  • Patent number: 10189279
    Abstract: A medium flattening method, when a medium is transported by being adhered to an adhesive layer which is on a surface of a transport belt, includes detecting a presence or absence of floating being generated in the medium on the transport belt using a sensor, executing a process for flattening to flatten the floating in the medium in the case where the floating exists, and transporting the medium, where the floating is eliminated using the process for the flattening, to a liquid discharge region of a liquid discharge section. The executing of the process for the flattening includes executing the process for the flattening with regard to the medium and liquid discharge with regard to the medium in parallel.

  • Patent number: 9298138
    Abstract: A recording apparatus includes a transfer belt which transfers a recording medium, a recording section which performs recording on the recording medium, and a wiper blade which is able to abut with the transfer belt, wherein the wiper blade is supported in a state of being clamped by clamping members. Extension lengths of the clamping members, which are from an clamping region in the direction toward the transfer belt, are different depending on the clamping member. The extension length of the clamping member, which is on the downstream side in the movement direction of the transfer belt to transfer the recording medium during recording, is longer.
