"additionally you might try to acquire a scan at a different resolution
via scanimage"

Sorry to be so slow responding, but I am allergic to terminal & so
Scanimage has been a difficult experience...

I did eventually get scanimage to produce its default image, using:
"chris@Acer-desk:~$ scanimage >scan-file.pnm"
This image was 26MB - the same size as iScan / 300dpi / color document / .pnm.

Much later, after many failed attempts, I think I discovered the right command for 150dpi, with this result, showing that scanimage uses the nearest "default" resolution:
"chris@Acer-desk:~$ scanimage --r 150 >scan-file2.pnm
scanimage: rounded value of resolution from 150 to 300"

That produced another 26MB image, but terminal never came back to a prompt.
When I tried to close terminal, I got a warning that a process was still running & I had to kill it to exit, which I did.
After that, the scanner could not be stopped on the button until the next reboot & no scanning was possible with any program as the scanner was "busy" or whatever.

Now, even after cold reboots & even after only a basic "$ scanimage
>scan-file.pnm" scanimage never gets back to a terminla prompt & I have
to kill process to exit terminal every time!

Next, I went to see how it worked in Ubuntu 10.04LTS which multiboots on the same PC & Scanner & where I have never tried scanimage.
I simply tried "$ scanimage >scan-file.pnm" which produced a 25MB image as expected but, surprisingly for me, failed to return to a prompt & forced me to kill process to exit terminal...
This sounds as though I have now screwed up something inside the scanner, doesn't it?

Fortunately, iScan & Simple Scan & XSane seem unaffected as long as I
don't use scanimage.

So I suppose I try sane-devel now...

Title:
  Resolution control not working

Status in Simple Scan:
  Triaged

Bug description:
  Details in my Ubuntu Forum thread:

  "Firstly - congratulations for Simple Scan, which lives up to its name admirably!
  Xsane is no doubt wonderfully competent, but far too complicated for casual use.
  But I am having a problem with Simple Scan, in that I can't seem to get selected resolutions to have any effect.
  A typical A4 mainly-text document I am playing with, ends up as:
  165K when scanned & saved as text pdf at 75/150/300 or 600dpi...
  1.5MB when scanned & saved as text jpg at 75-600dpi
  2.2MB when scanned & saved as photo pdf or jpg at 75-600dpi.
  My Epson V200 scanner allows normal resolution selection with Xsane or with Epson's iscan application.
  Thanks for any suggestions!" - unquote.

  I started that thread in December 2010 & still have the same problem today.
  As a summary - the resolution control has absolutely no effect on the results.
  No error messages (unless I try 2400dpi) & nothing in simple-scan --debug >simple-scan.log
  I now have Simple Scan 2.32.0.1-0Ubuntu2 in Ubuntu 11.04.
  The scanner is an Epson Perfection V200 Photo & has normal resolution selection in XSane & Iscan.
  Thanks!
