Abstract: A printer for producing a print media moving in a process direction including a print engine, a fuser, a full width array and a duplexing path. The print engine is operatively arranged to receive the print media and to apply a first dry marking material to a first surface of the print media. The fuser is arranged subsequently to the print engine in the process direction and is operatively arranged to receive the print media with the first dry marking material applied to the first surface of the print media and to fix the first dry marking material on the first surface using at least one of heat and pressure. The full width array is arranged subsequently to the fuser and is operatively arranged to obtain a first image of the first surface of the print media, the first image being used to quantify a flatness of the print media and/or image quality of the first image. The duplexing path is arranged subsequently to the full width array.

Abstract: 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.

Abstract: A support material toner particle for use in xerographic additive manufacturing includes a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer to be within about 1° C. to about 20° C. of a desired build material toner Tg. A xerographic toner system includes a build toner material and a support toner material, the support toner material includes a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer to be within about 1° C. to about 20° C. of the build material toner Tg. A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.

Abstract: 3-D printers include a transfuse station having at least one roller on one side of an ITB supporting the ITB, and a transmission device on the same side of the ITB. A charge neutralizer is included on a second side of the intermediate transfer surface. The charge neutralizer outputs an opposite charge to neutralize existing static charge on a layer of the build material and the support material on the ITB, before the layer reaches the transfer station. Additionally, the intermediate transfer surface transfers the layer to a platen each time the platen contacts the second side of the intermediate transfer surface, at the transfer station, to successively form layers of the build material and the support material on the platen. Also, the transmission device outputs acoustic waves to cause the layer to move from the intermediate transfer surface to the platen, or to the layers on the platen.

Abstract: A system and method are provided wherein, in at least one form, artificial intelligence is used to identify objects in a document to be considered for metallic rendering or printing on a substrate. Then, the options for printing, including the considerations for rendering in metallic toner or ink, are, in at least one form, presented to the user for acceptance or rejection before the actual printing is initiated.

Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined by examining optical density of some halftone or solid patch versus laser current level. The apparatus and method uses a variable current signal to dither or perturb the laser imaging system to irradiate a fountain solution layer to create patches at different laser current levels. An aptly programmed controller then process optical density measurements to indirectly estimate fountain solution level.
