[opensuse] Detected scanner, proper driver, won't scan

The scanner is Epson 640U, in recently installed oS v11.3. YaST > Scanners finds it. scanimage -L and scanimage -T don't. Attemps to scan produce "Failed to start scanner. Invalid argument", which is not very informative. A review of a number of Google hits doesn't add more. I am assuming (hoping) that I have left something undone, but have not found anything to point me to it.
