I've heard some (inkjet) cartridges are touchy about how well
you reseal them after refilling.

Some are terrible. The 940 is great in that it uses a rubber BB to
plug the hole from the factory - I replace it with an 8-32 panhead
screw.

Ha! What's the problem with a "bad seal" after a refill? Does it cause
the ink to *run* out of the printhead (atmospheric pressure)?
Yup. That and they leak all over the place before you get them into
the printer. If you get air into the bag, and the air gets into the

"Bag"? I guess that means there's a "bladder" inside the cartridge?
I.e., it's not just a "plastic box full of ink"?

On the 940 you have a sealed bladder

printhead, it's bad Jiu-Jiu too. There is a tool to "bleed" the
printheads, but it's messy and wastes a lot of ink.

Filling the "tank" I take out the BB or screw, inflate the bag with a
modified "canned air" duster, then inject the ink with a syringe. When
full I re-install the screw, then draw any air and a bit of ink out
through the ink outlet.

?? "Outlet"? Meaning nozzles? How do you coax the air out -- turn it
upside down? (nozzle side up)

Not nozzles - the "tank" has a "quick connect" fitting on it that
connects to a flexible nylon? line that feeds the ink, via another
"quick connect" to the printhead. The tank just sits at the corner of
the printer while the printheads fly back and forth - - -
I've put well over 25 liters of ink through
those Pro 8000 printers over the last 5? years - and that's not
counting the 70? new cartridges we've put through (along with a fair
number of print heads)

I dunno. Sure seems easier to just print with lasers...
Not when you need colour. Yes, we also have 2 big colour lasers in the
office, but printing insurance liability slips on the laser isn't a
really viable alternative - and draft mode on the inkjet is a lot
cheaper than using the laser - both in ink and power consumption. We
also have payment notices/renewals emailed in that get printed off
overnight for processing. We did use an Oki LED printer for that for a
while, but went back to the officejet because of the power used
heating up the fuser every 20 minutes or sa as the emails came in.

At $4 to $8 per ounce for the ink, it is actually cheaper than toner
for the laser too.
