And the nozzle checks are perfect?

My knee jerk reaction is that the sepia ink has separated.  You may have the
older version, and all of them will separate if not regularly used and/or
agitated.

That is probably the problem.

It sounds like your also using a CFS.  If you look at that bottle, you might
be able to see the magenta mostly down at the bottom of the bottle.  The
printer is probably pulling mostly carbon with yellow in it -- and very
little magenta.

You might be able to agitate the sepia bottle to be sure all the pigs are in
suspension.  Then you probably need to pull the agitated ink through the
system, getting the old, separated ink out of the tubes and cart. 

Good luck.
