Software Cannot Communicate with MF731Cdw Scanner

Hello Gals and Guys -

 

I have Canon MF731 Printer/Scanner.  I don't use the scanner much, but today when I tried, the software stated it could not communicate with the scanner.  So far I've unplugged the cable and turn it off/on, but neither of those fixed the issue.  The printer works normally, so is there something I can try to fix the scanner?  Thanks for any help.

Greetings,

What OS and build are you running the printer with?

How is it connected and to what?

Is a specific error code displayed?

Did it ever work correctly (previously)?  

"Unplugged the cable and turned it off", means?  Power cord, ethernet, USB... ?

Thanks Rick.  I appreciate the help.  Whatever you did, it worked because I just tried and it scanned perfectly.  I've had the thing for a while and it always worked, but I don't use it much.  The error said it couldn't connect to the scanner or something akin to that, but as I said, the printer worked normally.  Thanks again.
