Manual Adjustment: Adjusting the Misalignment of the Ink Landing Position (Media Gap Adjustment)

This adjusts the landing position of the ink discharged from the print heads. The landing position varies according to the thickness of the media, so we recommend that you make corrections to match the media you are using.

First, print a test pattern, and then determine and enter the correction value. After entering the correction value, print a test pattern again and check the correction results.

This adjustment must be performed in the following cases.

  • When using this machine for the first time

  • When changing the media to use

    • If the test pattern is difficult to see, click UtilityMoveUP or UtilityMoveDOWN next to Move to move the media to a position where it is easier to see.
    • If you want to hold the media to check the test pattern, select Sheet Cutting in the Sheet Cutting window, and then click OK to separate the media.

    The entered correction values are saved.
  8. To check the adjustment results, click Output again.
    The test pattern is printed again.
  9. Check the test pattern to see whether the correction was successful.
    For all the correction values, check that the misalignment is minimized for the two vertical lines indicated by "" (that is, the current correction value). If the misalignment is smaller for another set of vertical lines, set the correction value again.
