Abstract: A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead having a number of inoperative inkjets that is greater than the predetermined threshold. The iterative performance of the printhead purges and test pattern analysis is performed automatically prior to the commencement of printing operations with the printer to remove subjective and time-consuming analysis by a printer operator.

Abstract: A three-dimensional object printer has a platen that is configured to facilitate the release of objects formed on the platen. The platen includes a first layer and second layer, the first layer having a coefficient of thermal expansion that is different than a coefficient of thermal expansion of the second layer. A controller in the printer is configured to operate at least one ejector in an ejector head to form a three-dimensional object on the surface of the platen with reference to digital image data and, upon completion of the object, to operate a temperature control device operatively connected to the platen to bend the platen by changing the temperature of the platen and releasing a three-dimensional object from the platen.

Abstract: A processor identifies print defect locations where printing defects occur and a assigns different sensitivity values to different zones of a job image being prepared for printing by a printing engine. The processor changes the orientation of the job image to a revised orientation, relative to print media, to avoid locating one or more high-sensitivity zones of the job image in the print defect locations. The high-sensitivity zones are ones of the zones having a sensitivity value above a threshold sensitivity value. The printing engine prints the job image on the print media at the revised orientation.

Abstract: An inkjet printer detects vibrations within the printer and compensates for the detected vibrations by adjusting a gap between the printheads and the media transport. Additionally, the inkjet printer detects media sheet heights that may cause damage as they pass through the print zone of the printer and adjusts the gap to enable the media sheets to pass through the print zone without contacting the printheads. A method of operating an inkjet printer so configured is also disclosed.

Abstract: A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, a platform comprising at least one multi-rotational wheel, and a processor communicatively coupled to the at least one sensor and the at least one multi-rotational wheel, wherein the processor calculates a desired movement of the at least one multi-rotational wheel based on the position of the print media.

Abstract: The disclosure discloses methods and systems for automatically generating multiple scanned files when scanning a document at a multi-function device. The method includes receiving a multi-page document for scanning from a user. A user interface is provided to the user to input one or more keywords and one or more desired resolution values, where the input resolution values are different from a default resolution value set at the multi-function device. A page of the document is scanned to generate a scanned page of a default resolution value. The scanned page is checked if including the one or more input keywords. Accordingly, the default resolution value of the page is converted to the user desired resolution value. The scanning, checking, and converting are repeated till all the pages of the document are scanned. Multiple scanned files of different resolution values are automatically generated from single scan activity.

Abstract: Various systems and methods maintain a print job of a user in a print queue and identify the user approaching a printing device using a user identification device operatively connected to the printing device. Such systems/methods alter the position of the print job within the print queue (e.g., to a higher priority position) or even begin printing the print job when the user identification device identifies the user approaching the printing device (i.e., before the user reaches the printing device). Systems and methods can also identify the urgency of the user using the user identification device. The amount that the print queue is altered can be based on the amount that the urgency of the user is elevated.

Abstract: An input/output of a system receives an electronic file comprising text. A processor of the system identifies keywords in the text. The processor correlates the keywords to music attributes and matches the music attributes to musical works. The processor determines computer network locations of the musical works. The processor also adds links to the network locations of the musical works to the electronic file to create a music-enhanced electronic file. The input/output outputs the music-enhanced electronic file that now contains the links to the musical works.

Abstract: Techniques for operating a digital printer that includes a media transport and an electronic imager disposed in a path of the media transport are presented. The techniques include: receiving an electronic image of a media sheet obtained by the electronic imager; identifying, from the electronic image of the media sheet, a print-prohibited region of the media sheet; generating a mask representing the print-prohibited region of the media sheet; and electronically storing in electronic persistent memory, in association with an identification of a type of the media sheet, a template comprising information regarding the media sheet type, where the template includes an identification of the print-prohibited region represented by the mask.
