I just saw your response above. What model Brother did you buy?And I'm puzzled by your comment about their black & white printer. You don't mean that your new Brother scanner is also a printer? Or did you?
Thanks for the offer of help. It was hard to understand exactly what you were saying, but I tried the "leave the scanner off, reboot the computer, then turn the scanner on" gambit but it didn't work. This is insane. Canon should do a much better job...
