Just as a further aside, I just remembered that the Epson reservoir designs are more aimed at not allowing ink to leak out of the vent channel. There is absolutely no pressure offset like the standard CIS Marriott bottle design so the Ecotank printers are sensitive to there being too much ink in the reservoirs.

I don't think so, I have/had verious L.. and ET.. printers in use and took some apart, the air is fed to the bottom of the ink container, that's below the nozzle plate level, there is a pressure differential of a few cm, but this only works as long as the refill openings are closed during operation, with a rubber plug or with the cover on the ink compartment.
