The first thing that crossed my mind when I did see the specs of the 
4000 in a Dutch magazine was 'will it use all the KKk inks in matte 
printing'. That Epson didn't think of that concept shows how little 
comes through in R&D from the Epson lurkers on this list. They are on 
the lists as we have seen from time to time when their mailer goes on 
automatic while they are on the beach.

To change to PK and back on the 10000 (MIS 7600 inkset) I can use the 
same method. To spill less ink I have also made a 'sucking cart'. Bag is 
removed from the cart and a tube is attached to the valve instead. The 
head carriage is parked in the middle (cutter change mode) and the power 
cable taken out.  Matte black cart out, sucker one in, ink pumped out 
through that cart into a wine bottle by a small vacuum pump. PK cart in 
(matte chip), vacuum pump at the waste tube side this time + pushing in 
the electric inkline valve and the inkline is filled without loss of any 
other ink. The last filling can be done otherwise too, the 10000 checks 
whether the nozzles actually squirt by using a laser beam and a sensor, 
if there is no black squirted it will pump the head till the black 
comes. The 10000 has three capping stations and three wiper blades, one 
set per two heads so black + cyan (I think) can be pumped separately 
from the rest.
