Thanks for the correction Bill. I bow to your knowledge.
You may "when I get the facts wrong I'm willing to eat my words and I
got this wrong, so I apologize ...", but you will also note that no one
found it necessary to try to crucify you, or make disparaging comments
about your error. It was no big deal. We all mix up the model numbers
sometimes. Considering how many models their are, it's not a big surprise.
But you, in all your "wisdom" couldn't hold your typing fingers without
making a completely uncalled for, and statistically inaccurate statement
about me, could you?
My statement about the 4000 was incorrect, however, it is correct about
the 4800 which was what I had meant to type, and as I recall, the X600
series wide carriage, as well, which have 7 heads and cartridges. Epson
uses 8 cartridges in the 4000. They also use 8 in the 4800, 7800, 9800.
The 4000 uses CcMmYKKk, the two uppercase K's are for the photo black
and the matte black, as you state. In the 4800, one of the full blacks
is replaced with a second level of diluted black, to make a three
density black set. To accomplish that, it requires that only one full
black can be installed at any one time. So, the scenario I "painted" is
not true of the 4000, but is of numerous other Epson wide carriage
models. It is also why your waste ink container has a lower demand
placed on it.
Being "correct" is nice, but being a grown up is a WHOLE other thing,
and perhaps one day, you will actually get there.
