    Old Acer/BenQ scanner drivers (x84, x64)

    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 Win7 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: x86.zip
    x64 / 64-bit: x64.zip (replace the INF with this newer one here)
    [2015-09-11] x64 with scan size fix by McReall & newer INF: x64.zip

    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! Simply follow this guide here.

    Some pointers:

    • The tools you need (makecert, Inf2cat, signtool) can be found in the Windows SDK and the Windows Driver Kit. 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 here. 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.

    To scan in Windows 8 after driver installation, simply go to Devices and Printers, right-click your scanner and click Start Scan. You can also use the Metro 'Scan' app, although previewing scans return a very blurry image.

  3. My scanner is not working after the upgrade to Windwos 10.

    Original title : Benq scanner and Windows 10.

    Recently upgraded from XP to Windows 10, and my scanner, Benq model 665-93g will not run.

    So far, I have been unable to find a Driver.

    Found two for WindowsXP and one for Win7. Will that for Win7 work with Win10?

  4. Old Acer/BenQ scanner drivers (x84, x64)

    hello,

    In first, very good work and very good explanation.

    My issue : i use my old acer 640 BU in W10 64bits with your explanation. I use the metro application (and also fax and Scan of Windows). The scan starts. At the end of the page A4, i get an error "Error occure... see documentation of hardware". The preview fonctionnality of "faxAndScan" give the good image. And after that, i teste in my old millenium ( yes i use it for only the scan ) and the scan is good. So i think there is a bug in the dll "acerscad.dll".
    Does someone know how i can resolve this issue?
