It (iscan) doesn't upload firmware for the CX7400.  Moreover, firmware
uploads would be lost when you power-down the device (long enough).

I'm curious as to how you installed and removed iscan.  My current
best bet is that the epkowa backend is still found in a place where
SANE finds it, typically in /usr/lib/sane/, and epkowa.conf is still
on the system as well.

If you installed with `rpm -U` and removed with `rpm -e` everything
ought to be gone after removal.  Maybe you're using a less common, as
in one we don't test with, distribution and things didn't go as they
were intended to.

Let me know what distribution you're using and how you installed and
removed iscan.  Were there any messages by any chance?  Also, what
device names do you get with `scanimage -L`?  If there's any that
start with 'epkowa:' the backend's still there somewhere.

Hope this helps,
