Canon MX 922 not scanning -msg: "An error occurred while communicating with the scanner. (-9923)"


Trying to scan on my MacBook Pro with OSX  10.11.2

This has worked with no problem before.  Now I try to get into the scanner through various methods and get the same error:

"An error occurred while communicating with the scanner. (-9923)"


It is printing fine. 


I deleted the drivers, downloaded the most recent drivers and reinstalled.  It still prints fine, but I still get the same error. 


I am at a loss.
