Abstract: Methods, systems, and devices related to a printer system that includes a first primary ink tank holding a dark-colored ink, a second primary ink tank holding a light-colored ink, a first selector valve configured to change a state, a first secondary ink tank connected to the first primary ink tank via the first selector valve, a second secondary ink tank connected to the first and second primary ink tanks via the first selector valve, a second selector valve connected to the first primary ink tank configured to return the dark-colored ink from the print heads to the first primary ink tank, and a third selector valve connected to the second selector valve and the second primary ink tank configured to either return the light-colored ink from the print heads to the second primary ink tank or to direct the dark-colored ink to the second selector valve.

Abstract: Edge hold down (EHD) systems are described herein that enable high print quality to be achieved more consistently, particularly when using substrates that are rigid or include one or more defects. Each EHD system includes a tensioned band for holding down an edge of a substrate as it passes through a printer assembly without impacting the print area. The tensioned band can be affixed between an entry tension assembly and an exit tension assembly disposed downstream of the entry tension assembly in the media feed direction. The tensioned band holds the substrate substantially flat against a transfer belt during printing by applying pressure to the surface of the substrate. The tensioned band generally contacts the surface of the substrate substantially proximate to an outer edge that is parallel to the media feed direction.

Abstract: The disclosed embodiments include a system for generating a unitary ink tank with a three-dimensional (3D) printing process. The system includes a processor configured to execute computer instructions that control 3D printing of an ink tank for a printer system. The system further includes a 3D printer coupled to the processor and configured to, based on the computer instructions, print the ink tank in accordance with a selective laser sintering process that sinters a powdered nylon material to form the ink tank as a unitary that includes a network of passageways configured to route ink of the printer system.
