Probably through manufacturing flaw there is a weakness for one color to
reach the nozzles. It will most likely occur again and dog the printer
through its life. You could call Epson and they will send you a refurbished
machine that most likely remedy the problem, or take it back to the store,
if it's still in that return time and exchange for another one that will
also be just fine.
Epson has made some wonderful printers. All one has to do is look at its
history. There are certainly more efficient printers in use of ink, such as
the Canon, in keeping its heads clear and running smoothly, which is
something that every user wants in the first place. At this point though,
because invention hasn't developed it yet, there is still no printer that is
using a minimal amount of ink and giving the best photos; and IMHO, Epson
still produces the best color photos of all.
Back in the 50's and 60's one of the most sought after production
motorcycles was a Triumph. It had great looks, handled well, was quite light
and was exceptionally fast. Harleys stood still in comparison, as they were
so heavy and there was no contest in speed. However, there were two things
that every Triumph owner had to accept if they got one; it constantly leaked
oil, vibrated enough to lose a muffler every now and then, and it would need
a valve job at about 5,000 (not a printing error). One would think that
Triumph could have at least made an oil pan gasket that wouldn't leak.
Still, Triumph couldn't make those motorcycles fast enough to fill the
demand, until Honda and Yamaha started making inroads in the early '70's.
So what's new?
