For some reason the yellow head is failure prone on the DJ 130. I just
did a complete replace of the printer service station, tubes, etc. and
it still failed.  Right now I am on my third new yellow head and 2nd
new yellow cart and the problem has not recurred.  If it returns I
will give up and get rid of the 130NR for good.  I only keep it for
sheet feeding. Otherwise I use a Z2100.
My advice, if you can stand to put any more $$ into it, is to change
the head and the ink cart one more time and make sure they are brand
new.  If it fails again trash it.
