It's been a long time since I used a 7600, but just looking at the issue of ink maintenance, I think if you agitated the carts, did a nozzle check, and printed an 8x10 purge pattern once every 2 weeks you'd be fine. I keep both my 9800 and 7800 going doing basically one serious print a week, both included.
Frankly, I've never had an Eboni-6/Carbon-6 wide format printer form sediment that was an issue. What happens with Eboni-6 is that the particles float down a bit, but they are compressing electrostatic springs. The pigments are not clumping. With agitation they spring back to an even distribution.

I have owned two 7600 and currently have a 9600. I set one of the 7600 for color printing and had Eboni inks in the other 7600. The problem I had with these printers was not using them enough. I made a habit of running a test print every two to three weeks and that did not help. I still would get a clog on one or both of them. But I also am handy and was able to clear the clogs up without issue. The prints from both of them were very nice. I got those 7600 for about $100 each so the money I spent in ink was my biggest cost.
Qimage now has a automated way to send test prints to the printers. You should look into using that.
