    Description
    This menu item is displayed only when using four-color inks (cyan, magenta, yellow, and black). It sets whether
    efficient ink use or image quality takes priority when youre performing bidirectional printing. Note, however, that
    some high-speed print modes may not be affected by this setting.
    Setting this to DISABLE performs printing with priority given to image quality.
    Setting this to ENABLE lets you use ink more efficiently, although image quality may be slightly coarser.

    Adjusting Head Height to Match Media Thickness
    Procedure
    Press.
    Press
    several times.
    Press.
    Open the front cover.
    Move the lever to adjust the height of the head.
    Moving the lever to HIGH makes a warning beep
    sound twice. Moving it to LOW makes the warning
    beep sound once.
    Close the front cover.
    The print heads return to their original position and
    the screen shown in the figure appears.
    	Press.
    Press
     to go back to the original screen.
    Description
    Depending on the media, media may wrinkle or come loose from the platen during printing, increasing the chance of
    contact with the print heads. When you are using such media, adjust the head height to High.
    Note that the height of the heads cannot be determined by just the thickness of the media.

    Press
    to go back to the original screen.
    Description
    The bidirectional-printing mode (in which the heads perform printing during both their outbound pass and return pass)
    offers the advantage of being able to shorten printing times, but subtle misalignment occurs during the outbound and
    return passes. The procedure to correct this and eliminate misalignment is bidirectional correction. This misalignment
    varies according to the head height and the thickness of the media, so we recommend performing correction to match
    the media youre using.

    Description
    The movement transfer of media experiences subtle changes due to the thickness of the media and the temperature of
    the media heating system. When the movement distance becomes discrepant, horizontal stripes are more likely to
    occur during printing. We recommend performing correction to match the media youre using and the media heating
    system. Also, perform the actual printing in an operating environment identical to that used for the test pattern.

    To make the setting for the correction value even more accurate, we recommend carrying out the following before
    printing the test pattern.
    ➢After loading the media, use
    to feed out the media by about one meter.
     P. 69, Shifting the Print-start Position Forward or Backward
    ➢Set the print-start position near the center of the media.
     P. 69, Shifting the Printing Position to the Left
    Note, however, that you can also make this setting on the computer (by, for example, choosing the media type in the
    software RIP you are using). When you have made the setting on the computer, the computers setting is used and the
    printers setting is ignored.

    Description
    If white or dark-colored stripes appear during printing,you can change the feed-correction value without stopping the
    printing operation in progress.If white horizontal stripes appear,you make the correction value smaller.If dark horizon-
    tal stripes appear,you make the value larger.You can change the correction value regardless of whether settings made
    on the machine or settings made on the computer take precedence.
    A correction value set while printing is in progress is saved only as a setting on the machine.

    When this menu item is set to ENABLE, additional media feed is performed until the trailing edge of the printing area
    is positioned directly on the dryer. The margin between the print-end position and the next print-start position is fixed
    at 200 mm. Any margin setting made on the computer is ignored.
    When this is set to DISABLE, media feed stops simultaneously when printing ends. This means that the trailing edge
    of the printing area is not fed to the dryer unless you continue with a subsequent printing operation.
    When youre using the take-up unit, be sure to set this to DISABLE.
