1) What type of paper and which ink are you using?

From the look of the scan, it looks like you are using an incompatible
paper for the inks you are using.

2) When you look at a nozzle check, are all the steps evenly spaced in
terms of elevation to those to either side of it? Are they all of equal
density? Do any seem to appear on the same line or even in reversed
position?

If so, your printer head is suffering from deflected nozzles. It's
cause is usually dried ink under the head causing the ink to apply too
high or low, the same way water is diverted when you place your thumb
over a garden hose.

If this is the case, contact me via email and I can provide you with
instructions to clean the underside of the heads.

The nozzles are perfect.
I take the same results using dye and pigment ink on epson and HP
paper.These days i'll try more papers but as you can see on the first 2 cm
of the scan the printer starts printing perfectly and when the paper starts
going down the banding starts!!!
thanks

You need to contact me via private email, not via public posting. I
will then gladly send you the instructions.

Can you send me a scan of the nozzle test printout via private email, in
300 ppi/dpi resolution (just of the nozzle check). Jpeg it as a with
very low compression please, so it will not get artifacts. Also send me
in the same resolution, a small 2" x 2" section of the area of the print
which the quality transitions from good to bad, so I can see it more
accurately.

You mention using HP paper. In many cases, this is an inappropriate
paper for Epson inks. I suggest you try some Epson paper and use the
proper Epson profile in the driver for that paper, and see if you still
have the same problem. Make sure the head height position is correct
for the paper type.

I am not advocating you have to stick to Epson paper, but to test for
what's going on, it is a good idea. The banding I am seeing on the
print scan you provided (within the limitations of the resolution of the
scan) looks to me like reticulation, which is caused by an
incompatibility between the inks and the paper.

However, the fact that you consider the beginning of the print "perfect"
and that it degrades part way through could be intermittent clogging, or
ink starvation. In starvation often results with perfect nozzle tests,
good starting of prints, and then degrading as the print continues.
It's most common causes is blocked air vents in the cartridge, but there
are other causes.

Using HP paper in your Epson is not going to give the best results. Same
goes for all companies. What settings are you using?

And I sent you not only the manual, but a personal set of extra
instructions, which I wrote specifically for your situation.

I don't do this for a living... (If I did I'd have starved to death a
long time ago, since I don't charge anything) I do it as a way of
helping others and I try to do so in a timely manner, but... I have a
family, and work, and I also do a bunch of other volunteer activities I
attend to.

I really do attempt to answer within 24 hours, but sometimes other
priorities force me to answer a bit later.

Also, my internet connection has been known to go out for up to 72 hours
on occasion, and there isn't anything I can do about that. Telus High
Speed Broadband ADSL, for those who wish to know.

I have even been known to get ill, hurt my back and been unable to get
out of bed for 3 weeks, and horrors! gone on vacation for a week.

I've also have more email bounce than I care to tell due to people
requesting the manual or my assistance and then forgetting to lift my
address from their spam filters.

I really do try to get back to people ASAP, but quite honestly, I give a
lot more rapid service than most printer companies do, so please, give
me a break...

Thank you.

Hopefully, a few people will read my reply and understand what's up. I
reply to every request manually (no automated reply system) so I can
read each request and supply additional help, where required.

There is something about the impersonal and rapid nature of email that
makes people quite impatient.

I know people get upset when their computer or peripherals don't work,
especially if they are in the midst of some project or another, but, the
vast majority of people who reply in newsgroups do so on their own time
without any compensation. Most have other paid work, and other
responsibilities, and due to their nature, often have many other
commitments which require their time and energy.

People might notice that I usually answer my messages between about 11
PM and 5 AM my time. I'm supposed to be asleep! My wife likes a warm
body next to her, also, but that's the time I have to to help people on
line.

I'm not complaining. It's my decision to do this, but I do ask for a
bit of patience and understanding if I cannot get to every email
rapidly. I'm just one guy.
