1. A: Determine the positions of the media.

This section describes how to use the suction fan to prevent media skewing.

Because the suction fan does not operate, the following procedure cannot be used to load media when using transparent media or media with high reflectance whose edges cannot be detected, or when Disable is set for Preferences - Media Edge Detection. In these cases, refer to 1. B: Determining the Positions of Media (If Media Edge Detection: Disable).

By default, Skewing Correction Support at Setup is set to Enable.

MEMO
Perform a printing test for adjustment in 5. Configure settings to match the media.. Load media which can secure the printing area for the printing test. The printing test width is the following.
  • Simple Correction (Auto): Approx. 290 mm (11.42 in.)
  • Detailed Correction (Manual): Approx. 375 mm (14.76 in.)
Procedure
  1. Tap the operation panel.

    ON
  2. When instructions appear on the screen, tap Panel_Icon_ONOFF on the operation panel.
    The machine sub power is switched on.
  3. Set the Skewing Correction Support at Setup.
    1. Tap Panel_Icon_Menu.
    2. Tap Preferences - Skewing Correction Support at Setup.
    3. Select Enable and tap Save.
    4. Press Panel_Icon_Home to return to the home screen.
  4. Open the front cover.
  5. Move the media clamps to the outside of the grit rollers on the left and right edges respectively.

  6. Move to the rear of the printer. Release the locking mechanisms of the media holders, and then draw them to the left and right ends respectively.
    Unfasten the media holder
  7. Determine the left and right positions of the media with the grit patterns used as the reference.
    Note the following points when determining the positions.
    • Ensure that the left edge of the media is positioned so that it is within the range of the grit pattern of the left edge.
    • Ensure that the right edge of the media is positioned so that it is within the range of one of the grit patterns.

  8. From the rear of the printer, pass the leading edge of the media between the pinch rollers () and the grit rollers ().

    You will hear a beep. Approximately 5 seconds later, you will hear two beeps, and then the suction fan will activate. While this fan is operating, the media will not move backward even if you remove your hands from it.

    When loading the media from the front of the printer, feed the leading edge of the media (the side where printing will start) over the platen, and then pull the media to the front to activate the suction fan.

  9. (Move to the front of the printer.) Make sure both edges of the media are above the grit rollers.
    Be sure to place the right edge of the media on the right-end grit roller.
    Go to the front of the printer and make sure you are following the guidelines
  10. Move the left and right pinch rollers, placing them on both edges of the media.
    Position them approximately 10 mm (0.39 in.) from each edge of the media.

    IMPORTANT
    • Be sure to use the left and right pinch rollers. The force with which the media is pinched varies between the middle pinch rollers and the left and right pinch rollers. Using the middle pinch rollers to pinch the media edges will lead to unstable media feeding.
    • If you want to readjust the media position before securing it in place, redo the procedure from step 7.
    MEMO To smoothly move the pinch rollers, push down close to the rail.
  11. Move the middle pinch rollers (B) over all the remaining grit rollers (A) covered by the media.
    There are grit patterns (C) wherever there are grit rollers.

    IMPORTANT
    • Place the middle pinch rollers over all the grit patterns within the media width. If you have forgotten to place the middle pinch rollers, the media will be skewed during printing or will come loose, which will have an effect on the printing quality.
    • The middle pinch roller will not lower onto the three grit rollers from the right end. Place the middle pinch roller on a grit roller other than these three.

    • There may be extra middle pinch rollers depending on the width of the media being used. Move the extra middle pinch rollers to positions where no grit patterns are present. Where no grit patterns are present, the middle pinch rollers will not come down.

  12. Lower the loading lever (front).
    The media is held in place.

    Lower the low binding (front side)
    IMPORTANT If you want to readjust the media position before securing it in place, redo the procedure from step 7.
  13. Line up the edges of the media with the centers of the holes of the left and right media clamps.

    IMPORTANT

    Be sure to use the media clamps when you set up media.

    If you load the media clamps directly before printing after the media setup is complete, the machine may print on the media clamps.

  14. Close the front cover.
