That only required uninstalling and reinstalling the Toolbox software. Download and install the driver that applies to the OS you are using. Used to work fine until now, when I had to replace my HD on my computer (it also doesn't work w/my new netbook, Windows 7 starter 32 bit). Widmer you just saved me from having to buy a new scanner.

Mattia - Sunday, July 4, 2010 3:47:28 PM Thanks Jeff - fixed my cannon 4200F which stopped working (unable to open TWAIN source) One of my recently installed apps. Installed the Canon drivers on my Win 10 Pro system, and I have no problem printing.

Previews fine, scans full res fine, acts like nothing has happened. Thanks, Tibor Tibor - Sunday, October 2, 2011 5:17:50 AM I was unlucky - didn't work - still: many thanks. Again, don't use Toolbox 5.0, it didn't work for me (Win 7 64-bit). Twacker This worked a charm.

Scandall Pro Cannot Find Scanner
I was on the verge of throwing out the scanner and buying a new one. Both programs use Windows Image Aquistition (WIA) but the scanner communicates only through TWAIN. Scandall Pro No Scanner Found Better than some of the other solutions that are out there. Error Sa01020e No Scanner Is Found Like everyone else has experienced, it just stopped working!
Multicore - Tuesday, January 22, 2013 9:32:33 PM I thought I'ld never be able to use my 4400F to scan slides again after upgrading from Windows XP to 7. Worked perfectly on CanoScan LIDE 60 on Windows 7 64 bit os! i've lost two hours installing and uninstalling damn drivers and software :) Seba - Wednesday, September 12, 2012 3:39:02 PM Worked like a charm!! I've used my scanner for years with no problem. Sa01020e Scanner Error

But I gess we can be lucky Canon provides 64 bit drivers for such old products. Rob Callaghan - Tuesday, May 31, 2011 9:22:12 AM Man, you are a lifesaver. Nenad Bulatovic - Thursday, September 12, 2013 9:10:03 AM It's 2013 and I know I should get a new scanner... Nathan - Thursday, November 17, 2011 10:55:17 AM No luck for me, but awesome this has worked for so many people.
This occurred because access rights to the temporary folder that stores the scanned data locally is carried over to the shared folder. larry - Friday, April 5, 2013 8:59:28 PM Thanks so much. Thanks! SHAME ON CANON!
I still don't know how my path variable got erased, but who cares, it's fixed now. JB Leep - Friday, July 29, 2011 5:18:05 PM Thanks for your help!

I think it might have to do with the new 5.0 version - I had been using 4.9 or earlier, I think, with no problems. To reinstall the driver, delete all files and folders that begin with Twain (for example, "Twain_32.dll") in the Windows or Winnt folder.
