Haven't used the scanner in a month or so and when I recently try to run preview or scan I get 'The autofocus operation has failed' and if I continue running the scan I get a blank white page. Anyone come across this problem?

If you continue to get this kind of error after restarting the computer, you may need to update the scanner's device drivers or reinstall the included software. You should also make sure only one program or application is attempting to use the scanner by closing all but the one program you are trying use with the scanner. One last note - always either let the program you are scanning to operate the scanner or let the scanner invoke its default application by pressing the scan, fax or copy buttons on the scanner. Do not for instance try and scan an image into a running program that initiates the scanning process itself while also invoking a scan from the scanner's control panel. The two operations will conflict.
Nice camera, and I've had similar problems before.
What's more typical than anything else, is the gearing for moving the lens gets misaligned or jammed. This can happen with foreign object getting in, like fine sand particles, or the lens being jarred or bumped during operation.
For a camera like this, I would not recommend trying to fix it yourself, because you can end up doing more harm than good. A trained tech can often clean it out and repair the problem fairly quickly, to get you back to using it.
Attempting to use it in this condition could potentially make the problem worse, depending on the cause.
This lens lacks the autofocus motor, so it will only autofocus on cameras with the motor. This lens will autofocus on every Nikon digital SLR except for the D40, D40x, D60, D3000, D3100, D5000, and D5100. It will autofocus with the D1 family, D2 family, D3 family, D50, D70, D70s, D80, D90, D100, D200, D300, D300s, and D700 (I hope I haven't left any out).
The shutter assembly has failed, a common fault with all older autofocus SLR's. it's nothing to do with the autofocus itself, just that AF SLR's usually tend to have fully electronically operated shutters which cannot be serviced and repaired like older models.
The only fix is to replace it, but it's no longer available and even if you do find one the repair is not economically worthwhile.
If you're not too choosy as to the brand, then free similar SLR models complete with lenses are regularly available on FreeCycle and Freegle. It's where I got all of mine.
Make sure you didn't change the default settings for the scanned image. Sometimes we fiddle with those settings and create a file size that is either too large or out of bounds for our scanner. also try reducing the scanned image density and see if that helps. Sometimes the image is just too large for your installed memory to handle, I saw a jpg image on a customers PC once that was 8 gigabytes and he complained that it would never load.
DS Dual 4 even works with SnowLeopard on a CoreDuo MBP. But it doesn not support Autofocus when used under USB2. You have to use a USB1.1 Port, if you want to use autofocus function.
Every time the software crashes, because you tried e.g. to use autofocus with USB2, you will have to close the application, go to the folder User/Library/Preferences/DS Dual4/... and look whether there is a file name something like "MFSlib...." and pull it to the trash bin. You can start the application again.
PS.: Your keyboard USB port is a USB 1.1 port!
Hi there I had the same problem with auto focus sf-210.
If tried many things to correct the problem and what I found was that if you you put a small book halfway on the opposite site of the power button then I have maybe 1 or to slides out of focus and the other 35 slides are perfect ! (I used it with HAMA slides other slides I didn't test )
sounds like a proprietary TWAIN driver from Canon must be installed...try forcing driver from cd under current devices driver...under device manager, look for imaging devices, then right click-properties then driver-update driver...make sure cd is in
