A small comment regarding scanning &quot;all pages&quot; when scanning from ADF...
<BR>
<P>I agree that for the vast majority of scanning applications, scanning until
<BR>
the ADF is empty is exactly what the user wants. However, there are common
<BR>
variations...
<BR>
<P>In the production scanning world, group of pages to be scanned are sometimes
<BR>
interspersed with separator pages on which information about what to do with
<BR>
the group of pages is encoded. The scanners can actually decode the
<BR>
separators and process the group accordingly.
<BR>
<P>Sorry if this adds more heat to the fire...
<BR>

<P><P>Hi,
<BR>
<P>&nbsp;&nbsp;&nbsp;sorry if by asking a few simple questions I have revived some old
<BR>
feuds :-) I'm new to this list and don't know much about the personal,
<BR>
or &quot;cultural&quot;, side of the SANE project but it seems quite, errr,
<BR>
interesting...
<BR>
<P>I'll tell you what my view is on this. Call it the &quot;user's
<BR>
perspective&quot;. I bought a scanner with ADF and duplex specifically
<BR>
because I want to scan a large amount of stuff automatically.
<BR>
<P>I don't care for graphical front-ends because they usually involve
<BR>
something called &quot;mouse&quot; which tends to be difficult to automate.
<BR>
<P>I want to put a stack of documents in the scanner, hit a button
<BR>
(preferrably on the scanner, not the computer), have a cup of tea and
<BR>
later find a bunch of files, neatly named &quot;2001-03-01-doc1234-p2.tif&quot;
<BR>
or such, in a directory created for that purpose. (Ideally, I'd also
<BR>
like the same file as .txt with a bit of auto-OCR thrown in but that's
<BR>
not the scope of SANE - unfortunately.)
<BR>
<P>This is, of course, worlds away from the kind of scanning done on a
<BR>
flatbed (or rotating drum) scanner by hobbyists or professionals,
<BR>
where individual objects of different sizes are scanned, previews are
<BR>
taken, windows defined, parameters tweaked, and so on. I just want the
<BR>
stuff on my hard disk, and I might invest some time to find the best
<BR>
settings but afterwards I want it to go through 1,000 pages without
<BR>
fuss. (Yes, I know, my ADF only holds 50 pages but I didn't have the
<BR>
money for the industrial version...)
<BR>
<P>If, every once in a while, I want to scan something using a graphical
<BR>
front-end, I will probably just insert one single sheet into the ADF.
<BR>
If the front-end, after scanning that one page, pops up a message
<BR>
saying &quot;ADF out of documents&quot;, that's not nice but not a big deal
<BR>
either.
<BR>
<P><EM>&gt; Well, I never understood, why ADF should mean: &quot;scan all documents&quot;.
</EM><BR>
<EM>&gt; (even if it might be useful in some/most situations) There might be
</EM><BR>
<EM>&gt; persons that put 50 documents in there doc feeder and then just want
</EM><BR>
<EM>&gt; to scan 5 or 10, do something with the scans and then scan the next
</EM><BR>
<EM>&gt; 5 or 10.
</EM><BR>
<P>This is - pardon the expression - bullshit. Of course you're right
<BR>
&quot;theoretically&quot;, but - in my humble opintion - these &quot;theoretically
<BR>
right&quot; things are exactly those that keep people from developing
<BR>
practical applications. As I said, I got the ADF to scan a lot, and to
<BR>
be honest I would prefer to define the amount of pages to be scanned
<BR>
by inserting exactly that amount into the ADF, instead of having to
<BR>
use a mouse/keyboard/whatever to tell some piece of software that,
<BR>
yes, I have put 50 documents in the scanner but would it please, for
<BR>
now, just scan the first 3 of it...
<BR>
<P>Just my 2 cents,
<BR>
Frederik
