I am not seeing a resolution setting of more than 600dpi when scanning
with a Umax Powerlook ps-2400x from XP. This scanner is a 2400dpi
scanner (hence the model number).

There are some pitfalls when installing this scanner on XP, but I've
documented the correct install routine that worked for me.

Is this also the case when using Sane scanner drivers from linux?

I am using this to archive some -(hundreds), of old 5x7 negatives of
pictures from the Pacific Northwest. (I want to preserve them before
they decay any further(, but 600dpi is hindering the quality of the
scans and is just not archive quality.

Anyone else using this scanner?

I am not familiar with that model, but I do believe that it is a 600 dpi
scanner. The model is ten years old now, and 600 dpi was a lot back
then. All I can find on google now is these two references, both of
which say it is a 600 dpi scanner. The XP number is also excellent
evidence of this.. the scanner reports the limits, and XP shows it.

The 2400 dpi number is just interpolated resampling, not really
useful, and it is NOT the native CCD resolution, which is only 600 dpi
in this case, and is why more is not offered. Model numbers back then
often reflected this interpolated fantasy.

Resolution is used for enlargement, and 5x7 inches is already pretty
big. 600 dpi should be plenty to scan 5x7 inch negatives.
That would allow printing them as 10x14 inches at 300 dpi.
Unless you plan to print wall posters, 600 dpi shouldnt be a issue for
the large negatives.
