This is just a FYI as I had just managed to get my own Acer 320U scanner up and running in Win8.1 x64. This driver also works in to Win10! The same drivers work for the following abandoned Acer/BenQ scanner models: • 310U/620U • 320U/340U/620U+/640U • 620UT+/640UT • 1240UT/5100U • 640BT/640BU • 4300U/3300U • 4300U/3300U x86 / 32-bit: x64 / 64-bit: (replace the INF with ) [2015-09-11] x64 with scan size fix by & newer INF: All drivers are unsigned and this poses a problem if you are using x64 as you will either need to completely disable the driver signing check or sign the x64 drivers yourself. I recommend the latter as it's actually quite easy!

Some pointers: • The tools you need (makecert, Inf2cat, signtool) can be found in the and the. You don't need to install everything! Just check the 'Tools' in both the web installers will do. • If you cannot download the SDKs due to filesize (~2.2GB), I zipped the 3 tools and you can download them.

But please download from Microsoft whenever possible. • When making your own cert using makecert, add the -pe parameter so that you can export the private key of the certificate later (useful for installing your own signed drivers again on a different PC in the future! To export, simply right-click your certificate in the MMC snap-in) • You need to use the newer INF in the Pastebin as the old one will not sign or validate correctly.

Thank you so much for this post. I got the scanner to work on Windows 7, 64 bit.

Have you noticed that with this driver the scanner will only scan 'US letter' format (11' x 8.5')? A4 is about 11.7', so due to this glitch in the driver, the scanner has become worthless, since I can't scan a full page A4 any more (which worked with previous drivers on XP and W7, 32 bit).

I tried to find an updated version of AcerScad.dll, which is the DLL providing the WIA interface for Windows, but didn't find anything. I looked at the DLL in a hex editor, but it's not clear where the obviously hard-coded paper format is set. Thank you so much for this post.
