MX710 will print and copy but not scan

[sabedard]

Hi There, 

I have a MX 710 printer that suddely stopped scanning.  It prints ok.  I know the image capture facility works ok as it copies fine.  But for some reason the scan function no longer works.   I suspect something has gone funky with the driver, but reinstalling doesn't seem to work.   Any suggtions?  

Thanks!
