Fujitsu ScanSnap S300 PfussMon has stopped working

I am using Vista 32 on a Dell XPS. I tried to install a new Fujitsu ScanSnap S300 which uses proprietary drivers rather than TWAIN or ISIS. While it installed, whenever I tried to access I got the error message: FuSSMon has stopped working. Software I have on this computer includes Norton 360 and Tweak VI. I spent hours with Fujitsu tech support and they even took over the computer. Of course we did the usual Uninstall and reinstall using FTP programs. I do not see this problem discussed online which makes me think it is some conflict on my machine. I have never had a problem before with any installation. My Epson flat bad scanner works with TWAIN. Any thoughts?

    I'm right there with you - Fujitsu Scanner (S510) and a Dell Dimension E520 running VISTA. I'd love to know if by now you have found a fix.

    Any solutions with this problem
    I was told by fujitsu to reformat and relaod my vista; kind of overkill

    I've had this issue too.  They told me it's a known driver conflict with Dell laptops with video cameras.  I was told to remove my camera driver to make it work, though it still didn't.   Removing my camera isn't a long term option!

Find your specific scansnap product and update it:

A user had a similar issue and I found this update for the scansnap S1500 manager:

This occurs with certain Intel dual core processors, so you might be effected accordingly.

Fujitsu has to send you 3 files to replace, keep trying the help line until you get a live person; they will email them to you. call 1-800-626-4686. This problem is not specific to Dell, happens on Compaq too.

My ScanSnap has worked flawlessly for years. I just tried to scan and got the following message: undefined error occurred.(0xffffdcf7) Won't scan. Tried to reboot - no luck. Let me know...

The same thing happened to me. In a nutshell, you have to install new drivers. Have you recently upgraded your system to SnowLeopard or Lion? I did, and that's what went wrong.

To do:
1. Make sure you have the latest ScanSnap manager:
Install that.
2. Get the Lion update:
Install that.
3. Open the new ScanSnap Manager (v 2.2). Delete the old one from your dock, so you don't get confused.
4. Scan away.

My ScanSnap S510M stopped working. There is an error code "0xffffdcf7" . I tried rebooting but it still does not work.

I had a similar problem. My problem may be related to installing a second scanner (Canon MG8100). Reinstalling the ScanSnap driver solved my problem.
