Hi Martin,
Might not be relevant, but...
We are having a similar problem, with one patch on a TC3 chart
consistently being out by over 10dE, and us not managing to pull it
back in.
patch is C=10, M=80, Y=65, K=0. So not pure Cyan like your problem...
Also, this is on 9800 ...
Not sure if this is coincidence.. or dodgy Epson batches..
This has only happened in the last week.

We've noticed changes to the Cyan ink that we use on our Epson 9600s.
Two batches of the T5442 ink cartridges marked as:
03.2009 - 011A
10.2009 - 151A
Seem significantly different from the Cyan that we have been using
for the last 3 years.
I haven't got any samples of the previous colours to measure and
compare, but have been alerted to the difference because our FOGRA
proofs jumped from ~1dE to greater than 8dE in the 100% Cyan patch
and we are having real problems getting this back under 3dE.
Has anybody else noticed anything odd with Ultrachrome Cyan?
