imageCLASS MF236n issue scanning with feeder

[ryeme]

I have MF236n canon printer / scanner / copier. I can make copies, print with no issues. I can scan one sheet at a time with bed. feeder wont work. when I load i get the beep but when i click to scan i get a mf scan utility message "selected paper size is larger then Physical scanning area cropping will occur." I've tried changing paper size etc 

Using window 10. everything was working for a while. I've already deleted printer, reinstalled
