Hi,

I've got an old Hp Deskjet 990Cxi which suddenly decided to print
nothing. When I send a document to the printer, it behaves as before
(paper is taken, cartridges move, etc.), but the resulting page is
still as white as it was before printing.

The problem does not come from the computer, because I tried several
things. Among them,
* Printing test: holding the resume button for more than 4 secs. makes
it print, but the page is still white;
* Technical test: having the power button hold, and then pressing 4
times the resume button. A page seems to be printed (same behaviour),
but, just as before, nothing is printed, despite cartridges'
movements, etc.

Any idea? I need to make it work.

Thanks.

Maybe you need new cartridges?

Sorry, I should have mentioned that they are brand new (and genuine),
and I tested with two lots.

Next time you post a question to more than ONE group,
put the names of ALL the groupson the TO: line
(separated by commas).

That way, everyone who reads the question can see ALL the responses.
This is called CROSS-posting.
The way you have done this is selfish and inefficient.

Okay, but that does not answer to my original question. Please answer
to it if you have any solution. I'll know it for the other messages.

How can you tell if I have answer your question
if you are only looking at THIS group,
while you have posted it to MULTIPLE groups?

Go look at ALL the places you have splattered your question,
STUPID.

comp.periphs.printers is where you should be asking.

Have you removed the cover on the print heads? Have you pushed the
print head against a paper towel and had ink actually come out of the
print heasd???

Yes.

@ Michael: yes, but the other group is so damn infected with spam that
I don't think it worths it.

Damaged flex circuit to the print head carrage?
How did the problem appear? Was it printing fine one page and nothing
the next? Did it print fine then you replaced the cart[s] and it no
longer printed?
We need a bit more history to offer useful suggestions.

That type of printer has it's electronics in the cartridge.. so when
the cartridge is replaced, so is the print head..

His problem must be the driving end of it in the printer or, some how
the settings at the PC for that printer has been messed up in the
color scaling..

I had a printer in that series that used the same color ink cartridge.
"78" and a standard black.. Print head replaced on renewable of ink.

HP cartridges eject the ink by applying a pulse of electricity to a
heating element in the cartridge. There would be one element for each
color in a multi-color cartridge. Since you have tried different new
cartridges, and a self-test you have eliminated the cartridges and the
computer. That leaves the cause as something internal to the printer.
This would be a failure of the printer electronics, a flaw in the
cable connecting the print head to the electronics board, or possibly
contamination of the contact pad on the printer carriage.

Well, I moved the printer and washed my cartridges with alcohol. They
were quite old (but new too: just never used for many), and using heat
