To scan locators or dies separately instead of all at the same time:
In the Locator list or the Die list on the Indicate locators/dies page of the scan wizard, select the locators or the dies that will be scanned in this phase and click Next.
The selected locators/dies will be scanned. Check the position of the scanned locators/dies.
Click Scan next locators set or Scan next dies set. You will return to the Indicate locators or the Indicate dies wizard page. The locators/dies that have already been scanned, will be shown in green in the Locator list or the Die list. Select the locators/dies you want to scan now, and click Next. Repeat this step until all locators/dies have been scanned. If multiple locators are detected on the same location, an error message is shown.
Note
In case of problems, try to rescan all the locators/dies in a different order. On the Indicate locators/dies page, click Rescan all locators/dies and recommence.
