I am having the same issues. I am using windows 10 and all i want to do is save images and documents in jpeg format and save them to a seperate folder. All images are save as PDF (which I do not want) and is a word file.
I am on the verge of throwing this scanner in the bin. Why oh why is it so complicated to not scan in a jpeg format? The web is full of complaints about this machine. Canon this is a big big mistake and this machine is hopeless.
