sane-find-scanner identifies my scanner correctly [probably! =;-)8 ] as Epson Perfection 640U.

scanimage -L says "No scanners were found", so I understand that I have a defective scanner.

It sounds like your scanner is not setup properly in sane. The easiest way for you to do that is to use YAST/YAST2 ("Hardware"-> "Scanner"). Charles

Quite right. But that was easily fixed, and it is now.

Glad that you got it working.

I have found the previously missing "Preview Scan" and "Final Scan" buttons, because they appeared on a detached window that I never saw before.

That pane most likely get detached by accident. By default it is at the bottom left portion of the main window like this: http://linuxreviews.org/kde/kde-user-persp/kooka-scanning.png

Many thanks, Charles.

No problem.

The final scan produced also a generic thumbnail (i.e. having nothing to do with the image). I'm assuming that there is a way to make it generate a real and more useful thumbnail; is there?

Strange, it should show a preview of the scanned image. Just tested it out and it is working. There is something wrong with your KDE setup- are previews showing up in Konqueror or Dolphin? Charles

Konqueror

OK, thumbnailing is working in KDE. Hum, so previews of scanned images are not showing up like the screenshot I just sent you privately? Charles

I want to scan documents and photographs; I have fired up Kooka and read its documentation thoroughly. I find menu choices and icon buttons for doing many things with a scanned image, but so far have not discovered any way to induce the scanner to actually scan anything.

This has to be a failing of mine, because it is not possible that anybody would write documentation for a scanning application without including a sentence in the spirit: "To make a scan, do <thus and so>".

For all I know now, this application is not what I need at all for actually scanning material, but I see nothing in the documentation to tell me what else I need.

If someone will point out to me what I have overlooked this point, I will be very grateful.

I don't use kde and never heard of kooka before, but the very first page of http://kooka.kde.org/doc/manual.php

Says: A) You need sane first, and thus a sane-supported scanner, and provides a link to the sane site. B) How to perform a scan.

As I said in my query (see above), "I have fired up Kooka and read its documentation thoroughly. That led me to check if SANE was installed (thus my earlier query today about a YaST crash when trying to update it unnecessarily). I know from experience that my scanner (Epson 640U) is supported by SANE. Now that I know that my scanner seems not to be functional, It is clear why it did nothing. The fact remains that what I expected to find in the documentation is not there, and that the documentation is much like other KDE documentation I have encountered lately, inexcusably slapdash and deficient. Thank you for the copy of the documentation just below. I wil visit the URL at the bottom of your message. ----quote snipped----

You might need to look at this too: http://en.opensuse.org/YaST_Scanner
