This sounds to me like cross-channel contamination. If it occurs after filling then it could that the carts are draining or dribbling into the capping station after filling, which spreads from one channel to the other. If it clears readily after filling, e.g. by printing purge patterns as we discussed on IJM in relation to your 1430, then I suspect the carts. Head cleans can also help, but you know my views on those. Cross-channel contamination can also be caused by a dirty or faulty capping station, so I'm told by IJM.
In relation to your other question, I no longer look at the Epson printers group often because I found the signal to noise ratio a bit low. I wouldn't assume that the B&W and QTR crowd read it. We're more interested in the science and art of printing monochrome than in printer maintenance per se.
