A: Determine the positions of the media.

This section describes how to use the suction fan to prevent media skewing. When using transparent media, whose edges cannot be detected, and when Preferences - Media Edge Detection is set to Disable, the suction fan does not activate, so media cannot be loaded with this procedure. In these cases, refer to 2. B: Determine the positions of the media (Media Edge Detection: Disable)..

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

Procedure
  1. 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.
    • Hold the media holders from the outside and move them.
    • 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.

    CAUTION

    Do not hold places other than those instructed. Do not move the media by holding it directly.

    Otherwise the media may fall off the media holder and cause injury.

    IMPORTANT

    Firmly decide the left and right side positions of the media at this point.

    After this procedure is completed, if the left and right side positions do not fit the proper positions when securing the media with pinch rollers, you will have to go back to this step to redo this procedure. If you just hold the media to readjust its position forcibly, the media will be skewed during printing, which will have an adverse effect on the printing results.

  2. Secure the media holders.

  3. Use the following procedure to load the media.
    Doing so will prevent media skewing.
    1. Pass the leading edge of the media between the pinch rollers (A) and the grit rollers (B).

    2. Feed the media until you hear a beep, and then additionally feed approximately 20 cm (7.87 in.) of the media.
      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 position of the media will be maintained even if you remove your hands from it.
    3. Hold the media holder flange, turning it in the take-up direction to eliminate the slack in the media.

    4. Once the media is taut, additionally take up approximately 10 cm (3.94 in.) of media.

      MEMO If you take up too much media, you will hear two short beeps and the suction fan will stop. Take up the media, and then redo the procedure from step (1).
  4. (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.

  5. 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, return to the back of the printer, release the media holders, and then redo the procedure from step 1. If you just stand at the front of the printer and hold the media to readjust its position forcibly, the media will be skewed during printing or will come loose, which will affect the printing quality.
    MEMO To smoothly move the pinch rollers, push down close to the rail.
  6. 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.

  7. Lower the loading lever (front).

    IMPORTANT If you want to readjust the media position, return to the back of the printer, release the media holders, and then redo the procedure from step 1. If you just stand at the front of the printer and hold the media to readjust its position forcibly, the media will be skewed during printing or will come loose, which will affect the printing quality.
  8. Line up the edges of the media with the centers of the holes of the left and right media clamps.

  9. Close the front cover.
