This section explains how to adjust the height of the roll holders and the roll core holders. Firstly adjust the roll holders.

The Adjustment of roll holders and roll core holders can be done in the same way unless the difference is especially described in these procedures.

  1. Make sure that the caster unit is set to the main machine. (Set the caster unit to the deepest position.)
  2. Remove the exterior cover [A] of the holder.
  3. Loosen the screws.
  4. Rotate the three adjustment screws evenly to lower the adjustment position to the lowest. A turn counterclockwise lowers the holder by 0.7 mm (approx. 0.028 inch).
  5. Tighten the loosened screws tightly.
  6. When adjusting the alignment of paper feed side, open the pre-heater cover [A] and secure it with the clamp [B].
  7. Set the roll core [A] to the holder.
    • Paper feed side
    • Roll-up side
  8. Lock the holding lever [A] of the roll holder.
  9. If the media holding lever [A] is lowered, raise the lever.
    • Paper feed side

       

      Make sure that the snap-fits [A] of the clamps face inside of the machine.

    • Roll-up side
  10. Wind the provided film tape around the right edge of the roll core.
    • Paper feed side
    • Roll-up side
      Pass the film tape from right side of the platen, and then wind the film tape around the roll core.
  11. Pass the film tape [A] under the registration roller [B].
    • Paper feed side
      Pass the film tape [A] under the registration roller [B], and then pull it out over the platen.
    • Roll-up side
      Pass the film tape [A] under the registration roller [B] and pull it out from the paper feed side.
  12. Set an edge [A] of the film tape to the position [C] between the two registration idle rollers [B].
  13. Move the film tape so that it is vertical to the roll core.
    [A]: Good (Vertical to the roll core)
    [B]: Not Good (Not vertical to the roll core)
  14. Lower the media holding lever [A] of the front side of the main unit to fix the film tape so that it is parallel to the platen.

  15. Rotate the registration roller [A] by holding the edge of the roller to scratch the film tape.

    • Paper feed side
    • Roll-up side

    When the registration roller is rotated, the registration idle roller scratches the film tape.

  16. Confirm that there is a scratch [A] on the film tape.
  17. Raise the media holding lever.
  18. Slide the film tape [A] to the left side of the roll core.
    • Paper feed side
    • Roll-up side
  19. Set the edge [A] of the non-scratched side of the film tape to the position [C] between the two registration idle rollers [B].
  20. Move the film tape so that it is vertical to the roll core.
    [A]: Good (Vertical to the roll core)
    [B]: Not Good (Not vertical to the roll core)
  21. Lower the media holding lever.
  22. Rotate the registration roller by holding the edge of the roller to scratch the film tape.

  23. Measure the height difference of the left scratch [A] and the right scratch [B] with a scale.

    • If the height distance is within 1 mm (approx. 0.039 inch), adjustment is not required (there is no need to do procedure 24 - 27). Attach the exterior covers of the holder.
    • If the height distance is longer than 1 mm (approx. 0.039 inch), adjust the height.
    • If the height distance is longer than 1 mm (approx. 0.039 inch), proceed to the next step to adjust the height of the holder. One holder whose a scratch on the film is positioned higher than that of the other holder needs to be raised because the scratch at a higher position on the film tape means that the path is longer and its holder is lower.

  24. Loosen the screws of the holder which needs to be adjusted (the holder which has the higher scratch).
  25. Rotate the three adjustment screws evenly to adjust the height. A turn clockwise raises the holder by 0.7 mm (approx. 0.028 inch).
    Check the deviation between the metal plates with a scale and adjust it to be within 1 mm (approx. 0.039 inch).
  26. After adjusting the height, tighten the loosened screws tightly.
  27. Scratch the left and right edge of the film tape again, Confirm that the height difference of the left scratch and the right scratch is 1 mm or less (approx. 0.039 inch or less).
  28. Reattach the exterior covers of the holder.
