The #10 cartridge has an actual memory chip in it, about the only HP
carts with one. You can't reset it, at least not without special
equipment.

Hmmm...fair enough I guess. Anybody have any knowledge on how many
cartridges the printer itself remembers before I can reuse a previous
cartridge or does the printer write information to the cartridge and
thus it will always be programmed as low or empty? If I owned two or
three or some other number of cartridges, could I just rotate them through?

So far things are continuing to print. After getting my first low ink
warning on my black #10 I continued to print until the level indicator
software showed 0% remaining. The actual warning text says:

"The black ink cartridge in your printer will need to be replaced soon.
Replace with a new HP No. 10 Black Ink Cartridge. When an ink cartridge
is completely empty, the printer will not print until the ink
cartridge is replaced.

I take this text to mean that it will keep going until the cartridge is
finally empty. I had the cartridge refilled yesterday and after
installing it I have now printed almost 100 double sided brochures with
the warning LED flashing and the ink level still showing 0%. The other
three level indicators continue to drop slowly as my print jobs continue.

I have the officejet 7130 and my book says that the low ink warning will not
work on refilled cartridges and therefore recommends not refilling as you
will not know when it uses up all the ink.

I figure I'll just watch for the first signs of degradation in black
print quality. Once it starts to get poor I'll refill the cartridge
again. I'll harass HP and see if I can get anything out of them.

HP would probably point you to:

The Business Inkjet 1100 has separate ink and printheads. If you run the ink
out you can damage the printheads, which would then need to be replaced.

As Andrew pointed out, the #10 ink supply has a memory on the cartridge rather
than the printer. No amount of swapping cartridges will make the printer
"forget" the ink level.

The Business Inkjet 1100 has separate ink and printheads. If you run the
ink

out you can damage the printheads, which would then need to be replaced.

This cartridge (#10) is designed different than the #14, so the printhead
won't be dammaged by using a refilled cartridge even if the ink run totaly
out. The printer *knows* when the ink cartridge is empty, because in this
situation the pump works more frequent (the pump works to feed ink but when
the is no ink to feed the pump works continuously). When the printer "sees"
frequent activation of the pump, it knows that the ink cartridge is emtpy
and stop printing giving the "out of ink" message. This saves the
printheads.
The mentioned problem is dedicated only to HP printers that use the #14
cartridges, for those printers it's relly silly to refill the cartridges.
These cartridges don't have any mechanism to prevent printer printing when
the ink is run out.

As Andrew pointed out, the #10 ink supply has a memory on the cartridge rather
than the printer. No amount of swapping cartridges will make the printer
"forget" the ink level.

Older printers let you refill the cartridge once, but the ink level don't
work. I have heard that newer printers which use the #10 cartridge don't let
you consume the whole ink after you refill the cartridge, but I'm not sure
for that. Of course there is no other solution except from replacing the ink
cartridge. There are some chips, but I think they don't worth pricing.

Where then do re-manufactured #10's come from that I've seen advertised.
Have they had the chip reset?
