According to this article - tests done on the P600 by Red River Paper
the ink used during black conversion is...
* Matte to Photo Black approx. 3 ml
* Photo to Matte Black approx. 1 ml

"EPSON P600 User Manual - page 137
Switching the Black Ink Type
Switching the black ink type takes several minutes and consumes some ink in the
process. Check the black ink type media list to select the correct type for the
media you loaded.
1. Press the home button.
2. Press the black ink change button.
3. Select Proceed and select one of these types of black ink to switch to:
• Photo Black to Matte Black—switching takes about 1.5 minutes
• Matte Black to Photo Black—switching takes about 3.5 minutes"
I would imagine that the two Black inks use the same feed lines in the head
from this, and likely because of the added cost of doing independent feed lines
(and whatever other complications that it might entail). But that's as far as I
am willing to conjecture. I don't design this stuff, I use it. Far be it from
me to tell the engineers how to do their job.
I turned off autoswitching because I only rarely print on papers that don't
take Matte Black ink and found that if I chose the wrong paper type at first
then later changed to the correct paper type, the printer needlessly cycled
back and forth wasting a lot of time and a bit of ink.

Godfrey,
That information that the printer has an ink-changing cycle is interesting.
But what is actually done during that cycle?
I assumed that having both blacks simultaneously spares you from any
ink waste, and what I am reading from your suggests (if I understood it
correctly), that could be a wrong assumption.
But I am still curious, - what do they actually do? Purge the nozzles from one
black and initialize them with the other one? That would mean
that despite having both black cartridges installed at the same time, they are
multiplexing the head nozzles.
But why? Why wouldn't they have separate sets of nozzles, just considering
each black as a separate color (like they do for Light Black and Light-Light
Black [LK and LLK])?

BTW: the P600 ink tanks are much larger than R2400 and R2880. They're up in the
20-25 ml range. And the Photo Black and Matte Black inks are installed
simultaneously … the printer will even change ink mode automatically based upon
the paper you select, if you enable that option. (I don't, because it means
more possibilities of an ink change cycle which takes time and costs ink.) I've
found the P600's ink tanks and general economy in printing reduce the per print
cost quite significantly over the R2400.
