The CX6600 uses Durabrite ink, which has earned the reputation for causing
more unclearable headclogs than any other Epson printer that I'm aware.
To give you some background to this premise, I am the tech coordinator at
a public school in Philadelphia, taking care of some 85 Epson inkjets for
the past ten years. About five years ago I ordered 16 Epson C84 printers
(that use Darabrite ink). I put 6 of them into service immediately. Within
two years all 6 developed head clogs that I was unable to clear despite
running cleaning cycles with Windex, alcohol, commercial head cleaning
cartridges, careful injections of those elements, and bottom head cleanings.
Additionally, I discovered that the waste tubes on two of them had developed
hardened clogs of ink themselves.
Conferring, with Art Entlich, who often writes on this NG, and has
nurtured an understanding of Epsons, their ink compositions for both dye
base and pigment base ink, I gained the understanding that Durabrite ink's
formula was pigment base and had a formula recipe that used resins to make
it water proof, light fast, and unfortunately dry too quickly for the
printer's own good.
With this painful understanding I looked for an ink source that might
allow a dye-base ink to be used in the remaining ten C84 printers we still
had in unopened boxes. I came across a company that said they had success
with their ink in C84 printers and also a spongeless cartridge that was
clear plastic, could be refilled multiple times, and a chip resetter that
would renew the chips usage on the cartridges. A year and 9 months later all
ten printers are running, with no head clogs, and we're saving a fortune on
the cost of ink that Epson would have liked us to have spent. The dye base
ink does not have the property of water proofness, or longevity beyond maybe
two or three years for fading, but it does dry relatively fast, and is
perfect for our school environment.
So what I think is happening with your printer is that it's slowly
clogging to death with old ink inside the head. What can you do about it?
Start with cleaning cartridges filled with possibly an alcohol/ ammonia
formula (90/10%). I would run a whole cartridge's worth through the machine
in attempt to rid the head of the built up dried ink that is beginning to
take its toll on the printer. Secondly, I would stop using the Durabrite ink
altogether and start using cartridges that use dye-base ink. That means you
might have to start filling ink yourself if you can't find ready-made ones.
Until recently one could easily find those cartridges, but since Epson
has been suing every third partry cartridge supplier in site those sources
are drying up. I would recommend that you try
www.alotofthings.com to look
at their spongeless cartridges and the dye base bulk ink that you can be
fill them with along with a chip resetter. By the way, refilling these
spongelss cartridges is easy, and nothing like the classic way that
traditional sponge cartridges must be refilled.
