Oops!  No I didn't get that right, sorry. I misunderstood the meaning 
of the word "line" I think, or something...yes the head config is out 
of the loop then.

In that case you are correct. Seems funny and you bring up the 
question of whether the tubing has been attacked by the ink for too 
long and so is more permeable than before, or if the ink has just 
evaporated through the tubing and is now sludgy. Or perhaps just old 
after six months. The We-Ink folks once told me that they thought pig 
ink goes bad after six- twelve months, but they may have been trying 
to sell me an alternate product<g>.

I wonder if replacing the k ink bottle, possibly the tubing and even 
more out on a limb, the k cart in the CFS would eliminate your 
problem. Just a wild thought, but with the CFS of course, you can buy 
all the parts seperately, even the glue for the tubing. Anyway, I was 
answering the wrong question before, sorry.
