It certainly did! This problem may very well be the simplest I've come
across during my adventures in old hardware. As you suggested. The
transport lock was on. That was embarrasing... ;-)

Well I'm happy now and I'm going to take this scanner through its loops
this afternoon, thank you very much!

As for the other OS, well, I use it at work but not at home... Maybe the
Windows driver would have suggested checking the lock, but, thats what a
community is for, right.

Have a nice day,
