The auto correct feature doesn't seem to work on scanned documents.
I often scan documents and save them as .jpg.
Sometimes I scan a document (a bill or invoice or text) that has light text that's barely readable. I use the auto correct feature to darken the text and then save the adjusted document.
What I noticed today was that after I hit auto correct and the text darkens, when I hit save the text goes back the way it was.
Here's the kicker.
That happens with documents that I have scanned with my new Canoscan 9000F Mark II.
When I pull up documents that I scanned with my 5 year old Canoscan 8800F (an earlier generation of the same machine) the auto correct works the way it's supposed to.
Canon tech support is clueless and blames Office Picture Manager, of course.
