摘要： A printed structure, and systems and methods for creating the printed structure are disclosed. The printed structure includes a substrate, a first printed image layer, and a second printed image layer printed at least partially over the first printed image layer. The first printed image layer includes a first variable image printed using a first electrophoretic ink and the second printed image layer includes a second variable image printed using a second electrophoretic ink. The first variable image and the second variable image are configured to selectively change their display states upon application of an electric field.

摘要： Disclosed herein is a substrate cooling unit for use with a duplex aqueous ink jet image forming device. The substrate cooling unit including a first cooling roll. a first transport belt, a second cooling roll positioned downstream of the first cooling roll in a process direction and a second transport belt. The first and second transports belts include a bottom layer of a fiber mesh impregnated with a polydimethylsiloxane, where the fiber mesh is selected from cotton, polyester, and nylon. The first and second transport belts include an optional intermediate adhesive layer and an optional top layer of silicone having an extractable level of less than 4 percent. The substrate cooling unit includes an invertor.

摘要： A process including providing a paper substrate; disposing a water soluble precoat composition onto all or a portion of the paper substrate to provide a treated paper; applying an image onto the treated paper using a toner or an aqueous ink to provide an imaged paper; wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate; and wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.

摘要： A development system includes a housing configured for accommodating a developer material which includes toner particles. At least one magnetic roller is positioned within the housing to attract the developer material to a surface of the magnetic roller(s). A continuous developer belt is positioned to attract the toner particles from the at least one magnetic roller to a surface of the developer belt. The developer belt is carried on a plurality of developer rollers. One of the developer rollers is positioned adjacent to an image transfer member, such as a belt or drum, with a photoconductive surface. Some of the toner particles are transferred to a latent image formed on the image transfer member to generate a toner image layer, which is applied to a sheet of print medium.

摘要： Nozzles for an additive manufacturing device and methods for improving wettability of the nozzles are disclosed. The method may include subjecting the nozzle to a surface treatment. The surface treatment may include contacting a surface of the nozzle with one or more surface modifying agents. The surface modifying agents may include one or more of an oxidizing agent, an acid, a base, or combinations thereof. The one or more surface modifying agents may increase an oxygen content of the surface of the nozzle. An inner surface of the nozzle may have a water contact angle of greater than 1° and less than about 90°. The inner surface of the nozzle may be free or substantially free of a coating.

摘要： Disclosed herein is a release fluid, a fuser member and an image forming apparatus. The release fluid is a blend an amino functional silicone fluid and a non-functional silicone fluid. The amount of the amino functional silicone fluid is from about 10 weight percent to about 90 weight percent of the release fluid. The amount of the non-functional silicone fluid is from about 10 weight percent to about 90 weight percent of the release fluid. The amount of silanol (Si—OH) is less than 200 ppm in the release fluid.
