I know.  From my experience with EPSON devices, there are no easy
rules.  It seems like the various marketing divisions just pick model
names as they see fit.

That is one approach, assuming that there is actually some logic to the
use of "Series".  If I see MF4700 Series, I would sort of expect any
MF47xx or MF470x device to be covered.  I don't know about the Canon
devices, but for EPSON I see stuff like

  - L360 Series
  - L362 Series
  - L364 Series
  - L365 Series
  - L366 Series

at which point I seriously question the meaning of "Series".

I guess the best approach is to simply add whatever model name monikers
are available for a device.  The purpose of our description files is for
our users to be able to find their device.  Whatever makes that task a
bit easier is a Good Thing.

Hope this helps,
