I think I know what you are talking about. In my case, the streaks were in
the axis of head movement and larger than a dot, but very fine. It looks
like a nozzle leaking; like a fine dribble. I also would get drops of ink on
the paper edge.

Having taken a few Epsons apart and looked at the heads, the cleaning
station, and the printer innards in action, I've seen that the head surface
is perfectly flat with the nozzle orifices drilled into the head surface.
Ink accumulates as drops on the flat head during a cleaning cycle, partly
because the cleaning operation involves a bit of suction at the waste
receiver as well as firing from the nozzles. There is a wiper that squeegees
the head to clear the drops. I can imagine that as the head wears the nozzle
orifices enlarge to a point where surface tension no longer keeps the ink in
the head and ink dribbles. Or maybe cruft develops in/around the nozzle that
causes ink to wick to the head surface. A drop of ink forms on the head
surface, ultimately growing large enough to catch the paper as a blob.

I resolved the problem with a head replacement. For a 3000, heads ran about
$75.00 & $100.00 (black & color) and a couple of hours of labor are required
to replace them. A special service utility is required to align the heads,
something to consider if your tempted to attempt repair yourself.

I'd consider having the 1270 fixed if it works fine for you otherwise. I'll
guess it will cost $150 to $200 for a black head replacement.
