  • Patent number: 10752024
    Abstract: A printer includes a main frame, a first roller, a second roller, and a transport belt wound around the first roller and the second roller and transporting a medium by rotating while supporting the medium, and a printing unit that performs printing on the medium. The main frame is configured of a plurality of blocks that are separably connected with one another in the transport direction. At least one of the first roller and the second roller is defined as a roller to be consolidated, the first roller, the second roller, and the transport belt are configured to be consolidated in a consolidation block, which is a block for consolidation, by moving the roller to be consolidated from a deployment block, which is a block where the roller to be consolidated is fixed when the medium is transported, to the consolidation block.

  • Patent number: 10696065
    Abstract: A platen assembly for use in digital printing includes a substrate support adapted to support the substrate thereon to facilitate printing to the substrate. One or more apertures are associated with the substrate support and the platen assembly includes a vacuum chamber in fluid communication with the one or more apertures. A vacuum device is in communication with the vacuum chamber such that vacuum pressure is developed in the vacuum chamber during operation of the vacuum device and a corresponding air flow is developed through the one or more apertures. A method for applying indicia to a textile substrate includes placing the textile substrate on a substrate support surface, and directing air through the textile substrate such that the substrate is drawn against the substrate support surface.
