces a good image form, superior in color and gradation reproduction, and little over-enhancement in sharpness during generation duplicating. The device has an image processing parameter storage unit that stores parameters for processing which correspond to original document modes in respective processing blocks. An image processing parameter detector detects the original document mode, and provides the mode to the respective components as an original document mode directive TAG. When generation duplicating is designated, the generation duplicating mode corresponding to the set original document mode is set, and various parameter settings are indicated corresponding to the set generation duplicating mode in the image processing parameter storage unit. By such, the operation in each image processing module is converted to the set generation duplicating mode.

Abstract: An improved method for providing a continuous supply of liquid ink to an ink jet print head is provided. The method maintains an estimate in a memory source of the amount of liquid in a reservoir that is available to the print head. The estimate is periodically updated by information received from an ink sensor in the reservoir. By comparing the estimate to a plurality of ranges, the method determines whether additional ink may be added to the reservoir.

Abstract: An image transfer apparatus cooperates with an image reception and reproduction means to reduce network burden while transferring profile information. Specifically, a profile storage device is connected to a network. The profile storage device stores profile information for a color correction made to color image information on color image information prepared from object information. An image transmission device transmits profile specification information specifying the profile information corresponding to the color image information or the object information together with the color image information or the object information. A receiving device receives the color image information or the object information and the profile specification information transmitted by the image transmission means. A call device requests profile information specified by the profile specification information received by the reception device from the profile storage device.

Abstract: A closed loop control system precisely sets and monitors tension in a photoreceptor belt. A stepper motor is actuated by a controller to apply pressure to a yoke connected to the photoreceptor belt through a steering roll. A strain gauge positioned on the yoke senses the pressure of the yoke against the photoreceptor belt and signals the controller which in turn actuates the stepper motor to bring the tension on the belt to a predetermined set amount. The closed loop control system also increases tension on the photoreceptor belt to improve drive capacity if friction between the photoreceptor belt and a drive roll decreases during operation as sensed by a decrease in driver motor torque.

Abstract: Toner image forming stations form toner images that are electrostatically transferred to the intermediate transfer member. The composite toner image is transferred to the transfuse member at the second transfer nip. The temperature of the transfuse member in the second transfer nip is above the glass transition temperature of the toner image. The toner image is generally transferred and fused to the substrate in the third transfer nip.

Abstract: A target-less calibration system for calibrating a scanner for a particular input medium without using a dedicated calibration target on that medium is disclosed. The system employs the (predetermined) spectral response of the scanner and representative spectral measurements of the input medium to achieve the calibration. The representative spectral measurements of the input medium are used to infer the set of feasible spectra for the medium. Corresponding to a given scanner signal output, another set representing the candidate spectra that could have resulted in the given scanner output are determined using the predetermined scanner spectral response. Combining the two requirements, a spectrum in the intersection of the thus determined sets of scanner candidate spectra and prenoted feasible media spectra provides an estimated spectrum of the input sample. Repeating the process over the range of scanner outputs provides a complete spectral calibration for the scanner for the given medium.

Abstract: A method is described for printing a colorant controlled neutral black object in a bitmap-based digital color printing system. The method is useful in systems where the black colorant is not sufficiently opaque to hide non-neutral combinations of non-black colorants mixed into the black color. Black colors in a color printing system can be composed either of black colorant only or of black plus non-black colorants such as cyan, magenta, and yellow. If the non-black colorants are not mixed in nearly equal quantities, they will add hue to the black color. A sufficiently opaque black colorant can hide this objectionable non-black hue. However, in cases where the black colorant is not opaque enough, it is important to use equal or nearly equal combinations of cyan, magenta, and yellow so that little net hue will be introduced into the black color. Equally important in some printing systems is the ability to control the amount of total colorant used in forming a process black color.

Abstract: A system for guaranteeing that a defective check is destroyed before a duplicate check is printed. A client terminal is connected to a check printer and a shredder. The client requests a check to be printed. If the printing is defective the check is submitted to the shredder, which destroys the check and enables the printer to print a duplicate. To the extent that the client has a more extensive data base than the printer, the destruction of the check is transmitted to the client as well as the printer. In this case it is the client that instructs the printer to print a duplicate. Finally, to the extent that a network is used for communication between the elements, encryption and passwords may be used for security.

Abstract: A color capable electrophotographic printer remains operable for monochrome printing when one or more developing unit are unavailable for use. Instead of reverting to an error state when a developing unit is missing or unavailable, the laser printer remains operable to print monochrome images or single "spot color" images using a single color and monochrome developing unit.

Abstract: A method and apparatus for classification of scanned symbols into equivalence classes as may be used for image data compression. The present invention performs run-length symbol extraction and classifies symbols based on both horizontal and vertical run length information. An equivalence class is represented by an exemplar. Feature-based classification criteria for matching an exemplar is defined by a corresponding exemplar template. The feature-based classification criteria all use quantities, which includes the stroke width of symbols, that can be readily computed from the run endpoints. Reducing the number of equivalence classes is achieved through a process called equivalence class consolidation. Equivalence class consolidation utilizes the symbol classifier to identify matched exemplars indicating equivalence classes which may be merged. For a consolidated equivalence class, the exemplar matching the most symbols is selected as the representative for the class.
