摘要： 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.

摘要： A liquid ejecting apparatus includes a head unit, a movement mechanism, and a control section. The head unit has along a first direction a plurality of heads, in which a plurality of nozzles that eject a liquid onto a medium are lined up in the first direction, and the head unit forms a single raster line by ejecting the liquid while performing m number of movements relative to the medium in a second direction, which intersects the first direction. A width of the head unit in the first direction is greater than a width of the medium in the first direction. The movement mechanism causes the head unit to perform a plurality of movements relative to the medium alternately in the second direction and the first direction. The control section forms an image having a resolution that is n times a pitch of the nozzles, by forming a plurality of the raster lines by the plurality of relative movements of the head unit. Further, the control section sets a total movement amount of the head unit in the first direction when the head unit performs the plurality of relative movements, larger than an effective nozzle width of one of the heads in the first direction multiplied by (m×n−1), and smaller than the effective nozzle width×(m×n). Furthermore, the control section forms the image by setting respective movement amounts of the head unit in the first direction when the head unit performs the plurality of relative movements, larger than the effective nozzle width.

摘要： 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.

摘要： A liquid ejecting apparatus includes an upstream-side roller and an downstream-side roller, an ejecting section, and a controller. The controller stores in advance a correction value for correcting a pre-correction target transport amount for transporting the medium, the correction value being associated with a range from a first position to a second position. The controller carries out the transport operation based on a post-correction target transport amount in the case where the controller carries out the transport operation in such a manner as the medium is transported from a third position upstream in the transport direction from the second position to a fourth position downstream in the transport direction from the first position and the third position, the post-correction target transport amount being obtained by correcting, using the correction value, the pre-correction target transport amount for transporting the medium from the third position to the fourth position.
