My skies used to be creamy smooth, but now they're, to use a film word, somewhat "grainy". Today I refilled all the carts, some were almost empty, I wonder if that caused the problem because I noticed the graininess before I did the refill. Also, I mixed my ink about a year ago... could the ink have aged or gone bad? This printer is a real ink miser so I've had the same batch of ink all this time. I mixed about 120 ml of each dilution and stored them in plastic bottles.
One more thing... the black cart, 100% Eboni, leaked a little out the port that fits over the nipple, but it stopped once it was in place.
I did a search here but couldn't find anything about graininess with this printer/inkset combination.
Thanks all,
Paul
