so, determine the beginning and end points where you want the line to be deactivated and then insert a
Dispenser Off command in between those points. When you want the line to be active, insert a Dispenser
On command between those points. An example program and the resulting pattern is shown below.

Fiducial Mark
Click Function
Causes the system to search for the two fiducial marks specified in the No. (number) field of each Fiducial Mark
command. The two fiducial marks are then used by the Fiducial Mark Adjust command to adjust the dispense
program accordingly for any orientation changes between workpieces.
NOTES:
• For the best results, enter Fiducial Mark commands before any dispense or setup commands.
• Two Fiducial Mark commands must be present in a program for the system to perform this adjustment
function correctly.
• A Fiducial Mark is different from a Find Mark. A Find Mark is used only to check the XY position of a workpiece
whereas a Fiducial Mark is used to check the orientation of a workpiece.
• Refer to “About Marks” on page24 for more information on marks.
Fiducial Mark Adjust
Click Function
Double-click
address and
select from
drop-down
menu
Adjusts the program (from one workpiece to another) for any XY orientation changes in workpiece placement.
The system determines orientation correctness by finding two Fiducial Marks. Refer to “Fiducial Mark” on
page106.
NOTES:
• This command is used only in conjunction with a Step & Repeat command.
• Two Fiducial Mark commands must be present in a program for the system to perform this adjustment
function correctly.
• Refer to “About Marks” on page24 for more information on marks.
