I get a message like that with my MFC J6710DW from saned on Linux (openSUSE 
12.2). Just installed 12.3 and have not tested scanner there yet. But it 
works fine with XSane, SKanlite and Aquire Images. Also using the brscan-
skey works from command line. You don't say what OS your on but make sure 
you have the correct driver for your unit.
