Scanner Sending Corrupt JPEGs to iMac

I have a Canon Pixma MX522 and an iMac with the latest updated operating system (Yosemite 10.10).


I have used the scanner extensively in the past to scan in photos, but it has been a few months since I did this regularly. When I scan in photos now, using either the Scan Utility program on the computer or hitting the Scan button on the printer itself, the JPEGs that appear in my Downloads are corrupted and cannot be opened.


I've restarted both the printer and the computer a couple of times to ensure that it's not just a temporary glitch. About 1 in 10 photos will scan correctly, the rest show up as corrupted files.


I haven't uninstalled drivers or the Canon utilities programs yet because I'm unsure where to download these files again to reinstall.


Help! What steps can I take to get my scanner back in working order?

Hi amydrobinson,


We can reset the printer system on your Mac, then reinstall the drivers and software for the printer to see if this will resolve the issue.  To do this, please follow these steps:


1.  Choose Apple menu > System Preferences, then click Printers & Scanners.


2.  Hold down the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.  After you reset the printing system, the list of printers in Printers & Scanners preferences should be empty.  If your printer is still listed on the left select your printer and then click the minus (-) button to delete it.


3.  Restart your Mac.


Next, we will want to download the latest drivers from the Canon USA website. Please click here to go to the PIXMA MX522 Drivers and Software page.  Once on the initial download page for your model, please do the following:


1. Verify that the operating system detected in the "OPERATING SYSTEM" drop-down menu is correct, and if it is not, please click the drop-down menu to select your operating system.


2. Next, please click on the red arrow next to the "RECOMMENDED FOR YOU" section and click on the CUPS driver file. When you do, a red DOWNLOAD button will appear. Please click on the checkbox below the DOWNLOAD button, then click the red DOWNLOAD button to begin the download. The time for the download process may vary depending on the speed of your Internet connection and the size of the file being downloaded.


Once you have downloaded and installed the CUPS driver file from the website, please also install all other items from the Recommended for You and Drivers section of the website. To reinstall the software that comes with the printer, please follow the steps above, except for in step 2 you will want to click on the red arrow next to the "SOFTWARE" section instead of the RECOMMENDED FOR YOU section to locate and download the software.

Once all items have been downloaded, please double-click on each of the items on your Mac to install them. If you plan on using the printer wirelessly, please be sure to install the Canon IJ Network Tool last after all other software has been installed; it should be the very last item installed. 


Hope this helps!
