I have been running Ubuntu 8.04 for over a month now. I installed my Samsung SCX-4200 and have been scanning with it using XSANE as admin. I could create multipage docs, etc. with no problems. Today out of nowhere after scanning one page I get an error in XSANE that says "Error starting scanner: device busy." On the scanner the scanning element is stuck at the end of the document and I have to turn the scanner off and on to reset it. If I scan from within the Samsung Driver scanner properties it works fine and I can scan as many pages as I want (but cannot create PDFs as I scan in XSANE). I have tried reinstalling XSANE and related packages but nothing seems to fix the problem. Any ideas or fix would be greatly appreciated.
