A user with a Fujitsu fi-7160 on a PC with USB 3.0 and 16GB of RAM and DocuWare 6.12 is scanning using DW Scan. We had a issue with the scanner earlier and DW tech support helped us by making sure we had the 32 bit scanner drivers installed. The scanner works, however it takes forever (seriously, like 4 minutes) for a 2 page image to get from the scanner to the DW interface and then another lifetime to upload. Using TWAIN or WIA does not seem to change the performance. Other settings, (auto rotate, delete blank pages, color, greyscale) do not affect the performance either.
Other PCs in the same building with a similar setup do much better, the difference being they are still on Windows 7 whereas the culprit is on Windows 10.
Do the best minds in the room have a consensus about Win 7 and 32 bit drivers performing better than Win 10? I would think it unlikely but it's Windows, so there's that.
