SANE is mainly intended as the infrastructure for scanning. The other
tools, with the exception if IScan, all use SANE but provide a more
functional interface.

For example, gscan2pdf that I use supports both single and double sided
ADF and can also scan a bunch of pages twice if your scanner only does
single sided. It provides a number of post scan processing tools and can
save in a variety of formats. But at its heart it uses libsane.

Ok that's good to know. (I have an 8620).

xscan is essentially the gui version of scanimage.
So I had the same trouble with scanimage.  It would only do one page
from the document tray.

I had looked at the xscan docs before but didn't solve the problem.
This time I looked some other docs and looked at the buttons on the gui
and it seems I should have set the number of pages.

Anyway it now works!  The only problem is that the max resolution for
multipage using the ADT is 300 dpi.  Using the flatbed you can go much
higher.

Thank you all, this will prove very useful and will save considerable
time in doing multipage docs.

And xsane depends on sane-backends, so you already have it.

In my case i haven't investigated other tools.

I received many helpful replies, each of which recommend a tool other
than sane.  Is the point that sane can't use the document feeder or just
that you prefer (or simply have used) other tools.

Yes, but Perl packages are tiny.

It's a Perl script, most of what it does is handled by existing modules.
What's wrong with that? If the program did it all itself, it would be
bigger than the dependencies it uses, and they wouldn't be available for
anything else.

It wants to install  49 pkgs  of Perl +  1  more as requirements (grimace).

Why do PDF utilities seem to demand so much external support ?

I use gscan2pdf for that. I've used it to scan hundreds of pages into a
single document, only stopping to top up the document feeder.

Just select them all and use "pdfunite" to combine them.

I am curious do you have the issue where the scanner light returns back 
to the docking area after every page scanned via ADF? it takes so long 
to scan with that problem and it wears down the gears.

I use 'hp-scan' for that:
# hp-scan --adf -m color

It scans all the pages as ppm, then combines it into a single PDF.

It has a bunch of different options, but this is what I start with.

Downside is that the PDF is quite large. I solve that by reconverting the 
images to jpeg.

scanimage has a batch option, but it will save each image in a separate
file. You can walk away for coffee though.
