QTR-Quadtone RIP

When you look at the detail it sure looks like the LK is not aligned with
the K. Each letter has a LK shadow displaced slightly above the K forming
the detail (letter or line). The printout from the maintenance panel (and
any other non-QTR) source might be sharp simply because it may only use the
K ink. The 2200 QTR curve has grey overlap and therefore uses LK and K to
make 100% black used for the lettering and lines.

Another possibility (I think less likely in this case) is that blurring can
be caused by putting too much ink on the paper (i.e. the Curve is not well
formed). From my experience on a 2200 this would result in spatter and more
general blurring than is the case here.

It's a bit hard to tell onscreen but it does appear that there is
spatter occurring. I would try cleaning the underside of the LK head
using the techniques listed in the wide format groups archives and
putting windex w/ ammonia d on it's cap station and leaving it set
awhile before a couple of cleaning cycles, to see if that helps. It
takes very little jet deflection to create problems like what you seem
to have. It could be nothing more than ink buildup under the head.

You may also want to do the more extensive head alignment. This was a common
start up problem for 7000, 9000 users of the early piezotone users. It uses
several yards of paper but will give you a better sense of your deflected
heads than a simple nozzle check. Check your manual for the procedure.

Thanks for the feedback, folks.

I've done the full set of head alignments, using the printer panel (no
change), the software driver (no change) and the printer utility (no
change).

And I've had an even blurrier print using the Epson driver, so I
don't think it's the QTR curve.

I've also adjusted the platen gap and again no change.

My Epson service rep recently gave me some head cleaning liquid, which
I've used just now to soak the capping station sponge and park the head
overnight.

Still, I suspect the head will need some direct cleaning, since my
printer was a demo unit that was parked on the showroom floor for 3
years with only intermittent use, so I imagine there's some dried
ink in there. But before I clean the head I will consult with the
service rep because I don't want to risk damaging it.

I found some instructions on how to clean the head here 
<http://www.piezography.com/support/printhead_cleaning_tips.htm> - (Tip
#6)

I gather these are as good as any?

Thanks again,

Mark

Hi Mark,

It sounds like an alignment issue.  Like maybe one head is up or down
a whole inkjet spacing.   This might make it look aligned but in fact 
the
jets are off by one.

I'm not familiar with the actual alignment procedure but maybe that
could be revisited.   A 720dpi file with just a few horizontal lines
one pixel in height should show what's happening.  Try this with the
Epson driver with various colors on the same line, you might see if
some are off of alignment.  I've also done some test files in the past
with QTR to show this same thing.  Let me know if I can help.

The towel under the head cleaning described is fine. To clean Inside
the head, you can actualy print rather than do a transport flush as
described. Using a cleaning cart (from Mis or other supplier), just go
get a banner paper roll and using the banner paper and the cart print
about 9ft(or until no color shows) through the proper spot eg:LK. That
will empty the ink lines and head and put the cleaning solution into
the head. Let it set awhile to soak and then put your LK cart back in
and repeat the printing to get ink back into the lines and head. That
should flush out stuff inside. I, personaly, just loaded a cart with
1:10 clear household ammonia(Not soapy or perfumed stuff) and
distilled water and used that on my 7000 to do this. It worked just fine.

Duane

Update: Turns out the print head needed to be replaced. Now it's 
working fine.

Thanks to all for the tips ...
