I have no personal experience with this scanner but maybe some
generic hints:

scanadf (and scanimage) just scan one image after the other. It's up
to the backend (umax in this case) to make sure that the paper is
moved. If the scanner has a flatbed and an ADF, there is usually an
option called "source" that can be used to select ADF.

xscanimage can only scan one image whith every time you press the scan
button. If that fails, I guess it's a problem with the umax backend.

scanadf:

You haven't enabled the ADF when you used scanadf.

Huh? That looks bad. But I don't think it's related to your problem.


xscanimage:

This time the ADF is enabled.

Looks like it fails right at the start of the scan process. Are you
sure that there is really no hardware/paper problem?

Otherwise I guess the author of the umax backend may know more than me
about that topic :-)
