For SANE backend purposes these are the same.

Not sure whether this is still an issue, but have you tried specifying a
resolution?  The CX5300 should be able to do 100 but check the output of
scanimage -h for the `--resolution` option for details.

There was a time where the default resolution of 300 wasn't checked
against what the device could actually do.

The out.log file that results from

  SANE_DEBUG_EPSON2=255 scanimage > out.pnm 2> out.log

FWIW, Image Scan! for Linux[1] supports this model just fine.  Click the
All-in-Ones icon and use your browser's find functionality (Ctrl+F ?) to
locate the CX5300.
