Have an iMac running Yosemite 10.10.1 Have just scanned a photo and it has been saved in Documents as a JPEG file - just as I have done many times before. But now when I try to open the file I get a message "The file “IMG_20150103_0001.jpg” could not be opened. It may be damaged or use a file format that Preview doesn’t recognize." JPEG files from earlier scans ) from before I upgraded to Yosemite 10.10.1) however still open.
iMac, OS X Yosemite (10.10.1)
I know this is an old thread, but just found this as I had the same problem. Problem was easily solved by, in my case, going to the Canon website and installing the updated driver for my printer/scanner. Hope that helps somebody!
Are you using Image Capture as the application? I would double check the settings you used when you saved the scan, perhaps the new version that came with Yosemite has different default settings?
Have always used the Cannon scanning software but tried Image Capture. Worked just fine thanks. Now to find the settings on the Canon software which are causing the problem in case the default settings have changed with the Yosemite update
I would try to see if you can get Image Capture to serve your needs. People often have trouble with dedicated 3rd party software for peripherals, and unless you are doing something more than basic scanning, Image Capture will do the job. There's a good chance Image Capture will work for you.
Cannot open scanned JPEG images
