We are using Hewlett Packard Deskjet 970cxi printers in our office.
This deskjet requires both color and black ink cartridges with ink in the
printers for it to work.
However, we ONLY use the black ink to print office documents.
We are using the Windows XP and have set the printer property preference to
print in Black only (Advance - Color).
We found the color cartridges still being used and in time its empty and
requires to replace with new ones.

Can you tell me how to either disable the color ink cartridge ink level
sensors or disable to software to use any color ink at all?

We do know HP is getting rich selling us those expensive color ink
cartridges.
Your advise is much appreciated.

I don't think the printer will stop completely. It may complain that
you're out of colour ink, but it should still print. Make sure you leave
the empty colour cartridge in the printer though.

Just keep printing and ignore the complaint from the software that
you're out of colour ink.

In the printer driver, there is an option for "grayscale" printing. That
should use only the black cartridge if you have a usable colour
cartridge installed. You may also need to use the "plain paper" setting.

My HP 970 needs a color cartridge to print but the
cartridge doesn't have to have ink in it. If you
rotate 3 color cartridge through the 970 (put it
in, let it do the test print, put the next
cartridge in, etc.) it will think the last
cartridge is full so you won't get low ink
message. End of problem.

Don't forget that the printer goes through a headclean cycle at start up,
sometimes when powering off the printer and at set times during printing.
You cannot alter that procedure. This will cause your ink cartridge to empty
even with no colour printing. However, as each cartridge has the printhead
on it, you can leave an empty one in the machine. The printer should
continue to work normally, setting it to grey scale is a useful suggestion
many printers use blue ink with the black to produce a true deep black.

Yes, I confirm the HP Printer setting are:
Color: Grayscale: Black only
Paper: Plain paper

But with this setting, with both color and black ink cartriges installed at
the same time, the color cartidge will be used up almost 2 months before the
black cartridges.

Can you tell me how to disable the color cartidge ink level sensor?

This sound good idea.
Can you explain how?
I understand everything the ink cartridge is removed or power on, HP deskjet
printer will perform ink level checking? or, may be I am wrong?

The 970 assumes that any new cartridge is full and
it also remembers the last three cartridges. So
if you are using cartridge A, then you put in B,
then C, then D, and finally A, the memory of A
being out of ink will have been lost and it
assumes that it is a new, full cartridge. I think
this is the easiest way to reset the memory but
you need save three old (a total of four ) cartridges.

BTW, there are two other ways to reset the
memory, one involves pushing the front buttons and
the other is taping the contacts I don't have
that info in front of me but it has been well
documented, so you should be able to find it with
a google search.

Why don't you simply use a laser printer? Ink jet printers are not cost
efficient for printing large volumes of text documents. Laser printers are.
You can get a good laser printer these days for about $150.00. A basic
cartridge will print about 5000 pages and cost about $75.00. Get a laser
printer.

It only remembers 2 cartridges of each type (currently loaded and
previous). You only need to rotate between 3, not 4.

I don't think you can reset using the buttons. That does let you
access diagnotic printouts and similar. The taping method just alters
the ID, giving the effect of changing cartridges.

This doesn't make sense. I go through 2-3 black cartridges for every
color, and I'm NOT set to black-only printing. I always use the hard to
find 78A instead of the common, half-full, 78D. I also assume you are
using the full 45A and not one of the low-capacity versions?

As others posted, if you only want black printing, get a laser
printer. It's cheaper in the long run.
