So I recently bought an Epson P600 for my first photo printer and I've been testing out different paper samples to find something that I like. One thing that I'm noticing is just how quickly it's using up the Photo Black Ink. I've done maybe 20 8.5x11 prints and it's giving me the low ink warning, while all other ink levels are still in the 70-80% range.
It could just be the sample image that I've picked to test with uses a lot of black ink, but I'm printing on matte paper just as frequently as photo paper and the Matte Black Ink isn't any lower than the other ones. Also, though this could be my imagination, I seem to lose ink whenever it's switching between Matte Black and Photo Black, but again, it's just the Photo Black that seems to be dropping.
What am I missing here? Is there something I should be doing to better manage how much of the Photo Black ink it's using?
