Question

I have used Image Capture to scan images/documents and then saved them as either PDFs or PNG files.  For some reason, just this past week, Image Capture will no longer save the file.  It scans, and the Scan Results window pops up, but it won't save file.
The file name has no special character in it, just letters and no spaces.
I have done this in the past and it has worked, but now it will not.
I have not upgraded any software, that I am aware of.
After scanning, the Image Capture pops up the Scan Results with the file name in the window, but neither the Scan Results nor the Image Capture window responds to inputs.  The Image Capture window is frozen, with only the "Overview" and "Cancel" buttons active (but non-responsive).
Is this a software issue or a scanner hardware issue?  I am using a HP Photosmart C6200 series printer/scanner on a network using a Time Capsule airport.
Thanks.

I had the same problem.
Got a 90% fix.  Apparently the Mavericks preferences won't work with Yosemite, so I just deleted the Image Capture preferences.
Unfortunately, the "Scan to" folder seems to be permanently set to the Pictures folder.
1.  Quit Image Capture
2.  Go to Finder > Go > Home, which opens up your home folder (named after your user name)
3.  Open Library > Preferences > com.apple.ImageCapture.plist - Drag this file to the Trash
4.  Start "Image Capture", click "Details" and change all your settings as you prefer
5.  Quit and restart "Image Capture".   Notice it remembers all your settings except "Scan to" folder.  It insists on saving to "Pictures".
That's as far as I was successful.  I tried changing the "Scan to" folder to "Desktop", but on launch, Image Capture always sets it back to "Pictures".
This is what I tried:
6.  Download and install "Pref Setter" from http://www.nightproductions.net/prefsetter.html
7.  Quit "Image Capture".  Right-click on "com.apple.ImageCapture.plist" and open with Pref Setter.
8.  Search for "Pictures", which finds "~/Pictures" (the tilde character at the start means your home directory).
9.  Double-click on "~/Pictures" and change it to the folder you prefer.  I like "~/Desktop"
10. Choose File > Save then Quit from Pref Setter.  Note that re-opening the plist file still shows "~/Desktop"
11. Start up "Image Capture" -- on startup, "Image Capture" sets "Scan to" folder to "Pictures"
I consider this a bug.
