Digital BW, The Print

I have had the printer for about 6 months and am using the Epson K3
inks. The problem started about a month ago, but since I print
primarily B&W, and when I do print color, not all of them are
affected. Specifically what I mean is that every time I run a head
cleaning, the test afterwards prints beautifully except for the
yellow. I have run several cleanings and although the condition
improves, it has not disappeared. Any time I make a print that has any
significant amount of yellow in it, I get a very faint banding. It can
 be seen with the naked eye, although not easily, and maybe not even
if you weren't looking for it.
