20080237974 | SYSTEMS AND METHODS FOR REDUCING REGISTRATION ERRORS IN TRANSLATING MEDIA SHAFT DRIVE SYSTEMS - Systems and methods for positioning a sheet in a feed path including at least one sheet drive roller driven in a rotational direction by a drive shaft in which the drive shaft translates in a lengthwise direction along the axis of the drive shaft. A power shaft rotates about the same axis as the drive shaft and is driven by a power source that is fixedly mounted in the system. The power shaft is fixed to the drive shaft by a flexible coupling that allows the drive shaft and the power shaft to move relative to one another in the lengthwise direction along the axis while maintaining corresponding rotational motion between the power shaft and the drive shaft. | 10-02-2008 |

20100053664 | RUN COST OPTIMIZATION FOR MULTI-ENGINE PRINTING SYSTEM - In accordance with one aspect of the present exemplary embodiments, a method for scheduling at least one print job for a plurality of printers of a given type is provided. The method includes determining a job length for the at least one print job. The method further includes scheduling a sequence of printing by the plurality of printers based the job length such that a subset of the available plurality of printers is cycled up, and printing the at least one print job with the subset of available printers when the job length is less than at least one predeterminable threshold. | 03-04-2010 |
20100091319 | SYSTEM AND METHOD FOR PRINTING QUEUED PRINT JOBS - A system for printing queued print jobs includes a user interface and a job submission component. The user interface communicates user input. The job submission component submits print jobs to at least one print queue. The job submission component communicates with the user interface to receive the user input therefrom. The job submission component includes at least one parameter associated with printing an identification sheet with all of the at least one print job in the at least one print queue when a predetermined condition occurs, the predetermined condition includes at least one of a temporal condition, a periodic temporal condition, a threshold number of pages, and a threshold number of print jobs in the at least one print queue. | 04-15-2010 |
20100102501 | FRICTION RETARD FEEDER - Sheet feeding systems and methods for using such systems to feed a sheet from a stack in a document processing system are disclosed. An exemplary sheet feeding system may include a feed roll, a retard system, a trailing edge retention system and a system for automatically an selectively separating the feed roll and the retard system. The feed roll may be configured to drive a first sheet of a stack of sheets in a process direction. The retard system may be configured to prevent one or more second sheets from being driven in the process direction. The trailing edge retention system may be configured to automatically and selectively retain one or more second sheets in the stack by applying a force to a trailing portion of at least one second sheet, thus allowing the feed roll and retard system to be separated during much of the feed cycle. As a result, wear of the feed roll and/or retard system may be reduced. | 04-29-2010 |
20100209169 | MEDIA HOLD-DOWN DEVICE USING TENSIONED THIN GUIDES - A print system including a print head array configured to print ink onto a printable medium, a transport surface positioned adjacent to the print head array and configured to transport a printable medium past the print head array and a plurality of thin guides positioned between the transport surface and the print head array, the plurality of thin guides held in tension and configured to prevent edges of a printable medium from contacting the print head array as the printable medium passes under the print head array. | 08-19-2010 |
20110018190 | MEDIA TRANSPORT SYSTEM WITH SHAFT-MOUNTED NIP LEAD-IN ELEMENTS - A media transport system comprising a roller system, a baffle, and at least one lead-in guide positioned to guide a sheet towards the roller system. The roller system includes a drive roller and an idler roller forming a nip, each roller being mounted on a corresponding drive shaft and an idler shaft, respectively. The lead-in guide, lying at an angle to the baffle, is coupled to at least one of the drive shaft or an idler shaft. The mounting of the lead-in guide eliminates tolerances between the lead-in guide and the nip due to baffle flatness, or baffle and shaft deflections as the lead-in guide is positioned by the drive shaft that locates the nip roller. This arrangement enables the lead-in guide to direct a leading edge of the sheet substantially close to a tangent plane of the nip and minimizes drive forces in the system. | 01-27-2011 |
20110089627 | GATE SYSTEM DIVERTING SHEETS INTO MULTI-WAYS - According to aspects illustrated herein, there are provided systems for conveying a sheet article into an intended pathway. The multi-way gate system for diverting sheets into multiple pathways in a sheet conveying device includes at least three pathways for directing the sheet from the sheet conveying member in a particular direction. A single gate plate is between the sheet conveying member and the pathways. The single gate plate is rotatable about a single axis to direct the sheet exiting the sheet conveying member toward one of the pathways. | 04-21-2011 |
20110135371 | Printing system architecture with center cross-over and interposer by-pass path - A printing system comprises a paper path architecture for parallel printing using multiple marking engines. The media path configuration enables all the media feed trays to be located in one place, relative to the marking engines. A cross-over module is located between marking engines. The cross-over module can interleave media sheets that are being transported away from a first marking engine with the sheets being transported to the second marking engine. The cross-over module also includes a straight through path that enables media sheets to be transported directly to a finishing device without going through either marking engine. The marking engines include internal duplex loops such that media can be supplied to each engine in alternate groups. A merge module selectively merges the media which can then be further processed in a finishing transition module prior to communication to a finishing device. | 06-09-2011 |
