摘要:
An improved fuser cleaning purge cycle system of cleaning imaging material from a fuser (particularly, a fuser roll) of a copy reproducing apparatus after an inadvertent interruption of the operation of the apparatus, such as by a paper jam, in which the fuser was potentially contaminated with imaging material from a copy sheet being fused, wherein the reproducing apparatus has an alternative duplex copying path; comprising, automatically, sequentially feeding a preset limited number of preexisting conventional clean copy sheets in the copy reproducing apparatus through the fuser to function as fuser cleaning sheets to remove the potentially contaminating imaging material, then feeding the same fuser cleaning sheets through the alternative duplex copying path back to and through the fuser a second time, with sheet inversion, so that they are inverted before feeding through the fuser the second time, and then purging these fuser cleaning sheets. The fuser cleaning cycle may be automatically initiated in response to sensing that a copy sheet was stopped in the fuser during the interruption of the operation of the reproducing apparatus. Preferably, the preset limited number of sheets used is four or less, yet, preferably, every area of the circumference of a fuser roll is contacted by at least one side of one fuser cleaning sheet a minimum of four times during this fuser cleaning cycle.

A seismic fluid prediction data, e.g., a dataset, is generated for a subsurface region by preconditioning seismic data for amplitude-versus-offset (AVO) analysis. Seismic AVO attribute data is generated for the subsurface region, including creating intercept (A) and gradient (B) seismic data using two or more angle stacks of seismic data. Lithology prediction data is generated with the intercept (A) and gradient (B) seismic data, and an AVO crossplot for fluids is generated to identify an initial AVO anomaly. Seismic fluid prediction data is generated based on the generated AVO crossplot and lithology prediction data.

Methods and systems of assessing color gamut requirements for a print job and a printing device are disclosed. A print job including one or more input color spaces may be received. A computing device may produce a color transformation for each input color space using at least a color gamut error profile. The computing device may further produce result information based on the one or more color transformations. Result information may be provided to a user.

Systems and methods for reducing delays in printing print jobs use a RIP or a digital front end generally, to maintain an inventory of pre-ripped ready to print work that can be sent to the print engine to prevent an engine shutdown due to the RIPs inability to keep up with the engine. The systems and methods for reducing delays in printing print jobs can track performance in real time and automatically switch to printing jobs from post-RIP content archive if it is determined that the print engine is at risk of outpacing the RIP or DFE such that printing will be interrupted at the print engine.

A system and method for enabling production of larger books utilizing a multi-substrate hinged media. A media definition for a specialty media can be enhanced to include information about multiple variants that contain varying sizes of hinge sections related to a specific media and a page assignment rule. The set of hinged media variants can be treated as a single media type and the properties of the media type determine sheet thresholds for each variant. The specific media variants can be assigned to specific document pages based on the page assignment rule. The pages in the center of the book utilize larger hinges to allow the pages to lie flat, while pages at the beginning and end of the book utilize smaller hinges to prevent imaging on the hinge area.

A method is provided for enabling adaptive print job content processing as a function of the electronic format and content of files, received by a digital print production environment providing access to a display in the form of a user interface able to select job content processing options. The method includes receiving a print job in one or more electronic format files, with the print job including supplementary information for one or more electronic format files. Depending on the electronic format of the files, job programming options are structured, with options including parameter(s), parameter value(s), and parameter selectability. Programming options are presented on the user interface for review and possible modification by an operator. A determination is made as to whether any operator modifications have been indicated. If operator modifications have been indicated, the parameter value(s) affected are adjusted.

A method and system for automatically generating page exception programming based on user-defined rules is disclosed. A page specific metadata in a PDL file can be evaluated against specific rules to automatically create page exception programming. An embedded PDL device control instructions can also be evaluated and converted into page exception programming thereby producing an integrating representation of all page exception programming for a print job. The PDL page extracted as an exception page can then be displayed on a graphical user interface which provides an operator to confirm pages for editing.

A method is provided for managing a print job in a distributed printing system including a first printing system having a first default operating mode with a first rated output and a second printing system having a second default operating mode with a second rated output. The method includes determining that the second printing system has the capability to operate in an adjusted operating mode with an effective output that differs from either the first rated output or the second rated output. In practice the print job is split into first and second job portions in such a way that when (a) both the first and second print job portions are communicated to the distributed printing arrangement, (b) the first print job portion is printed at the first printing system in the first default operating mode, and (c) the second print job portion is printed at the second printing system in the adjusted operating mode, printing of the first and second print job portions end substantially simultaneously.

This invention relates to a methods and a printing system in which queues across one or more printing devices, such as printers, copiers, and the like, are automatically kept synchronized. The queues are placed into one or more pools. In some embodiments, one queue in a pool is designated as a master queue. Changes to the queues in the pool are then controlled and propagated from the master queue. In other embodiments, various queues in a pool are designated as peers. Any change to a queue, such as a change to a subset of print job parameters, in the pool is then propagated to its peers.

Embodiments herein include a method of adding color to a monochrome (single color printing) document that begins by inputting/creating colorization rules relating to the previously printed monochromatic document and scanning the previously printed monochromatic document to locate rasterized data. After the scanning, the method performs optical character recognition on the rasterized data to search for text corresponding to the previously printed monochromatic document. After the rules are input and the rasterized data is produced, the method automatically colorizes portions of rasterized content according to the colorization rules and this generates a colorized electronic document.
