An integrated printing system is provided and includes at least two generally vertically aligned image marking engines and at least two generally horizontally aligned image marking engines. The printing system further includes at least one generally horizontal interface media transport for transporting media between and to the vertically aligned and the horizontally aligned image marking engines.

Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

A system and method for registering a sheet includes a lateral motion motor coupled to a nip and idler roller assembly that provides lateral alignment of the sheet. A de-skew assembly pivots the lateral motion motor and the nip and idler roller assembly about a pivot axis that is proximate to the lateral motion motor to de-skew the sheet.

A printable media hold-down system includes a print head array, a transport surface positioned adjacent to the print head array which transports a printable medium past the print head array in a location where the print head array may apply ink to the printable medium, and a vacuum system that creates vacuum pressure that holds the printable medium to the transport surface, the vacuum system having at least one adjustable baffle configured to move in a cross process direction and change a dimension of the vacuum system based on a dimension of the printable medium.

A flexible media integration system (10) includes a multifunction flexible media interface system (12). The interface system includes a plurality of flexible media input areas (22, 24, 26) for receiving flexible media (14), such as sheets of paper, from a plurality of associated input processors (16, 18, 20), such as printers or paper feeders. A plurality of flexible media output areas (32, 34) provide outputs to different associated flexible media output processors (36, 38), such as printers or finishers. The interface system also includes a sheet position sensing system (52) and a sheet transporting system (42). The transporting system provides selectable flexible media translation for selectably transporting flexible media from selected ones of the plurality of flexible media input areas to selected ones of the plurality of flexible media output areas so as to provide selectable flexible media feeding from selected flexible media input processors to selected flexible media output processors.

A multifunction printed sheets interface system with plural sheet input areas for receiving printed sheets from plural printers, plural sheet outputs areas for plural outputs to different sheet processing systems, a sheet position sensing system, and a sheet transporting system providing selectable sheet translation from selected plural sheet input areas to selected plural sheet outputs areas so as to provide selectable sheet feeding from selected printers to selected sheet processing systems, and selectable sheet rotation of selected sheets and selectable sheet merging in a selected sheet sequence of sheets from plural printers. The sheet transporting system has a large planar area with a multiplicity of spaced apart independently operable variable sheet feeding direction and sheet velocity sheet transports, larger than the dimensions of any sheet to be fed thereon to allow simultaneous plural sheet variable transport thereon.

A method and system feeds a sheet through a media path in a process direction. When the sheet is within a sheet registration carriage of the media path, the method and system align the sheet to a predetermined lateral position within the media path. The aligning process comprises unevenly activating nips within the sheet registration carriage and moving the sheet registration carriage in a lateral direction perpendicular to the process direction. If the lateral movement distance exceeds a predetermined distance, the method and system move the sheet registration carriage toward the starting position after the nips have released the sheet, but before the sheet has passed by the nips.

An inductive-type rotary encoder includes a stator having at least one conductive pattern on one side thereof, and a rotor having another conductive pattern on one side thereof which faces the at least one conductive pattern of the stator. The conductive patterns are inductively coupled to one another so as to generate an output signal indicative of the angular position of the rotor relative to the stator. In order to reduce the overall size and number of parts required, the circuitry for energizing the stator conductive pattern(s) and for generating the output signal can be provided on a printed circuit board, the opposite side of which contains the at least one stator conductive pattern. In order to reduce noise as well as to reduce the first harmonic error, lead lines for attaching the stator and rotor conductive patterns to the controlling circuitry and a return line which extends along substantially the entire length of the rotor or stator conductive patterns and attaches to one of the lead lines are provided and specially located relative to undulations of the conductive patterns. Additionally, the length of spokes which define undulations of the respective rotor and stator conductive patterns can be controlled to improve the performance of the rotary encoder. A rotary encoder including inductively coupled rotor and stator conductive patterns for generating a relative angular position (or rotary speed) of the rotor relative to the staator, as well as stator and rotor index pulse patterns inductively coupled for generating an index pulse once per revolution of the rotor relative to the stator is also provided.

Embodiments described herein are directed to characterizing a media curler for a printing. Test curls can be imposed on media having input curls with known input values using a media curler to be characterized. The media curler can impose the test curls based on curler settings of the media curler. Resulting output values from an interaction between the test curls and the input curls can be measured and the curler settings can be characterized based on the known input values and the resulting output values so that the media curler can be configured to respond to incoming media having a known input curl by applying curler setting to achieve a desired output curl.
