Digital BW, The Print

I see that you misunderstood my comments. I did not mean to shred up 
your ideas or belittle you. I try to keep my observations as neutral 
as I can. There was no sarcasm implied in my text. If this does not 
seem to be the case, I apologise. I do ask lots of questions. They are 
meant to be honest ones.

I would like to re-emphasise one idea you have misunderstood: that of 
creating a CFS for only the color cart, since the k ink has the worst 
sludging problems. By doing this and using a simple non-CFS cart for 
the k position (vacuum filled), would it not be possible to avoid many 
of the problems you are now trying to overcome? I thought it might be 
a novel solution to the problem...<shrug>

Looking to when we can have a better dialouge,
Jim H.
