摘要： 3-D printing transfers build material and support from an intermediate transfer belt (ITB) to a platen. The build material is the same as the support material, except that the build material includes a photoinitiator and the support material does not. The platen moves to make contact with the ITB, and the ITB transfers successive layers of build material and support material each time the platen contacts the ITB. The platen and a portion of the ITB that is adjacent the platen are heated prior to the platen contacting the ITB, and the same is exposed so as to crosslink polymers of build material, without crosslinking polymers of support material. The polymers of build material being crosslinked and the polymers of support material not being crosslinked makes the support material selectively soluble in a solvent.

摘要： A method of spatially and spectrally calibrating a spectrophotometer including: a) emitting a white light illumination output from a full width illumination source; b) illuminating a test patch with the white light illumination output; c) reflecting a portion of the white light illumination output from the test patch to form a white light reflected illumination output; d) receiving the white light reflected illumination output at first, second and third rows of photosensitive elements to form a first calibration data set; e) emitting a cyan light illumination output from the full width illumination source; f) illuminating the test patch with the cyan light illumination output; g) reflecting a portion of the cyan light illumination output from the test patch to form a cyan light reflected illumination output; and, h) receiving the cyan light reflected illumination output at the second and third rows of photosensitive elements to form a second calibration data set.

摘要： A three-dimensional object printer generates image data of an object being formed in the printer with an optical sensor and identifies the heights of object features above a substrate on which the object is being formed. A controller operates one or more actuators to move the optical sensor at a plurality of distances above the object to generate image data of the object at a plurality of heights above the object. The controller identifies the distances of the features of the object with reference to the image data generated by the optical sensor and the focal length of the optical sensor.

摘要： When performing a printing operation, methods and devices automatically increase a marking material quantity setting when an excessive speed variation condition of a transfer surface is present and an excessive background marking condition is absent. Alternatively, the methods and devices automatically increase tension of the transfer surface and decrease a marking material quantity setting when the excessive speed variation condition is present and the excessive background marking condition is also present. Otherwise, these methods and devices automatically provide a message on the graphic user interface of a printing device when the excessive speed variation condition is present, the marking material quantity setting is at a marking material quantity maximum setting, and the tension of the transfer surface is at a tension maximum. The message provides instructions to use a different type media or initiate a service call.

摘要： A method is disclosed. For example, the method includes printing an image on a substrate, applying an adhesive on select portions of the image, coupling the image to a wave guide such that the adhesive contacts a surface of the wave guide, and providing a light through the wave guide such that the light is emitted through the wave guide and the adhesive and the light is reflected by the select portions of the image back through the adhesive and the wave guide.

摘要： A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes executing a defect learning routine to identify defects, cataloging the defects based on a job function, a type of paper, and a machine state, receiving a job request, determining a known defect that has been catalogued based on the job function, the type of paper, and the machine state, and presenting a visualization of the known defect on a display of a user interface before executing the job request.
