Sorry. The ESC m command I mentioned was in message 19 of that bug report and I didn't notice the log after that. > So looks like there's something else going on? Let's give this[1] another look. OK, so it doesn't like the area setting (ESC A). The Perfection 640 is one of the scanners that requires "color shuffling". This implies some additional logic in the scan area calculations. Since my previous post[2], I've looked a little at the color shuffling logic in the epson2 backend but cannot easily determine whether what's going on there is correct. I'd suggest people use the epkowa backend, available from my employer's website[3].
