How to Improve the Accuracy of Mark Searches
If there are many areas on a workpiece that resemble a mark you saved, you can use the Area function of the
Template Match window to fine-tune how the camera evaluates these areas against the saved mark image. Doing
so increases the find-mark accuracy of the system.
NOTE: Advanced features for manipulating saved mark images to allow the system to find them faster and more
accurately are available in the optional OptiSure software add-on. Refer to “OptiSure Software Key” on page93
for the OptiSure kit part number. Refer to the OptiSure manual for operating instructions.
PREREQUISITES
The system is in the CCD Mode.
The mark you want to fine-tune is saved in the Mark Library.

How to Use Marks or Fiducial Marks in a Program
Use the Mark command in a program as follows:
• To confirm the presence or absence of a workpiece.
• To confirm that the correct workpiece is present.
• To check the XY position of a workpiece.
Use two Fiducial Marks in a program as follows:
• To move the dispensing tip to a specific target area on the workpiece.
• To check the XY orientation of a workpiece. The system automatically adjusts the program to compensate for
any changes in orientation.
PREREQUISITES
The system is properly set up. Refer to “Setting Up and Calibrating the System (Required)” on page45.
The system is in the CCD Mode.

How to Use Marks to Dispense onto a Plain Workpiece
The Edge Adjust command is needed when you must create a dispense program for a workpiece that presents one
of the following challenges:
• Very large, rounded corners
• No obvious features for creating a mark image
PREREQUISITES
The system is properly set up. Refer to “Setting Up and Calibrating the System (Required)” on page45.
The system is in the CCD Mode.
To learn how to use this feature, draw a black rectangle with very round corners on a sheet of white paper and
use it as a template.
Overview for Dispensing onto Featureless Workpieces
The following tasks are required to create a program for dispensing onto very plain workpieces:
• Creating and saving mark images on two edges of a rectangular area. For each mark, you will need to enter
Width and Height values.
• Setting up the search range for each mark.
• Correctly using the Find Mark and Edge Adjust commands in the dispense program.
