摘要:
A system and method for transporting a sheet of media through a print zone including a media entrance station, a media exit station and a first media transport translatable in a reciprocal manner between the entrance and exit stations. A second media transport transports a sheet onto and off of the first media transport. The second media transport transports the sheet in a first direction as the first media transport is moving in a second opposite direction.

A critical parameter/requirements management process model for managing a development program for a product and an associated product structure-driven critical parameter/requirements management tool and environment is provided. In one embodiment, the process includes a product structure classification scheme, a parameter/requirements classification scheme, a parameter/requirements process and maturity model, and in-process and requirements conformance views. In one embodiment, the tool includes a user interface layer, a business layer, a data layer, and a database. The user interface layer may include a product structure feature group, an add/edit/link feature group, a manage maturity feature group, and a manage conformance feature group. The tool may be implemented as a web server accessible to user workstations operating as thin clients. The tool may be integrated with one or more other product development tools, such as a document-driven requirements management, configuration management, manufacturing/production control system, problem management, and phased product delivery process tools.
摘要:
A combined sheet inverting and buffering system and method including a sheet drive for transporting sheets into a sheet collecting area. The sheet drive is selectively operable to transport the sheets in a first and second direction along a processing path. A holding device can hold a plurality of sheets. The sheet drive and holding device cooperate to compile the plurality of sheets into a stack wherein the sheets overlie each other in a shingled manner. A take away drive is in operative communication with the sheets for individually unloading the sheets from the sheet collecting area.

A retard feeder adapted to separate and advance media sheets comprising a media sheet advancing device including a drive roll and a retard roll. The drive roll and the retard roll include a feed nip therebetween for driving the media sheets at a velocity. A first drive system is provided to selectively drive the drive roll and the at least one nudger roll in a forward direction. A second drive system drives the retard roll through a slip clutch having a torque wherein the slip clutch torque allows the retard roll to rotate at substantially the same velocity as the drive roll when only one sheet is in the feed nip. The retard feeder further includes a motion sensor for detecting a signal when the retard roll stops rotating at the velocity of the drive roll corresponding to when more than one sheet is in the feed nip. The second drive system can selectively vary the velocity of the retard roll in response to the signal from the retard roll motion sensor.

A method of enhancing cut sheet edge hold-down on an imaging transport surface, the method including: (a) moving a cut sheet towards the sheet the imaging transport surface; (b) inducing a desired curl on one of the lead edge and trail edge of the cut sheet before the cut sheet enters the imaging transport surface, inducing a desired curl comprises inducing into the cut sheet a curl tending into the surface of the imaging transport surface.

A method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.

Methods and systems for an ink printing system with a printhead system comprising at least two printheads with one printhead adjacent to a second printhead, the two printheads spaced such that the media can advance a full swath distance between each scan, and the swath printed by each print head system will overlap the stitch points created by each of the printheads.
摘要:
A document scanner, including a document input tray for holding a compilation of documents in a predetermined sequence; a document output tray for receiving documents; an imaging station for scanning each one of said compilation of documents at predefined scanning rate; an imaging transport system for moving the documents received from said document input tray through said imaging station at a first velocity; an inverter, spaced a predetermined distance from said imaging transport system for moving selected documents of said compilation of documents back to said imaging transport system, said inverter having one mode of operation for moving selected documents to said imaging transport system so that a second side of said selected documents is scanned by said imaging station, said inverter having second mode of operation for moving selected documents to said imaging transport system so that said first side of said selected documents are rescanned by said imaging station. There is also provided a processor, in communication with said imaging station and said transport system, for processing image data at a predetermined data rate, said processor includes means for sensing a data rate fault, and means for generating an error signal in response to said data fault to enable said second mode of said inverter, wherein said second mode of operation said imaging transport system moves at a second velocity which is less than said first velocity.

In a shared users printing and mailboxing system, with a shared remote printer with an operatively connecting array of lockable mailboxes, in which system electronic print jobs from different users at different locations may be electronically sent to be printed, which hardcopy print jobs are automatically fed into respective selected lockable mailboxes, wherein the printer has an internal paper path for this printing with sheet jam clearance capability and a system for signaling a sheet jam, and at least one openable printer access door providing access to the paper path for jam clearances; a print job security improvement system with an automatic locking system for electronically locking the printer access door and an access door on the mailboxing system during printing of security sensitive print jobs to prevent access to the internal printer paper path, but automatically unlocking the printer access door after the hardcopies have reached the selected mailboxes if there is no sheet jam signal, and maintaining the printer access door locked if there is a sheet jam in the paper path until the automatic locking system is actuated by entry of an authorized jam clearance access code.
摘要:
An apparatus for use with xerographic equipment or the like automatically applies a plastic U-shaped spline binder strip from a cassette housing a plurality of strips onto a first edge of a document set clamped to a planar surface. A binding strip cassette storage holds a plurality of binding strips for single-file automatic installation onto a series of document sets generated by the xerographic equipment. A spreader member disposed between the cassette storage and the document set opens finger portions of the binding strip as it translates from the cassette and onto the document set.
