Benq Flatbed Scanner 23 Drivers On XPHave 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 cant 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 didnt find anything. I looked at the DLL in a hex editor, but its not clear where the obviously hard-coded paper format is set. ![]() To scan in Windows 8 after driver installation, simply go to Devices and Printers, right-click your scanner and click Start Scan.

Using a hex editor I located these values at positions 6559 to 655A and 6560 to 6561 btw. F42F to F430 and F429 to F42A in the acerscad.dll file of size 108 032 bytes. Notice that numbers referring to the paper dimensions are in very close positions, which makes us guess they are not a piece of instruction in the code, but really the paper dimensions.
