HP yellow inks SEEM to be excessively corrosive.

I have had a DesignJet 450C for quite a few years now, and
the yellow carts have alwys been the most problematic.

I posted a question to the printer guru at fixyourownprinter.com
and he and a couple others confirmed the problems with yellow
ink...here, it manifests itself most commonly as a cart that refused
to print AT ALL. Carts usually plug up some, causing streaking,
but these were completely dead.

Checking the carts via the PC pads that make contact with it
showed that somewhere the copper traces had opened up, likely
due to the yellow ink.

So, I've just learned to live with it.

As far as maunal cleaning goes, if the damn thing's not working,
I figger you've got nothing to lose.

I can USUALLY revive a dead cart (unless it's an electrical problem
as above) by wiping the printhead FIRMLY several times with a piece
of toilet paper (yeah, I know, that's supposed to be a BAD THING, but
it works).

If that doesn't work, take the cart OUTSIDE, somewhere that flying ink
will not get on anything critical, and pretend to "throw" it with the
printhead
facing away from you several times while NOT actually letting go. The G
forces will often get things flowing again. A large arc with the bottom
of
the arc
toward the ground works well, and the ink doesn't get on anything vaulable
this way.

Then follow up with the TP as above.

I've revived MANY $35 HP 5164X carts this way.

In the case of HP 1220
the cartrige has the printing head on it.

in otherwords each time you change the ink, you change the printing
head.

This solves a lot of problems that occure in other printers with
clogging
up ink heads.

Using HP cartridge. But for future, is that the way to go.
Never filled, is doing that a problem?
What about non-HP?

Thanks

There's two parts to the print heads - one is on each new
cartridge and the rest is buried in the traversing print
mechanism. The former can maybe be fixed by cleaning or
replacing but the latter - if messed up in any way - is a
repair bill larger than the replacement value of the printer.

Some people save a lot of money refilling one way or another
and I cannot dispute that. But, if the printer is OK except
for a yellow or other ink issue, why temp Murphy to visit you?

Just my opinion, YMMV.

sure did


My HP Deskjet 1220c no longer prints yellow.

I have a hard time believing I ran out of yellow - I use
the other two color much more. I told the printer to
clean but did not prime.

Also, although I've had the printer for a while I've used
it seldom.

Do cartridge jets get blocked or something that can be
fixed?

Mine has been running flawlessly since Day One. But, yes,
one color can and does run out first.

Are you buying genuine HP cartidges, no-brand, refilling
your own, or what? When I see anything out of the
ordinary, I try printing a couple of copies of a 16-color
image to see which color(s) might be going south. I try
cleaning the heads first but if that doesn't fix it right
away, it's time for a new one.

Good luck.
