MF654Cdw prints but doesn't scan getting error Can't communicate with the scanner. Error code 600108

I have an MF654Cdw printer/scanner. It is connected to my computer (iMac) by WiFi -- both the printer and computer are connected to the same WiFi. I am able to print. Yesterday, I was able to scan a document and save it to my computer.  Today, the scanner doesn't work. I get a "Cannot communicate with the scanner....Error code 600108." I have turned off both the printer and the computer and turned them back on again. I have verified that the WiFi signal is strong -- the router is 24" from the printer. I have downloaded the scanner driver again. Still no luck. What else can I do?

No-one has any suggestions? How about someone from Canon support? I've had this printer for less than a month and already it isn't working properly.
