M426FDN
Microsoft Windows 10 (64-bit)

While trying to scan using the TWAIN scanning driver I'm getting an error that "The HP LJ M426f427f scan was not found."  This occurs after a fresh install of the latest full solution driver/software package which has included all of the "optional" software/applications in the installer.  This added the scanner to my list of TWAIN scanners but trying to scan presented the error listed above.

 

I've also tried this after installing the HPScanExt utility and it doesn't change the error on the normal scanner and the additional TWAIN scanner that is added to the list fails immidiately.  The WIA scanner for the same device semi-works but lacks the options to actually be all that useful (can't say 2-sided scanning, it doesn't save settings, and trying to scan a multi-page document only gives me the first page).

 

This is while running Windows 10 Pro (64bit) and after updating the firmware on the printer to the version released in March of this year.
