A fixed focus scanner would likely be such because it has a very wide
DOF.  These scanners, in general, use a long optical path, allowing for
a more DOF, but sometimes this design has other problems.  As film
scanners have heightened their resolution, ability to focus has been
incorporated because even fixed focus has its limits which might have
been less obvious when resolution wasn't as high.
