ET-8500 not printing black
My Epson ET-8500 stopped printing both blacks: both pigment and ink one went one after the other, never to be seen on paper again...
I have been stuck with this issue for weeks now, and don't know what else I could do: I have ran cleaning cycles every day (not the deep cleaning, I don't want to do that as I feel it's a waste of ink), I tried soaking the nozzles in IPA/surfactants, I have tried printing the pages that are fully black: nothing helps.
I am wondering if black inks are somehow different in their composition, which causes them to clog up more? The other colours print perfectly fine, and if they clog up,. they clean up easily.
I would be really grateful for any hints or resources that could help me address this issue, as I am at my wits end!
