5. Dot station (option)
The dot station is used as a dummy board where the dispenser head preapplies adhesive or solder paste,
in order to perform dot feedback and prevent variations in the dispensing dot size which may be caused
by a change in the liquid surface. The dot station can also be used during dispensing work to make the first
application from the head uniform after it has not been in use for a long time. A roll of special paper is used
as the dummy board, which is automatically rolled up. When the dot station is installed to the dispenser
machine prior to shipping, the default setting has already been made.

5.1.2 Entering the pre-dispensing position
To enter the pre-dispensing XY positions on the dot station, proceed as follows.
1
Set the "Dot Datum" parameter.
The dot datum indicates the position at which predispensing starts on the dot station.
1. Select the "Dot Station" in the tree view to display the "Dot Station" and "Position" grids in the main
view.
2. Set the X and Y positions in the "Dot Datum" row.
The pre-dispensing position must be set to a position which is 3mm inward from the right edge of the
paper in the X direction and 5mm inward from the edge of the paper in Y direction.
3. Set the Z position in the “Dot Datum” row.
Check the height where the stopper of Head 1 just contacts the paper on the dot station. Then, as
the Z position, enter a value 0.2 mm greater than that height.
