OK, I *think* that I might be seeing something like what you are.
I get no stripiness, but some resolutions give me a red tinted scan.
It looks to be the same kind of pink tint that you see but it is for the
entire scan area.

I have to say that I only get this if I set the bit depth to 14. 8
doesn't give me any problems.

In all cases, I get the funny thin yellow stripe on the right hand side
which may or may not be related.
For all the scans, I am using xsane.

I will look into this over the next few days. It gives me something to
look at, at least.

Cheers,
Ralph
