Hello, My Canonscan 4400f driver does not work when I want to scan. I have a MAC OS X 10.6.8 It worked for years. But I emptied my computer and downloaded several times from the internet. But it keeps saying "failed to open a driver" when I push the SCAN button. I hope this is just a common problem. And I hope sincerely that you can help me. Regards, Esther from Amsterdam

Canon only has this scanner driver in OS9 and it will run in classic mode if you are using OSX. This $40 software will work with your scanner in OSX, but for $40 you can purchase an OSX native scanner too.

OK. Here is what you do. (I just did this on an Intel Mac running OX10.5.6)
First go to the cannon site and get the program (File name: deldrvosx1510en.dmg) to uninstall the drivers for your scanner. Also, delete copies of the scan toolbox that you may have installed in your application folder.

Then go back to the canon site for the LiDE 25 and install the drivers (file name: lide25osx11030en.dmg.) This part is very important, in the middle of the install a dialog will popup asking if it is OK to run something like deldvr, DO NOT ALLOW IT TO RUN, HIT CANCEL.
reboot.
Install the canon toolbox software (it should be version 4.9.x not 5.0). File name is : cstbosx4934ej4.dmg
You should now be good to go.
What a %^#%$#-up process on Canons part.

unplug the connections and power supply for a minute or so and plug back in. Make sure you have the latest driver as well.
