I was trying to use my scanner on my Canon PIXMA MX492 when I got an error message saying that my scanner software Cannot communicate with the scanner. I usually go to Start – Canon Utilities – IJ Scan Utility.
This opens the little scanning options window but no matter what I tried to get it to work, it kept giving the same error message.
Online research suggested disabling the antivirus and firewall. I tried it and it didn’t work. It’s frustrating when something is working all along and then suddenly it decides not to. Everything else about the printer seems to work.
I’m planning to remove all the drivers and software and reinstall them as soon as I can find my CD or the software online. But I found a workaround that still allows me to use my scanner.
In your search bar type control panel and click on it when it appears on the menu.
In the Control Panel click on Devices and Printers.
Find your printer listed in the window that opens and right-click on it. I noticed right away that this was not the right printer driver originally installed. It should read, Canon MX490 series Printer and not FAX.
I right-click on the printer listed as Canon MX490 series FAX and then on Start scan. This gave me some access to my scanner software, which worked. This is somewhat good news because it seems to indicate a software issue rather than a hardware one.
As I was writing this, I did a quick search on Canon’s website and found the driver software for my printer. So I uninstalled all the old software and drivers. Then I restarted my system. Then reinstalled the Canon drivers and software again. This works.
