Digital BW, The Print

I've been trying to get this to work and haven't gotten any help from
Lyson...too busy with a corporate merger to bother with customers,
perhaps?  This has been going on for nearly 3 months as I gave up and
waited for them to respond for too long, but that guy got fired....

Anyone have any experience with it?

I'm using an Epson 2000P, two of them in fact as I want to dedicate
one to black and white only and improve on BO with Epson inks if
possible (right now I doubt it...), and have had the same problem with
both.  Both work beautifully with Epson inks...so it's not the
printer, heads, or the like.  Also get perfect nozzle checks, target
prints, etc.

Here's the issue.  I get a strong blue cast when printing.  If I
reduce the end point for the blue ink, the color cast is reduced. 
Turn it off and I get a very poor warm print, blue is, of course,
gone.  Reduce it to a low level, just a bit of blue.

When I use the profiles supplied the problem is the same.  When I
built my own profile for Museo Silver Rag, same problem, especially in
the light shadows.

It appears to me that there is a blue ink in the third position in my
cartridges where there should be a very lt. grey, which appears to be
in the 5th position.  Is this possible?  Studying the graphs of ink
outputs in Profile Creator, it appears that the third ink should be
putting down a nice lt grey, added to with the second and finished
with the pure black.  But there's blue instead.

Anyone have any information on this kind of problem?  My guess is
defective color cartridges but I don't know.
