MX870 won't scan

I'm using Windows 10.  I changed my setup from WiFi to wired LAN (due to the fact that I had to keep getting up and cycle the power on and off just to print)  (it did scan before)  and ran the setup program.  The printer prints fine with no problems but when I try to scan I get the following message from Canon MP Navigator but don't see any error codes on printer.

Cannot Communicate with scanner for these reasons:

Scanner is turned off

Scanner is diconnected

It is disconnected from LAN , if using Lan

Please check and try again

Code 5,145,60

Thanks for any help you can give.
