Myron,
With the Eboni v.1.1, I've been agitating every 2 weeks. I think that is the same that Jon recommends for Peizo inks. In centrifuge tests the Eboni v. 1.1 performed almost exactly like the Epson K3 MK. (And it settles also.)
I remove carts to agitate them. I'm told some rock the entire 3880. I'm skeptical that is a good idea.
The Inkjetmall 3880 carts have baffles in them, so I'm not sure what is the most effective agitation motion. I also suspect those baffles may lower rate of settlement. A side to side motion would avoid the baffles from stopping the agitation action. Also, a rotation would cause the pigs at the bottom to get swirled up toward the top. So, some combination of those actions seems like a good idea.
Note that Eboni does not just fall out of suspension. It's been described as like a spring being compressed. The dispersion repulsion is not failing. It's just that the electronic "springs" get compressed by the weight of the particles, so that the particles are closer near the bottom and farther apart near the top. The bottom line, however, is that for consistency agitation is the solution.
When I have more experience with the 3880 I'll at least put in the PDF what I do (if it seems effective), but right now I don't have a precise approach.

Paul,
It would be helpful if you included in the PDF a short discussion of how to keep the dilute Eboni in suspension. How often is it necessary to “agitate” the cartridges, and how do you do it? I know you’ve discussed this elsewhere, but it could be convenient to have it here as well.
