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.

1. Max Amount
Divide the total dispense consumption (equivalent to one whole syringe) measured during automatic operation by 1000,
and enter the result in "Max Amount". This parameter is used to issue a warning when the dispensing liquid has run out.
(Max. 99999.99)
For instance, enter "1357.46" if the total dispense consumption is "1357456".
When this value is reached, the warning buzzer will sound and a message will appear. If the machine has the optional
adhesive run-out sensor or if you are not going to use this function, enter "0".
2. Feedback Condition
Enter the number of boards for which recognition feedback is to be performed.
After dispense is completed for the specified number of boards, dot recognition correction will be performed on the next
board according to the predispensing data. (Max. 9999)
