I have been having problems with a C84. Blue was printing incorrectly.
I ran the nozzle check routine and the printout was fine except for
the blue. the jet does not appear to be blocked as the line is all
there but it appears to be chopped into tiny sections which are sort
of scattered in a random way. They are nearly lined up. Any ideas
anyone?

I know this sounds as though I'm being nitpicky, but it's an important
distinction. The C84 does *not* have a blue. Epson only make one printer
that takes a blue cartridge and it's sitting next to me. The C84 is a
four-colour unit, taking magenta, yellow and cyan. Cyan is *NOT* blue. Blue
is blue. The R800 is the only printer that I know of to take a blue tank.

If you think you have an alignment issue, why have you not run the printer's
alignment applet?

Ok the problem is with the cyan jet.
I have run the printer's alignment routine. It made no difference at
all.
There is nothing provided in the maintenance ara for this printer that
will sort out this problem which is why I am asking for help here.

Not wanting to sound picky but isn't cyan a shade of BLUE, a kind of
greenish blue?
 
You are being nitpicky, but then again you always are, so I won't be
nitpicky about your being nitpicky ;-)

Cyan is a blue-green or turquoise, so it may be considered a shade of
blue or a green, I suppose.

Now, as to actually trying to HELP this person...

Chances are the nozzles are partially blocked. The nozzles work a bit
like a very small hose that fluid passes through. If you take a garden
hose and you place your thumb over it, the water flow gets fractionated
and is no longer accurate. The same happens with an inkjet nozzle that
is partially blocked. The ink sprays all over the place. I refer to
that as a deflected nozzle.

If you look at your nozzle test, you will probably find some steps are
either too low or high or even off left to right (late) or are broken up.

The fix is probably an underhead cleaning, a very commonly required fix
for Epson printers.

To learn how to do this and what materials to use, please email me in
private mail and I will send you a manual which explains the process.

No cost, no spam.
 
I would not worry too much about a flame from "Miss Tick" as "She" seems
to get "her" underwear in a knot about quite a few things.

Hey Arthur!

I've read enough of your posts to know that you do indeed know your subject
very well.

BUT why not provide the manual to all of us readers in the group?

The group is whence the query originated.

One of my pet peeves is the use of private e-mail to correspond about
Newsgroup Problems.

I know you are intelligent enough to explain the answer to the entire
Newsgroup concisely and correctly.

Please!
 
Hey Arthur!

Forgot to say that I have an Epson C84 working just fine.

Had to read the manual carefully, line by line, and page by page.
 
There are literally dozen of reasons I do not post the cleaning manual
on any newgroups or lists.

Some have to do with legal liability, some are because the manual is
updated quite regularly and when people email me they get the current
version. The manual is copyrighted and owned by me. People seem to
assume anything that gets onto a newsgroup is public domain, and the
manual is not.

The manual contains certain caveats to both protect people from injury
or damaging their printers, and to protect me from liability. I do not
wish the manual to end up edited and missing those aspects, or otherwise
altered with my name on it or not.

The manual is quite long (about 60k of text), and some people would
object to my posting it every time I made a change in it. There would
be dozens and dozens of versions all over the internet and some would
have outdated or possibly contain erroneous information in them.

I know every address I send the manual to, so if I need to send out a
correction on one version of the manual, I know who legitimately has a copy.

I sometimes tailor my responses to individuals depending upon what I
perceive as their level of understanding of mechanical or electronic
aspects of the printer, which printer they have, or their language
skills, since these are international forums. Some of the discussions
are so technical, there might be 10 people in the world who would care.

Some models change numbers depending upon where in the world they are
sold, and this can be misconstrued or misunderstood by people with
similar sounding model numbers that are different.

I often need to see attachment files or images or scans of the problem
and that cannot be handled on a newsgroup.

Some of the minutia of working out a problem is very tedious and would
not make for interesting reading. By dealing with each person
individually, I am made aware of new issues, areas that need changes or
expansion, new problems that arise, and can communicate more freely
about subjects that may not be easily and freely discussed in a public
forum.

I often need to expand upon explanations beyond the manual. Sometimes
people mistakenly generalize something I might be instructing for a
specific model and assume they can do the same for their model and
therefore damage their printer.

I am occasionally aware of specific problems that have come up in
certain production runs, or am made aware of this due to repeated
requests, or I know of a bad run of ink or a certain brand of consumable
that is causing a specific issue and I am not always at liberty to
publicly discuss these things.

So, ultimately, I have found that a greater good is performed by working
as I do, than to simply toss the information to the wind. And that is
why I continue to operate as I do. Believe me, it is a lot more work
for me, but it also assures of more valuable service to others.
