How can the head gap be adjusted?
Answer: Put in the value directly. * Recommended gap is 1.5mm (.015 inch).
・If the head gap is changed, table height is also changed.
・UJF-3042 is equipped with a function [GAP CHECK].
When ON is selected:
If an obstacle is detected before or during drawing, the table automatically moves down away from the obstacle.
* Because the table continues to move down until the obstacle sensor does not react even though [Head Gap] is set to 1.5mm, the actual head gap may not be 1.5mm. Note that movement of the head gap may cause a degraded drawing quality or ink mist if the obstacle sensor reacts during printing.
When OFF is selected:
If an obstacle is detected before drawing, the message “ERROR505 !WORK High” is displayed and the operation stops.
・UJF-3042 is equipped with a function [WORK SET]
When you check the drawing results etc., you can move the Y-bar.
If the thickness of the media is 100mm or less, it is impossible to adjust the height of the table to 1.5mm (recommended gap). To adjust the height to the recommended gap value, you can raise the table surface using the accompanying vacuum table and the table spacer 50 or 100, according to the thickness of the media.
Use the following vacuum table and the table spacers, according to the thickness of the media.
|Thickness of the media||Required tools|
|100m – 150mm||–|
|50mm – 100mm||Vacuum table + Table spacer 50|
|50mm or less||Vacuum table + Table spacer 100|
For how to set the vacuum table, see ” OPERATION MANUAL” -> “Chapter 2 Basic Operations” -> “Setting media”.
