Tricks to jumpstart generic ink carts?

I find the HP carts last about two years before some thing
goes wrong. The
My experience has been that cartridges tend to die more because of a
lack of use rather than extended use. Once they clog, the don't want
to open up. I've soaked them for days, blasted them with compressed
air, etc. It's all a stop-gap once they clog. Occasionally I get
lucky and one works again for a while.


Skillet with enough boiling water to cover just the print head.
Best to suspend with tongs rather than rest on the bottom of the
pan, though I've done both. Let it slow simmer/boil for around
five minutes. Periodically lift and squeeze the sides of the
cartridge to see if your ink has finally begun to release and
flow. Yellow is often the most resistant, and usually the biggest
problem maker. On cartridges that cannot reclaim the yellow, yet
still have the other two wells working? Whenever possible, try to
plan for some large runs of magenta tinted or blue colored flyers
(brochures, or downloaded manuals, or whatever) to use them up
before switching out cartridges. Lots of crap we print isn't
color dependant at all. It smarts far far less whenever dumping,
if that 2/3rds remaining ink actually gets itself used for
something beyond just profanity fodder.

My longtime romance with HP has come to an end. Still own a
perfectly functional 882 and a drawer full of new cartridges, but
enough is enough. I'm fed up with their melting clogging drying
inks, and their wasteful pricey cartridges with so many inherent
problems and failures. So it's good-bye HP, hello Canon, and its
no looking back.

The JQ Refill kit I have comes with a holder for the cart....

This has a rubber seal to protect the head. You fit the cart in the holder
and connect a syringe. First you suck out all the air and any remaining ink.
Then you fill the syringe and reconnect it. It seems to be important to fill
the cart a slowly as possible but that's the only precaution. The cart spec
says 42ml but I usually refill it with about 20ml.
I have a similar kit with a jig to mount the cartridge. I hadnt
thought of draining out the existing ink before filling. Is there a
benefit in this?

I'm a bit worried about using the jig to suck out ink. Surely a print
head designed to deliver picolitres will be damaged when several ml is
pulled through quickly?

Sorry for the delay in replying...

I find it hard to get all the air out without the remaining ink coming out
as well. I don't refill a cart until it's showing signs of being empty so
I'm not sucking loads of ink out.

Possibly although my carts seem to last about two years. I remove/refill as
slow as possible.
