I had thought this, and tried turning off all power saving. It is also as likely to happen on the first or second image as on later ones, so sleep mode isn't the issue. It usually requires shutting the Scanner off and on to get it to communicate again, so I suspect the scanner. I'll likely try a new one when teh budget permits, but I get along with this one.
