I had this same question and resulting problem. There is nowhere to get guidance on this... even the people supporting this thread have no answers. I spent almost 3 hours on the phone with QB Support and that also yielded nothing of use... as the scanner I owned (Fujitsu ix500) is not TWAIN driver compatible, even though some places on the internet say it is.
I want to use a typical desktop scanner and don't want to have to use a giant multi-function/all-in-one printer/fax/scanner, and the Fujitsu ones are top of the line, quiet, efficient, and MOST importantly, they can scan Simplex or Duplex (one side or 2 sides) at the click of a button.
I researched this, and found a current model that is TWAIN compatible, the Fujitsu fi-7030. It is about the size of a medium loaf of bread, and folds up when not in use. It's around $500 on Amazon.
It has a nice document loader so you can load everything, even as small as a credit card receipt in the auto-feeder.
It is a straight forward installation, power cord and USB Cable.
When you go to download software, they offer a big piece of software for scanning (Paper Stream)... you DO NOT need that for QB use. You only need the driver from that package called "Paper Stream IP TWAIN".
Then load the "ScanSnap Manager" as well. This puts a controller in your system tray which you can use for routine scanning. You load a doc, then right button click the icon and select Simplex or Duplex, and that's it, it does the rest. It opens a dialog asking where you want to store, send etc. Very easy.
But the best part, is use in Quickbooks. Now when you open the Attachment icon anyplace in QB, look at the top of the bar, and you will see a "Scanner" button. Click that, it opens a QB Scanner Manager. One time, you will have to select the Fujitsu if-7030, and then it defaults there forever.
Click "Scan"... in a few seconds it will ask if you want to scan front side, back side, both sides... select, and then it scans your doc.
It will open a doc and allow you to name and describe the doc, then hit save, and that's it!
The document is named what you want, and placed right on the document in QB.
I hope this helps.
