Eventually we got to it. My kids got the old Agfa e25 scanner (year 2000 or something) from their mom ... without a power supply. So, first debugging the power supply, it says it needs 16 Volt 900 mA rectified. Turns out some of these power blocks have their output rectified and some not. I accidentally connected a non rectified version (alternating current) to it ... it didn't work (except for a nice flicker effect on the LED), but also it didn't burn out :-).

Lesson 1: measure the DC and AC voltage of a power block before connecting. For an alternating current power block, the DC voltage reads close to zero (don't try this with 220V, it may blow up your meter if you use low ranges of DC voltages).

Went back to the good old hand-built power supply in the wooden box (some of my friends will remember that from previous offices). Connected that and actually starting at 8 Volts or something the scanner started to give off some lights :-) Cranked it up to 15 Volt and the scanner works great.

Naively, we assumed it would be much easier to install this on a Windows XP box than on Linux ... no way! After trying for like 2 hours to get the the Agfa drivers that are promised to also work on Windows XP I gave up (when inspecting the files, it clearly shows only driver directories for Windows NT, 2000 and Me ... I don't understand how even the official Agfa support site promises these are Windows XP drivers ...).

As a "last attempt", I tried to install the old scanner in Ubuntu? It took me a full 5 minutes to type apt-get install sane sane-tools, find out that the Snape25.bin file needed to be copied in the /usr/share/sane/snapscan/ directory and there we go :-) (that file can be extracted with cabextract from the official Agfa download, that was intended for Windows). And on top, sane has much more features than the limited set of image processing features that where supplied in the free proprietary image processing application that was originally supplied by Agfa with the scanner.

Lesson 2: my naive assumption that commercial devices are easier to install in Windows then in "desktop Linux" can be really trashed now. Desktop linux at least allows one to go to the details and tweak what is required to get it working.

Lesson 3: scanning in full color at 600 DPI gives nice results (and large files: 100 MByte for an A4). The view on the screen is really sharper than the eye can see on the paper.

/me happy camper :-)
