Epson Perfection 3170, Brother MFC 9470
At home, I have an Epson Perfection 3170. Since I upgraded to Lion, none of the drivers work for me anymore, and the instructions about Lion on the Epson website send me in circles.
I can get a pale, overexposed scan using ImageCapture, then correct it in Photoshop. Very cumbersome.
At my office, I have a Brother MFC 9470, a multifunction laser scanner, printer, copier, and its TWAIN drivers work well. I scan directly into Adobe Acrobat Pro, no problems. That one has a feeder.
I'm frustrated with Epson. Would be interested to hear what models of scanner work well.
