Scan quality problem

[Guest]

I have a UMAX S12 scanner running under Windows 2000 pro. It has done
excellent service for years but now the quality of scans has decreased
markedly. When using Magicscan v4.3 (which has worked fine for ages) set to
true colour (32bit) a scan of a colour photo comes out very poorly. There
is no gradation of colours and the colours that turn up in a tiff image are
nothing like the original photo. It looks to my eyes that it is scanning in
some reduced number of colours and making bad guesses about how to represent
the colour range in the original. The monitor is set to true colour and
when I open a previously scanned image it looks as good as ever.

What has gone wrong? How can I fix it?

Check your Display settings on your computer, You may have slipped into a
lower color mode. Make sure you are using 24 bit or 32 bit color.

That can happen if your video is short on ram and you set the display
resolution too high.

Check your color management in the scanner software. The scanner and the
monitor should be using the same color space.
