Oh, alright.

By your comments here I assume that --papersize is used solely to 
indicate to the ADF the size of the paper that it is supposed to pull 
through, but does not indicate the size of the area that is to be 
scanned.  Is this correct?

I don't really understand the value of the --papersize option, then, 
since the scanner seems to deal with mixed-size and other-size paper 
regardless of what --papersize option I use.  E.g., if I use 
--papersize Letter, then it seems to be quite happy about scanning 
Letter and Legal sized paper mixed in the ADF.

No, I did not set -l -t -x -y.  I had thought (hoped) that my 
--papersize indication would have made those indicators superfluous.  I 
see now that's not the case.
