Readjusting Height during Printing

This setting allows the height to be readjusted to continue printing even when the object comes into contact with the head gap sensor in the following cases.
  • When the object becomes loose or warps during printing
  • When the print surface is raised due to printing on stacked objects

This function is effective when using objects that cannot be reprinted on.

However, this setting has the following disadvantages.
  • Printing time is longer because of the time required for readjustment.
  • The print surface comes into contact with the head gap sensor.

Therefore, Readjust should be used for printing for which you want to ensure image quality even if it takes longer or printing that cannot be redone.

MEMO
  • When the height is readjusted automatically and printing continues, the height setting is changed. Therefore, the print quality may be changed. Hence, proper printing requires that the object to be printed on be secured properly before printing to keep it from moving out of position or lifting up.
  • Select Readjust to automatically adjust the height when the head gap sensor touches the object.
  • Even if Readjust is selected, printing and setup will be canceled in the following cases.
    • When the height reaches the Maximum Value (Threshold) of automatic adjustment
    • When the object to be printed on comes into contact with the head gap sensor during automatic readjustment, even if the flat table has moved to the bottom
  • If this function is not used (Operation on Height Error Detection:Stop), printing is stopped when a height error is detected during printing, and Flat Table Height Error is displayed.
Procedure
  1. On the Utility home screen, click BN2_Utility_Icon_MENU.
  2. Click Preferences.
  3. Select Readjust for Operation on Height Error Detection under Clearance Settings.
  4. Click [▲][▼] next to Maximum Value (Threshold) to set the maximum amount by which the flat table is lowered when a height error is detected.
    The height adjustment is made gradually until the object no longer touches the head gap sensor. Set this in anticipation of height variations, such as when there are changes in the height of the object.
    MEMO
    The greater the distance between the print surface and the print heads, the lower the print quality tends to be. It is preferable to make smaller adjustments. Keep the following points in mind when determining the Maximum Value (Threshold).
    • Consider the effect on the printing image quality in order to obtain satisfactory image quality.
    • The variation in height across the entire print surface (not the print target area but including parts that will not be printed)
  5. Click Apply to confirm your entry.
  6. Click Close to return to the original screen.
