    • A liquid ejecting apparatus has a head, a transport mechanism, a memory, and a controller. The head ejects a liquid. The transport mechanism transports a medium in a transport direction with respect to the head in accordance with a target transport amount that is targeted. The memory stores a plurality of correction values, each of the correction values being associated with a relative position between the head and the medium, a range of the relative position to which that correction value is to be applied being associated with that correction value. In the case where a transport using the target transport amount is performed beyond the range of the relative position associated with the correction value that is associated with the relative position before the transport, the controller corrects the target transport amount based on the correction value associated with the relative position before the transport and the correction value associated with the relative position after the transport.

    • A liquid ejection apparatus includes an ejecting section, an upstream-side transport roller, a downstream-side transport roller, and a control section. The ejecting section ejects liquid onto a medium. The upstream-side transport roller is positioned closer to an upstream side than the ejecting section in a transport direction of the medium, and the downstream-side transport roller is positioned closer to a downstream side than the ejecting section. The upstream-side transport roller and the downstream-side transport roller transport the medium in cooperation with each other by rotating. The control section forms a first pattern by causing the ejecting section to eject the liquid onto the medium in case that an upstream-side end section of the medium in the transport direction is sandwiched with a sandwich section of the upstream-side transport roller. Besides, the control section causes the upstream-side transport roller and the downstream-side transport roller to transport the medium until the upstream-side end section of the medium on which the first pattern is formed becomes positioned closer to the downstream side than the sandwich section in the transport direction and ceases to be sandwiched with the sandwich section, and forms a second pattern by causing the ejecting section to eject the liquid onto the medium the upstream-side end section of which is not sandwiched with the sandwich section.

    • A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row. After forming the second pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row so that a carry amount of the medium after forming the first pattern is longer than the length in the carrying direction of the nozzle row. A fourth pattern that forms a boundary with the third pattern is formed on the medium with the nozzles on the carrying direction downstream side of the nozzle row.
