Digital BW, The Print

Hi. Can anyone tell me the current part# for the lc/lm/y print head
for the 7000/7500/9000/9500 machines. I need to order one and my
manual doesn't give the #s directly.
Thanks.

Part number is F055070 for both heads. This is the latest updated
number that I've been able to find. Last time I checked, Vance Baldwin
had them in stock, as did National Parts. Not sure about Agson,
Compass Micro, or any of the other places.
Do you have the full service manual? It should have had a parts list
in the back (section 7?), but would probably have the obsolete part
number listed for the heads. Both Vance Baldwin and National Parts
list the old part number but suggest the new part number for the
replacement.

Greg,

 

My 7500 is in for service also and needs that head.  The service person
commented that it is the same head as the 3000.  Does that make any sense?

Thanks much.
 No, my manual doesn't have a full listing. Instead it just has item
#s and names for the component placement sheets.
 There were 2 different #s listed on the National site and neither of
them seemed to be current.
 I would like to have the full listing for the 7000/7500 if it is
available. I had expected it to be with the manual I purchased but it
was not.

Hi Paul. I'm not Greg but I think I remember Ernst making a comment
some time ago that the 3000 does use the same head these days.
 It might make sense in the context that, possibly, the dot
size/quantity has as much to do with firmware or chip timing as with
the nozzle hole size.
 What was wrong with your 7500? My 7000 is putting ink in the wrong
places, lots of it. I posted on the wide format site but had zero
input from it. The archives here and there have lots of info from over
the years but, unfortunately,none of it was of direct help except in
ruling out things that proved to be ok. Reminds me of years ago in the
studio and trying to keep the color lab running. Days I don't miss a bit.

Regards
Duane

Basically it is the same head as used for CMY in the 3000 but 
there have been several generations and quality control (hand 
picked) was also used. In order of quality: 3000, 5000, 7000 + 
9000 dark side, 7000 + 9000 light side, 7500 + 9500,  so a 
3000 one shouldn't be used for a 7500 but the other way around 
may not be a problem. Roland, Mutoh, Mimaki also used the same 
head in their first generation wide formats.

On the box of the 9000 lc/lm/y one (ordered 2002 in Europe) 
are the following numbers
1057732 --- F055050 --- 2205771 if that is of any help. The 
dark side head had the F055040 number but the service people 
used the light side ones also for the dark side. But that's 
three years ago and the 7500 + 9500 models are a bit younger 
than the 7000 + 9000.

Duane,

>What was wrong with your 7500?

The light ink head was not cleaning well, probably due to too a combination
of factors.  The parking station may not have been sealing adequately, and
the tube from there to the pump may have been clogged.  As a result, for
some time one jet would not clear at all.  Finally the entire head would not
stay clean and the printer was ruining every print by spitting blobs of ink
on it.  Luckily I found a service person I've used before with good results
who would allow me to drop the printer off at his shop (as opposed to the
Epson referrals who make house calls and charge for their travel time from
L.A. -- a fortune I'm not willing to pay).

> My 7000 is putting ink in the wrong places, lots of it. 

I'm not sure if this is the same as your problem, but as noted above, one of
the symptoms I had was "spitting" lots of ink blobs on and by the side of
the print image.  In the past cleaning the wiper blade, etc. cured the
problem, but this time I could not get the job done.  So, it was time to
turn it over to someone with the right skills (I hope).

I'm suspicious that one of my long term problems with large format printers
is that I just don't use them regularly.   I didn't have that problem with
the old 3000, probably because I kept plain paper in the tray and sometimes
just used it for smaller and non-photo work.  The 7500 and the like don't
lend themselves to that kind of use.  I suspect farming out the largest
images and having a 4800 may be the best way for me to go.  (Just by
coincidence, that is the direction my ink efforts are headed.)

Ernst, those are indeed the old numbers. When Epson made the 9000 to 
9500 conversion option, they suggested that each tech doing these carry 
2 spare light ink heads in case of problems. Now Epson only supplies 
the single part number (F055070) and I know it is used for the 
5000/7000/7500/9000/9500 printers, as well as some Mutoh and maybe some 
Mimaki. It is supposed to be of higher quality than the F055050 head.

I've got to replace the flex lines in my 9500, as well as swab out the 
stainless lines, and replace a couple of heads that I cooked. When the 
heads get hot, I lose a couple of nozzles, that comes from running them 
at 100% too often with a bad supply of ink. The peizo gets hot, and 
things in the head change. Then whenever they get too hot, they stop 
pumping like they should. Then the printer will get converted to a 
grayscale system in conjuction with the new version 4 Evolution RIP.

Would this overheating problem argue against my strategy of purging the
lines by printing purge patterns as opposed to doing lots of cleaning
cycles?

One frustrating problem I have with infrequent use of the 7500 is that the
toned, blended B&W inks separate in the lines and/or dampers.  So, to get
the tones back to where they should be I have to purge the toner lines.
I've been printing just the toner inks on cheap butcher paper to do this.
The strategy avoids wasting the un-affected inks, but I wonder if I'm
wearing out the heads and running up my costs more than if I'd just use lots
of cleaning cycles or doing an "initial fill."  Those actions, of course,
probably wear out the pump.

I've also wondered if it would work to put a "Y adapter" (like the one shown
at http://www.inksupply.com/vacfill.cfm) just in front of the damper, and
then just pull the problem ink out of the line with a syringe if the printer
has been sitting for a while.

I'll probably try some sort of daily printing with the "autoprint" program
MIS recommends for CFS units first.  (See
http://www.inksupply.com/cobra.cfm)

Thanks Paul.
Actually,it sounds very much like my problem but I've allready gone
down the maintenance kit plus dampers path and replaced all of the
items you mentioned except the head. None of it helped. I'm hoping
that a new head will take care of it and it isn't in the electronics.
The main difference from yours is that I didn't have clogs or missing
jets first.

Hope all works out well for you(and me).

In my case it will be mothballed for about 6 months every year so I
will have to figure out a way to make it survive the abuse.

Meanwhile the old 3000 I have is still ticking along nicely. I just
brought it back up with the UTFS inkset after moving it North as well.

Duane

Depends how you are running the purge. If you run it through QTR or 
another RIP that lets you go at a true 100%, then it might not be a 
good idea (this is how I killed mine). If you run it through the 
Epson driver, there should be no problems as you are really just 
printing at the "regular" output level. The regular level for my RIP 
is around 60% of max. with some fine tuning on each channel to drop 
it more, so really between 50% and 60% per channel.

Yes that is bad, and a hassle to deal with. Shouldn't you back flush 
those to let everything get mixed again? They must separate in the 
carts too. With a CIS (bottle system) back flushing would be the 
thing to do, but might not be good with a cart system.

Init fill uses 25ml each on my 9500, do you really want to spend that 
much ink? The pump is cheap to replace, and if I ever find the 
correct tubing, cheap and easy to rebuild. The part that wears out is 
the tubing. The capping station also tends to have problems with the 
rubber gasket that seals against the heads (porous pad), but again 
those are cheap and easy to replace (I don't even think they need 
tools to be replaced). I have rebuild the pump with Tygon (something 
or other) tubing, that worked pretty well for a while but the tubing 
finally expanded and wouldn't stay on the porous pads, you really 
need the correct silicon rubber tubing (metric size???).

I haven't had the covers on the head of my printer in years. I'll 
often pull the ink line off the damper and pressurize the ink line 
(through the vent on my CIS bottles) to push the ink out into a waste 
bottle. Or run it the opposite way to flush the ink back into the 
bottles. Depends what I need to do.

Greg.
Why not use most of the tubing that normaly went into the waste box as
a spare length to rebuild the pump and use Tygon(or whatever is used
with IV bags-or better yet oxygen nose kit tubing), connected near the
pump, to go to the waste recepticle?
That ought to at least double or triple the pumps useful life.

Duane

Paul,

I usually do one or more KK2 cleanings when the printer has 
been idle. After that a CcMmYk pattern to get the heads in 
normal condition again. I think printing waste paper doesn't 
create enough flow in the lines to get rid of accumulated 
pigment. It's all more intuition than science though.

One way to avoid any wear on pump or heads is having a waste 
bypass to bottles outside the printer and using a vacuum pump 
on them to pull inks through. Have that on the 9000's and a 
similar arrangement on the 10000. But in practice after idle 
time I use the KK2 cleaning on both models.

Ernst
