is there some way to get a color printer going again after some downtime? I already replaced cartridges.?

Question

EPSON cx6400

Answer 1

OUCH
You really are in a precarious situation.....

The problem has nothing to so with the ink in the cartridges on
the TOP of the moving print head assembly, but rather, with the
tubes running FROM the ink at the top, down, into the the PRINT
nozzels... These tubes are LONG, and the ink is deliberately
FAST drying, so that the ink in the tubes dries out from both
ends, if given any opportunity to do so. The ink right at the nozzel
holes is the FIRST to go, normally, since there is no way to protect it -- the top end of the tubes usually has the ink refills sitting there, with " some " ink, which keeps that end from drying out. The WORST case is to remove the top carts, say for example, to go to the store to make certain that you have the right replacements, and then leave the carts off for a long time...
this is deadly... Epson had dozens of identical looking carts, with horribly long, almost identically numbered carts, that are NOT the same, so that this is a REAL problem, and I know lots of people
who have spent a lot of time and money getting carts that are the wrong ones...Make certain, to start, that the numbers are IDENITCAL to the ones needed...
Once the bottom print head nozzels are dried, and/or the tubes ABOVE the print nozzel heads start to dry, there is no easy way
to get at the dried ink...

On the web the other day I saw an ad for a CLEANING SOLUTION for print heads, which claimed to solve many similar problems, and you could try a search for similar products...

On " SOME " printers, the print head can be removed, like on
many older Canons, and with HP and Lexmark, the print heads
" ARE " the ink refills, so this solves the problem...

Epsons bolt the head onto the rail, so that getting cleaning solution ( which I have stopped using ), or just water, ONTO the
print nozzle holes is difficult - but not impossible, and on the
web I have read a number of reports of people who have revived
a dead print head... you have nothing to loose by trying...

Here is a typical answer that I have given in the past...
( try not to be prematurely discouraged... follow the suggestions
since the degree of difficulty is different in every case - you
may have complete, easy success .... )

Also, a note to the text below.... The vaccuum system used to
"clean" the Epson printer heads is connected to the ENTIRE
print head... this means that, for example, if Yellow and
RED print head holes are clogged, the vaccuum does not
change its location or pressure, so that the "clean" process
sucks twice as much ink out of the BLACK and BLUE ( Since
the yellow and red are clogged ) and has little effect on the
desired purpose of actually "cleaning" the clogged print holes. This explains why some cartridges can be almost empty
and others almost full, while the "estimated" ink levels
show all colours are equal. The vaccuum process on the new machines
only works when there is no problem in the first place, and
wastes huge amounts of ink...


I have a couple of new epson printers.
The new cx printers are extremely hard to fill. How did you fill them in the first place?
If you drill or melt a hole in the top, in the EXACT
correct position, and slowly fill them, letting the air
and ink bubbles exhaust, then, they are "full".
I weigh the cartridges when new, and when empty, and
when re-filled, so that I know if indeed, they are
re-filled. You can now buy gram or ounce weight digital scales
everywhere, including kitchen stores, and retail outlets,
and they are 20 bucks or so, and very accurate.
Check the carts to see if on the front, bottom or back
edge there is a tiny green circuitboard attached to
ink cart with two melted dots of case plastic posts.
If so, then you have otherwise, a piece of plastic,
contaning 35 cents worth of ink, with a self-destruct
programmable chip on it. Every time you use ink, the
chip is programmed by 7 gold contact points, and the
printer "guesses" how much ink you have, and subtracts it.
At about 25 per cent to 33 percent full, the chip is
told that you are out of ink. This rather full piece
of plastic, is then DEAD, and cannot be used again.
I have used a new, FULL cart, and simply run the CLEAN HEAD
Epson utility a few times, and been told that the carts are now
50 percent Full ( HALF EMPTY !!! -- and I hadn't printed
anything yet!!! )
The extra caution in telling a cart with ink in, that it
is empty, is done to prevent the cart from ever really
emptying, which would suck air into the carriage fill
post nozzel, and into an inch or two of piping inside
the print carriage / head assembly, and in 20 minutes the
ink inside these tubes would dry, and almost permanently
destroy the tiny print holes ability to re-wet with any
new ink.
If you take out a cart, you must either put in a new one
immediately, or re-fill immediately. I have seen many
Epsons in the garbage - all with badly dried print head /
carriage assemblies - if you have a SCANNER/ PRINTER,
such as my CX printers, the second the print head is
"told" by estimation software, that it is "empty" the
entire machine, including the scanner is DEAD, since,
when you turn it on, you cannot get past the ERROR
ink out message !!!!.
The Espon printers with the "new and improved" print ink
heads and ink carts, are EXTREMELY fragile, and will
self-destruct at the tiniest problem. If the power goes
off, and the head is not parked, it dries out. If you
take out a cart and go to the store with the cart to
make certain you have the correct one, the print head
dries out. You cannot take out the print head to soak
it in water without completely tearing the printer apart,
and removing the delicate microfilm plastic position
strip, and the drive belt, and many fragile parts...
If you do manage to get the print head out, the print head
is extremely delicate, and ordinary tap water will
contaminate the print head holes, and actually
clog the head worse than the dried ink. Using paper
products with sharp cellulose fibers clogs the heads,
if you wipe the heads.. ( one webiste uses strips of
coffee filters and distilled water, with some success ).
The green, self destructing programmable chips on the
empty pieces of plastic cases, ARE RE-PROGRAMMABLE, and
programmers are available at most decent computer retailers,
such as COMP USA, FRYs, Staples, Business Depot, etc.,
since these reputable companies know that the customers
are being ripped off with being forced to purchase 50
cent ink carts, that are not even empty, for 40 times the
cost of manufacture! You MUST make certain that the programmer
you purchase LISTS the printer model, or the cart model,
since there are dozens of programmers, and Epson keeps
changing the programming on new models, so that customers
are forced to buy only over-priced Epson" carts!
I am surprised that you state you FILLED an Epson cart,
which is one of the most difficult carts to fill ( I have
hundreds of printers), and yet you don't know about the programmable
chip on the side of the cart...
I use advice from several Epson user sites, and cut out
a section of useless plastic on the top of the cart,
and cover the melted access hole with black electrical
tape, which restores the cart back to the original
micro-channel air ducting. Leaving a big, ugly gaping
hole in the top, as all webistes I have seen, tell users
to do, in view of how fast the ink dries rock hard, is
stupid, to say the least.
Search dogpile.com or yahoo's search engine to find
EPSON INK REFILL website pages, and there are some excellent
resources, with pictures.
Generally, anyone I know who has been inadvertently
duped into purchasing one of the new Epson programmable
ink cart machines, eventually throws it in the garbage
in frustration. Sales people are either ignorant, or
devious, in not telling customers that they are buying a
product that self-destructs, and wastes ink, and is
extremely fragile. Even the EPSON instructions have pages
of warnings of "do not touch " this, "do not do that"
Caution - you must Immediately replace cart, etc. etc.
and these warnings are SERIOUS. Most people don't even read
the pages of fine print.
I will never purchase an Epson programmable chip printer
(printer scanner) etc. again, and will tell everyone
who asks to avoid them like the plague.
SOOooooooo....
As long as you replaced the carts IMMEDIATELY after re-filling, and parked the heads properly, your machine
is probably not dead ... YET. Every minute you wait with
out printing a page, causes the print heads, EVEN PARKED,
to dry out - the pad that they sit on "helps" to seal out
air, but is connected to a vaccum pump that sucks ink
out every time the unit is turned on, AND, the fiberous
material the heads rest on gets saturated with gooey ink,
that eventually hardens by itself, no matter what you do !
The assembly, the heads, and the design is inherently
self-destructing, without a great deal of difficult
cleaning and maintenance, which is totally beyond most
typical consumers.
If you really want to keep the machine, have TWO sets of
ink carts, - one set always full. Tape the bottom hole
of the full, spare set, after filling (clean it first),
with black electrical tape to seal the nozzle from dirt and air.
Put electrical tape over the air hole you created to fill it.
When the carts show the EMPTY warning, and the machine
halts dead, quickly install the new, re-progrmmed, filled
ink carts, and then print a test page, etc.
Re-fill, and re-program ALL the inks carts you just removed
(not just the one that first reported it was "empty" ),
and tape over the holes, and set aside. Weigh the "empty"
carts before and after filling - you will find, surprisingly,
that even though the ink status monitor shows 3 carts at
25% empty, some will be practically full, while others are
truly almost dead empty... (which is dangerously close to
sucking in air and destroying the print head !!!! )
You "can" keep one of these machines up and running
efficiently and COST EFFECTIVELY, but it is a pain in the
butt, and messy, -- The only "OK" thing about these
printers is that they actually DO deliver a reasonable
quality print when they actually "work" properly.
Going out and purchasing cases of new, EPSON brand
ink carts would bankrupt most users, and would be
ridiculous beyond words in an office environment, where
hundreds of pages are printed a day. I have seen many EPSON
printers with RED and YELLOW ink passages dried rock hard
-- with brand new full ink Red and Yellow carts on top --
because in an office environment, hundreds of black and
white TEXT pages are printed, and Epson uses BLUE and BLACK
to make the black printing, but NOT the Red and Yellow,
which dry out solid - in a brand new machine, which is
in use everyday, and parked properly, with brand new
EPSON carts, which have to be purchased regularly, to
keep the Black and White pages going, EVEN THOUGH the
old Red and Yellow carts are absolutely FULL, - since the
the printer has no idea how much ink is really being used-
just that the carriage is going back and forth, and
it "estimates" that the red and yellow are, eventually
empty, even though the ink tubes and print head are
rock solid with ink, and the New, FULL, Epson Carts, are
never used. -- they can't be used, since the tubes are
blocked solid!
I hope this advice helps to keep your machine going a
bit longer. You need a great deal of luck. You need to spend an
hour ot two on the web researching how to fill the carts
properly, and how the inside technology of the manifold
air/liquid compartments work, and how to HANDLE the
carts carefully, etc.
Some of the NO-Name, non-Epson carts are cheaper, and
MUCH easier to fill, but there are to date, no web instructions
on how to re-fill the clone carts. They also have the
"new and improved" Epson feature of killing your print
every time with a message that you must acknowledge,
stating that you are NOT USING A GENUINE EPSON ink cart,
and print quality may suffer - do you wish to continue?
This deliberate halting of normal print makes using
clones very time consuming, and difficult - which, is of
course, exactly what the Corporate Epson executives
want to do in the first place !! To get around this, you
can take the original green chips off the original
Epson carts, and put them on the new, easy to fill,
clone carts, and the printer will never know the difference.
If you REALLY want to make the units easy, you can rip apart the
printer, and remove the green circuit board from the
printhead, with the gold contacts, remove the thin plastic
electrical cable that plugs into the print head ink cart
sensors, and place the cable on the top of the printer.
By placing the chips on the cart reader on the TOP of the
machine, the stupid "estimator" program will think that
the carts in the print head are connected, and give
warnings on the completely non-working chips on top of the
printer. You can then quickly re-program the accessible,
top mounted chips, and only replace ink carts that are
actually getting low ( you can weigh them), in half the
time and effort. However, since the carts do not hold
very much ink in the FIRST PLACE, you will still be forced
to refill on a frequent basis.
If I ever get the time I have a few other mechanical and programming
ideas to try to see if I could continually re-program
the ink cart chips on top of the unit automatically,
and use micro plastic tubes to permanently fill the carts
on the moving printhead, using huge bottles of ink, mounted
on the back of the machine. The Epson carts have an anti-
overfill, anti-drip pressure operated diaphram fill
mechanism which would work under such a scheme, but would
be too difficult for the average home or office user
to build and install...
Generally, for all the ridiculous expense and time and
problems encountered with this Epson line of printer
( and printer /scanner) I would simply buy something
else, and avoid the problems. Sony got greedy and deliberately put
viruses on new-instore music CDs, and Epson, in my opinion
got greedy and invented this printer from hello...
Both companies are shooting themselves in the foot, and
making people AVOID their products....
Again, good luck. Please do your homework on the web,
and observe all cautions and warnings. This is one case
where every piece of fine print REALLY applies!

___________________________________________________

As you can see from past discussions, you have to act quickly
and carefully to recover from dried ink....

hope you " WIN " the battle... try the suggestions above...

If you have any more details or questions, post them as comments fairly soon... people only look at recent questions
generally, so that you want to act now.

hope that this helps get you going.... Epson, when it works,
has really good printing, so that it is worth a bit of effort
to see if you can revive it...


GOOD LUCK

Answer 2

Epsons have an integrated print head, if the print head is clogged than there is nothing you can do short of trying a number of print head cleanings (your manual will tell you how) If there is no improvement after about a dozen cleanings than unfortunately you are S.O.L, either have the printer serviced or replace the unit.
