  • Patent number: 7758139
    Abstract: 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.

  • Publication number: 20090267984
    Abstract: 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.
