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: A system for producing three-dimensional objects forms fluid paths within the support structure to facilitate the removal of the support structure following manufacture of the object. The system includes a first ejector configured to eject a first material towards a platen to form an object, a second ejector configured to eject a second material towards the platen to form support for portions of the object, at least one portion of the support having a body with at least one fluid path that connects at least one opening in the body to at least one other opening in the body, and a fluid source that connects to the at least one fluid path of the support to enable fluid to flow through the at least one fluid path to remove at least an inner portion of the support from the object.

Abstract: A system uses microwave energy to remove support material from a three-dimensional printed object with reduced risk of damage to the object. The system includes a microwave source, a three port device, a susceptor, a temperature sensor, and a controller. The controller operates the microwave source to direct microwave energy into a first port of the three port device, which emits the microwave at a second port of the three port device to irradiate the three-dimensional object and melt the support material. Reflected microwave increases as the amount of support material contacting the object is reduced and enters the second port of the three port device, which directs the reflected energy to the susceptor coupled to a third port of the three port device. The controller monitors the signal generated by the temperature sensor and deactivates the microwave source in response to a predetermined condition being reached.

Abstract: A three-dimensional object printer comprises a conveyor having a surface configured to convey a three-dimensional object in a first direction; a leveling assembly configured to level a surface of the three-dimensional object as the conveyer conveys the three-dimensional object in the first direction, the leveling assembly comprising (i) a member, (ii) a roller connected to the member having a cylindrical shape, the roller having an outer surface that moves upon the surface of the three-dimensional object to level a surface of the three-dimensional object, and (iii) an actuator arranged near the member, the actuator being configured to mechanically interact with the member to move the roller with respect to the planar surface of the conveyer; and a controller configured to, as the outer surface of the roller moves upon the surface of the three-dimensional object, operate the actuator to move the roller with respect the conveyer.

Abstract: A printer compensates for printing errors occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates data corresponding to edges of each layer of the object after each layer is printed. Differences between the raster data used to eject the material to form a layer and the data received from the optical sensor are used to modify the raster data that operates a printhead to form a next layer in the object.

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: 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 system treats uneven surfaces of additive manufactured objects to improve the transparency and glossiness of the surfaces. The system operates an actuator to dip the additive manufactured object into a bath of fluid material that is the same as the material used to form the uneven surface to smooth the surface of the object and operates a sprayer to apply another fluid material to a surface of the object that is identified as being rougher based on the object's geometric data. A heater is provided to dry non-UV curable material applied to the object and a source of UV radiation is provided to cure UV curable material applied to the object.
