Thanks Ron for this log, it shows the MF6550 is working as expected.

By the way, this revealed a little weakness in the backend (see the
messages in the log: "Inefficient skip buffer. Should be 75" that I
should have fixed now, with the latest commit I've just pushed. 

So could you update your git files, give another try exactly as you did
this one, and catch another scanimage.log, this one should not contain
this warning message anymore.
