I didn't want to mention that but black in the yellow sounds like my old 1500w where I faced the Epson head problem of mixed colors inside the head, caused by a crack in the separator between the ink channels.

I wonder what is the sequence...
If the printer is not used for a while, then the damper has more air and...
