Is SmartWorks MFP and Windows 10 compatible with ColorTrac LF Ci 40?
Yes, all the ColorTrac devices are compatible with Windows 10 according to the release table on the developer's website. I recommend that you check the table to see which version of SmartWorks MFP is required. From what I see, you need the TOUCH version of the software.
