Patent number: 8854675Abstract: In the method and device, electronic documents are created from a batch of physical documents of varying lengths. The batch comprises sub-batches of groups of multiple multi-page physical documents with separator sheets on each group. Each separator sheet is marked with a page count for any physical documents in its group. The batch is scanned-in and the resulting image pages are used to form the electronic documents. Specifically, the image pages are analyzed in sequence to identify document sheet image pages and separator sheet image pages. When a separator sheet image page is identified, the page count on that separator sheet image page is read and electronic document(s) is/are created from sequential set(s) of document sheet image pages, which follow the separator sheet image page and have the specific page count, until the next separator sheet image page is identified. This is repeated for all separator sheet image pages identified.Type: GrantFiled: March 28, 2013Date of Patent: October 7, 2014Assignee: Xerox CorporationInventors: Robert St. Jacques, Jr., Steven R. Moore

Publication number: 20140265110Abstract: An articulating sheet guide is used in connection with a printing system. A primary media transport nip is disposed adjacent a media sheet source supplying a media sheet. A secondary media transport nip is downstream. A link has a front surface facing upstream, and a proximal end pivotally mounted. From adjacent the primary media transport, the link will pivot past the secondary media transport. A link pocket is disposed transversely to the process direction on the link front surface. The V-shaped link pocket is adapted to receive the media leading edge. The primary media transport nip will move the media sheet toward the link. The link pocket will receive the media leading edge. The media sheet movement will cause the link to move in an arcuate path guided by the pivotal movement of the link into engagement by the secondary media transport nip. The link pocket will release the media leading edge. The operation is nearly silent.Type: ApplicationFiled: March 18, 2013Publication date: September 18, 2014Applicant: Xerox CorporationInventor: Steven R. Moore

Publication number: 20140233080Abstract: A multiple-beam imager includes multiple light sources (e.g., laser diodes) that transmit light beam pulses (energy doses) along parallel paths onto print plate spots disposed in a circumferential target region during each imaging period. The beam pulses are coordinated with rotation of the imaging cylinder such that, as a selected print plate spot is rotated through the target region, it is sequentially positioned during successive imaging periods to receive light beam pulses from each of the sequentially-aligned light sources, whereby the selected print plate spot receives multiple energy doses (e.g., one during each raster-scan) as it passes through the target region, thereby gradually heating and then evaporating the fountain solution predisposed over the selected print spot. A polygon mirror is used to raster-scan the beam pulses along parallel raster-scan zones.Type: ApplicationFiled: February 15, 2013Publication date: August 21, 2014Applicant: Xerox CorporationInventor: Steven R.

Patent number: 8746694Abstract: A sensing method and system to protect printer print heads from substrate media contact comprising a trip wire sensor to detect and signal a printer control system that substrate media carried by transport media is positioned to strike or contact the print head. The trip wire sensor is located upstream of the print heads, a controlled distance above the transport media in the direction normal to the plane of the media, and comprises a trip wire operatively connected to at least one transducer. Substrate media exceeding the height requirements associated with the print heads contact the trip wire sensor causing the generation of an electrical signal which is received by the printer control system which then takes corrective action to prevent damage to the print heads, for example, by raising the print heads further away from the transport media and allowing the non-conforming substrate media to pass through and be purged.Type: GrantFiled: October 5, 2012Date of Patent: June 10, 2014Assignee: Xerox CorporationInventors: Steven R. Moore, Peter Knausdorf, Michael D. Borton, Joannes N. M. deJong

Patent number: 8690276Abstract: A printer and method of printing wherein a preview mode conveys media through the printer in a manner that avoids the possibility that the media can contact a print head. A hold-down system of the printer and/or media transport generates a hold-down pressure applied to the substrate media in the direction of the first media transport. A precurler unit applies a predetermined degree of curl to the substrate media. A media height sensor determines the height of the substrate media above the first media transport under the influence of the hold-down pressure. A print head array marks the substrate media with an image in the marking zone, and an actuator adjusts the relative spacing between the print head array and the first media transport. The gap between print head and the media is adjustable in view of the measurements.Type: GrantFiled: March 19, 2012Date of Patent: April 8, 2014Assignee: Xerox CorporationInventor: Steven R. Moore

Patent number: 8462380Abstract: This invention generally relates to accurately measuring image geometries in-line within a printing system. One or more two-dimensional array sensors may be located adjacent to a sheet of media printed with a predefined array of indicia marks so that the sensor field of view is contained within the plane of sheet transport. As the sheet is transported by the sensor, the sensors continuously record the locations of the indicia marks within its field of view. The spatial frequency of the indicia marks is arranged so that at least two indicia marks are within the field of view of the sensor at any instant for each of the process and cross-process directions. The two-dimensional array sensor can thus measure the absolute spacing between adjacent local indicia marks within the precision of the sensor construction. The cumulative spacing along each direction may then calculated to determine the overall dimensions of the indicia marks array.Type: GrantFiled: October 16, 2008Date of Patent: June 11, 2013Assignee: Xerox CorporationInventors: Steven R Moore, Chetan Keny

Patent number: 8457529Abstract: Described herein is an exemplary method wherein the photoreceptor surface velocity is nominally set at a speed fractionally different than the intermediate belt (ITB) nominal surface speed. The photoreceptor speed can be preemptively altered through a velocity ramp profile whenever an event is scheduled to occur that will result in ITB transient vibration. As a result, the photoreceptor speed is not allowed to cross over or equal the belt speed at any instant during the transient event. This allows the photoreceptor to remain dynamically decoupled from the ITB, since the apparent disturbance torque imposed by the belt remains constant and does not reverse sign.Type: GrantFiled: November 5, 2010Date of Patent: June 4, 2013Assignee: Xerox CorporationInventor: Steven R.
