Epson problem

Hi all.

My 890 has started spitting out black ink at random. It seems to be spraying black ink on the rollers, which in turn smudge the prints. I'm afraid it's soething with the print heads, but I am hoping otherwise.

Anyone with more inkjet experience than I care to take a stab at it?

I think I will try the solution posted here:

The problem seems to be dust collected on the print head getting saturated with ink and smearing it across the image and rollers.
