A couple of things to mention:
Auto Crop depends on the paper size selected.

Have done everything you suggested. Did not change anything. Actually I had done those steps 4 times prior. I did figure out the main problem was with store receipts that are mainly 2"wide. However I found if I ignored cropping them, they woud scan properly. hat is not the way it worked prior. I have had this printer since around 2012 and love it. This is the first problem I have had with it other than having to unplug it after 5-6 scans because it quits working. It continues to happen. All Canon support wants to do is sell me a new computer. I did prurchase a new power supply to no avail.
Thnks for your promt respose. You were the only response I gt.
