2. Setting the Object to be Printed On for the First Time

Load the object and set the printing area and reference point so that printing is enabled.
An overview of the procedure for setting the object is as follows. Follow the instructions displayed on the screen and perform the work in sequence.
  1. Select the object shape type and color, and then enter the dimensions of the object.
  2. Attach so that the center of the object and the rotation axis of the rotary device are aligned.
  3. Set the printing area and printing reference point in order to specify the printing location.
  4. If the object shape type is irregular, measure its ridge line.
Procedure
  1. Select New and tap Next.
  2. Enter a name, tap OK, and then tap Next if the name is correct.

    To make corrections, tap the name you entered.

  3. Select the shape type of the object and tap Next.
    Shape type Description
    Cylindrical A three-dimensional object which can be fully rotated using one side of the rectangle as the axis
    Conical Here, a truncated cone (three-dimensional object that can be fully rotated using the center line of the trapezoid as the axis) and a cone (three-dimensional object that can be fully rotated using one side of the right angle in a right triangle as the axis) are both referred to together as "conical."
    Irregular Here all rotating bodies which are not cylindrical or conical are referred to as "irregular." This is intended for shapes such as a cup with a slightly narrowed end or a bottle with a narrow pouring opening.
  4. Select the opacity of the object and tap Next.
  5. Enter the dimensions of the object.
    Measure the dimensions of the object, and enter the diameter and length. The items to be entered vary depending on the shape type.

    Tap Panel_Icon_Edit_02 for each item to display the entry screen. Enter the value and tap OK.

    Shape type Description
    Cylindrical Enter the diameter [D] and length [L].

    media_size_cylinder
    Conical Enter the diameter of the larger end [D(L)], diameter of the smaller end [D(S)], and length [L].

    media_size_cone
    Irregular Enter the diameter of the larger end [D(L)] and the length [L].

    media_size_other
  6. When entry of the object dimensions is completed, tap Next.
    The support table will move to where the object is loaded.
  7. Open the light shield cover and place the object on the support table.
    When the object has a conical shape or other shape where the diameter is not constant, place it so that the side with the larger diameter is on the right side. If it is placed with the smaller diameter on the right side, printing will not be possible.

    Place the object so that its right edge is a few millimeters to the left of the jig on the right side.

  8. Tap Next.
    The Media Loading Adjustment window appears.
  9. Correctly load the object onto the rotary device.
    • Align the rotational center axis of the rotary device with that of the object to reduce eccentricity.
    • Ensure an appropriate distance between the print surface of the object loaded on the rotary device and the bottom surface of the print head (ink discharge surface).
    • To prevent the object from deforming when held, ensure an appropriate force when the rotary device grips the object.
    1. Tap Load.
      The object has been loaded onto the rotary device.

      If a message indicating the loading failed appears, tap OK to change to the screen for re-entering the dimensions of the object. Redo the procedure from when the dimensions of the object are entered.

    2. To use a sensor to measure the amount of eccentricity, tap Measurement. To check visually, tap Rotate.
      Estimate the amount of adjustment needed for the support table based on the measurement results or visual inspection.

      Make adjustments so that the eccentricity in the measurement results is 1 mm (0.04 in.) or less. The lower the amount of eccentricity, the cleaner the printing results.

      If no adjustment is required, proceed to adjustment of the print surface height (Step (7)).

    3. If the support table needs to be adjusted, press the printer load/unload button to release the object.
    4. Tap the left or right raise/lower buttons (Panel_Icon_UpArrow or Panel_Icon_DownArrow) to adjust the height of the support table.
    5. Tap Load again.
    6. Repeat steps (2) to (5) until the eccentricity during rotation is reduced.
    7. Tap Printing Surface.
      The screen changes to the printing surface height adjustment screen.
    8. If the object is not loaded on the rotary device, tap Load.
      This operation is not necessary if the object to be printed on is already loaded. Proceed to the next step.
    9. Close the light shield cover.
    10. Tap the Table Height raise/lower buttons (Panel_Icon_UpArrow or Panel_Icon_DownArrow) to adjust the height of the print surface.
      Adjust the object so that the print surface extends about 2 mm (0.08 in.) above the top of the light shield cover.
    11. Tap Rotate.
      If the object touches the light shield cover during rotation, or if any part of the print surface goes under the light shield cover, adjust the angle of the rotary device. If adjustment is not necessary, proceed to holding pressure adjustment (Step (15)).
    12. Tap the Rotary Device Angle Adjustment raise/lower buttons (Panel_Icon_UpArrow or Panel_Icon_DownArrow) to adjust the tilt of the rotary device.
    13. Tap Rotate again.
    14. Repeat steps (10) to (13) until the object does not come into contact with the light shield cover during rotation and the printing surface is always above the light shield cover.
    15. Tap Holding Pressure.
      The screen changes to the screen for setting the force with which the rotary device grips the object.
    16. Set the holding pressure.
    17. When adjustment is completed, tap Next.
  10. Perform operations according to the on-screen instructions.
    If this step is not necessary, tap Next without performing any operations.
  11. Close the light shield cover if it is open.
  12. When Irregular is selected for the shape type, tap Measurement on the Ridge Line Measurement screen.
    The undulations of the profile of the object are measured. When the measurement is completed, tap Next.
    When Cylindrical or Conical was selected for the shape type, this procedure is not displayed. Skip it and proceed to the next step.
  13. Set the printing area and reference point.
    The maximum printing area is as follows.

    • 12.5 mm (0.49 in.; []) to the inside from the left and right sides of the irradiation window of the UV-LED device. This area is indicated with .

      RC-300_PrintAria
    • For models with the UV-LED device located in front of the support table:
