The fujitsu machines with epson chipsets look kinda similar, their
read-heads are made in multiple pieces, with weird overlaps, and
padding between the color planes, so it can look like total garbage at
first. can you scan something small in color and post that on the web
too? (and the image as produced by the windows software too)
