Digital ICE is no longer working on my scanner since I upgraded to macOS 10.15
Perfection V500, V600, V700, V750
Since upgrading to macOS 10.15 the Digital ICE function will cease to work correctly. This is due to the removal of support for 32-bit drivers in this operating system. Whilst other drivers are available for the named scanners they do not feature the Digital ICE functionality.
Please check this article for full compatibility information on macOS.
