[Dead] Colorqube 9301 printhead issue

[LamsterPaul]

I had a big problem with my 2 colorqube 9301 machines,
after a faultcode I open the the machine and i see, that the upper printhead looks like, that
it have a ink leak inside and the hot ink was going down and was leaking on the head at the buttom,
and destroy the head and i had a fault on this head
after an new installed head the machine runs fine,
but i see on my second colorqube (from where i get the parts for temporrary trying) exactly the same leaking on 1 printhead

is this a know issue ? And what is the fault ? Printhead or from the ink pipes ?
pipes look good

please tell us you didn't tip the machine while the ink was in liquid form?!
what is the page count on it?
who replaced the PH?
did they also replace the wiper blade?
you mentioned a fault code? what was it?
the ink loader could be bad causing the spill.


really if you are going to ask for help you NEED to supply better information.

Re: Colorqube 9301 printhead issue

i hate to assume you are a tech from your explanation.

are you sure you got the process control gears timed properly?

when you replaced printhead you SHOULD replace the wiper blade assm.

it can be tricky to get the PH installed with out damaging the ink ports... you didn't bang or bump the printhead during install?

Re: Colorqube 9301 printhead issue

Thanks
the printhead installing was not so difficult,
I also had replace the umbilical kit on an other maschine without problems,
the ink was comming out from the printhead on the PCB board, not from the connector
so its looks like the printhead itself was the problem,

now the machine works again, with the 2 new printheads, but i will know the reason, why this fault was,
to prefer to kill another printhead

ok.. have tried... BUT UNTIL you can give me the NUMERIC fault code I will refuse to try and help you.

" but i will know the reason, why this fault was, to prefer to kill another printhead"

do you WANT or WILL know the reason ( need fault code XXX.XXX(.)xxxx )

I would prefer NOT to kill another printhead either!

NOW..MOST TIMES, ( -=key words=-) when a solid ink machine spills the ink onto the printhead BOARDS ( like in your pics - not what you call printhead 1-2-3-) these things SHOULD have happened:

1) machine was moved/tipped within 30-60 mins of quick shutdown (not the MOVING shutdown)
2) wiper blade assmy NOT sync'd
3) process gear train NOT sync'd
4) ink loader malfunction (overheat)
5) loader sensors not operating properly
6) NON-Xerox solid inks

** NOTE : I have been working on these solid inks since shortly after inception. **

Re: Colorqube 9301 printhead issue

I was today om the machine again, the fault was 99-061 cable video printhead 3,
the error was from the ink, that was melted the printhead cable on the head,
so i replace it,
also error 91-698 was showed in the history,
I also had performed an DC971 after replace it,
I will check the head tomorrow again, to see if the used upper PH will leak again,
if this will again, Im looking to replace the umbilical pipes too,

on my second CQ9301 I had the error 93-539 Umbilical thermal error,
so I order the Umbilical Kit for the lower PRintheads. The upper was replaced last year

where the INK will leak often ? At the Seal of the PH to the umbilcal kit ?

I often had problems with the drivebelt of the Drum (had always 1 in stock)
the CQ not so bad, but need often Maintaince

Re: Colorqube 9301 printhead issue

For what it is worth, I have replaced dozens or printheads on Colorqube that have leaked. Many have looked just like the pictures posted. There was a xerox procedure to seals up printheads, but my company declined to do that procedure, so I don't know if it helped.

If installed properly, and the post install procedures performed the leaks didn't return. I always liked to clean off the buildup wax on the umbilical before installing the replacement printhead. That said, the pictures show internal leaking, not from the printhead/umbilical joint.

If you are interested, I have a few printheads for sale, pretty cheap, just PM me

You can't swap used colorqube heads around... they at best have a 50% chance of re-sealing.

I rip down a 100+ colorqubes a year and find this kind of blowout in more then half of them. The heads just dont seal up consistently. Even from the factory. Tip or no tip. 20,000 copies or 6.5m.

Mean you this seal kit ?
Xerox: 607K03170 ?

will it work with this seal kit, or it is wasting time ?

and this really works and solve the leaking problem ?

This fix is for the internal head blowout issue, which I only see so often. I also heard it will prolong head life but I think it's a waste of time.

Usually when I see a complete mess of ink inside a qube' it's due to leakage from the rear seal at the umbilical. Leaks from the umbilical down the back of the head and goes everywhere.

Once they leak you just have to chuck the head and try another one.

If you listen during the initial purge after a head swap you can hear the leak most times.
