I am using the HP black ink cartridge 45 and tri-color cartridge 78 for HP
Deskjet 970cxi printer. I am sure there are inks still inside the cartridge.
When I shake it, I can hear ink still inside the cartridge.
Because I bought it less than 2 months ago and I only print around 3 pages
per week max. But the HP printer orange ink light keeps blinking.
When I run HP Deskjet 970 Toolbox, the estimate ink level is 90%
Priming the cartridge is not your problem, the
machine can't know anything about priming.
The 970 doesn't know anything about the ink level
in the cartridge, it just estimates the amount
that should be there based on printing. If you
refill a cartridge and put it back, the machine
can't know that without you going through special
procedures. You report that your refilled it and
your cartridge says 90 percent full. Unless you
went through some process to set the cartridge as
new (full), that doesn't make sense. The toolbox
would continue to report the ink level that
existed before you refilled it.
Refilling the 45 is easy, but you should use a
tool that fills through the printhead. That way
you don't get the ink in the right place, don't
get bubbles in the cartridge or have problems with
priming.
Back to your problem, when you open the top cover,
where does the yellow arrow point? Problem with
black cartridge ( dot for black and a frown face)
or low ink (dot for black and a low ink level)?
Since the tool box say 90 percent full, it can't
be the latter. If it stops at the former, that
can mean the cartridge is missing, improperly
installed, wrong cartridge, or cartridge defective.
If the contacts are corroded or unclean, you can
gently wipe the contacts with distilled water and
reinsert. If that doesn't work, The cartridge is
probably have damaged.
My 970 with a (42ml cartridge) lasts for at least
1 year and will print hundreds of pages. Even if
you have the smaller quantity black cartridge you
would not run out of black ink printing only 24
pages (your estimate 2 months x 3pg/week). Time
to buy a new cartridge probably, or maybe your
used printer has a problem.
