Ths happens because ScanSuite 11.x.x is installed. This version is not compatible with Dental System versions lower than 2019. In ScanSuite 11 the top light in E-scanners is constantly on when scanning the window is open.

Solution

Uninstall ScanSuite 11.x.x and install the correct version according to the “Lab scanners compatibility matrix with Windows, Dental System and ScanServer (ScanSuite) versions”
