There is a misunderstanding here. The printer does not stop after a number of
prints or pages, it counts the individual drops fired. Based on the amount of
ink put in the supply and the individual drop size the printer can calculate
how much ink is left. There is some margin to keep the supply from running out
and introducing air into the printhead. Allowing the printhead to run dry
would result in damage to the printhead.


From your article, it appears there are three dates of concern:
"... the date printed on the ink cartridge is not the expiry
date [which] is determined either by a cartridge being in the
HP printer for 30 months, or the cartridge is 4.5 years old,
whichever comes first. The date on the cartridge, which you'd
every reason to think was the expiry date if you didn't know,
is 2.5 years after it was manufactured."

Therefore, the 3 Hewlett Packard ink cartridge dates appear to be:
- The date the cartridge was manufactured
(+ 2.5 years = printed date).
- The date the cartridge expires
(death occurs on the printed date + 2 years)
- The length of time the cartridge is in the printer
(2.5 years maximum)

Given the date printed on my HP c5010a tri-color ink cartridge is:
- 2004/06/10
(deriving an HP ink cartridge manufacture date of 2001/12/10)
And the date printed on my HP c5011a black ink cartridge is:
- 2004/04/29
(deriving an HP ink cartridge manufacture date of 2001/10/29)

This would seem to indicate the true HP ink expiration date is:
- 2006/06/10
(HP c5010a tri-color ink cartridge true expiration date)
- 2006/04/29
(HP c5011a black ink cartridge true expiration date)

Hmmmm .... so my HP ink cartridges are NOT expiring after all!
Then why do I see officejet d145 "Black ink old. 8 days to expire"
& HP OJ d145 "Color ink old. 8 days to expire" error messages?


The expiration is the *earlier* of 30 months from date of insertion into the
printer or 4.5 years from date of manufacture. The ink supplies are cheap
compared to the printheads, and the expiration is enforced to protect the
printhead.


Assuming the true HP ink cartridge expiration date is two years
hence, the HP OfficeJet d145 must be calculating the 30 months
in service expiration date instead. Now the HP error messages
begin to make sense.

Given I was presented with the HP OJ d145 printer as a birthday
gift from my lab mates in January of 2002, we calculate:
- 2002/01/14
(the 30 months in-service HP expiration date is then 2004/07/14)

That is, the 30-month contigious service date is what the HP
office-jet d145 printer must be complaining about!

So it's NOT the printer cartridge which is expiring; it's the
HP 30-months continuous service barrier which is hurting me.
I still have until 2006 for the HP ink cartridges to expire.

How can I recover the two years I am entitled for these cartridges?


The printer is designed to allow an ink cartrdige to be in the printer for 2.5
years. There is not an "entitlement". Once the seal of the supply has been
broken and the supply installed in the printer you have 30 months to use up the
cartrdige. Over time normal vapro losses will cause the ink to thicken and
become less suitable. Once again, the printer limits the allowable age of ink
supplies to avoid damage to the semi-permanent printheads.


Someone kindly emailed me this link which describes HP ink
rotation steps:


http://www.alotofthings.com/supportf...010A5011A.html

"Since Hewlett Packard multifunction printers only retain the
information of the last two cartridges, you can alternatively
swap cartridges in and out. This of course requires that you
have a total of three HP ink cartridges that are not date expired."


This applies to the low on ink indicator in the printers with integrated
cartridges containing both the ink supply and printhead. In these pritners the
toolbox and printer will indicate a low on ink condition but will not stop
printing, since there is not an external printhead to protect there is no need
for the pritner to limit printing in this case.


Do HP printing experts have any other suggestions to overcome
HP OfficeJet d145 printer ink cartridge expiration messages?


Put a fresh ink supply in the printer....

The HP printers with separate ink and printheads are designed for relatively
heavy usage home users or small office applications. If you do not print much
you should probably get a different printer. The PSC 2210 or 2410 or Officejet
6110 may be a better fit for your needs.

Thanks Bob for a thorough explanation of the expiration dates. I at
least understand the purpose of the expiration dates on cartridges and
printers with the built in print heads. makes too me. That helps
explain a few things to me. I appreciate your Relpy. Stu

You are welcome. I may not have made things clear for the case of the
cartridges with built-in printheads. These cartridges have an "install by"
date printhead on the package and a "warranty date" printed on the cartridge
body. The integrated print cartridges do not have an expiration date and the
printer will not stop printing because it thinks the cartridges are tool old or
too empty.

I'm pretty ****ed about the 2 HP printers my mom (win 98) has had -- the
last one started printing purple 3/4" color bands at random times and
now prints all photos with a purple cast, although text printing in b+w
and colors comes out fine. She's printed 1500 pages, which sure doesn't
seem like a proper lifetime for a printer.

It sounds like she has a cartridge that is running out of yellow. Text is a
very low duty cycle of printing compared to photo printing. A cartridge that
still ahs a bit of yellow ink left could print colored text OK but fail to
deliver enough yellow when trying to print graphics.

What is the mode of the printer? Most likely a fresh color cartridge would
solve the problem.

It's an 882C. When printing a photo it chugs along properly for 3" and
then prints a 3/4" band of photograph with a distinct purple cast. Then
it goes along properly for another few inches (these distances are
pretty much random) and then prints another 3/4" band. Sometimes it
will print a whole photo properly, sometimes with one band, sometimes
with two or three. Occasionally it will print an entire page with one
of the rows of dots lagging behind, which really looks cheesy. This may
have stopped when the cartridges were replaced last time, but perhaps
not.

A third failure mode: consider a photo of a flat wall lit from one
end. The wall will shade evenly from light to dark across the picture,
right? That's what happens most of the time. Every once in a while,
such a picture will exhibit stair-stepped blocks of color, as if the
resolution were suddenly cut to 1/4 or 1/8 the proper value. Especially
annoying when it's a person's face instead of a smooth wall or the sky.
A second attempt at printing the same picture may or may not print
properly. Likewise with the purple banding. All intermittent.

What is the mode of the printer? Most likely a fresh color cartridge would
solve the problem.

This happened both before and after replacing the cartridges. I doubt
if the new one (third set of cartridges, possibly) has printed more than
100 pages. Went through the test process, cleaned the print surfaces
with a damp Q-tip per instructions. No difference.

What do you mean 'mode'? If you mean draft/ordinary/high-res, she
prints 'ordinary' because 'high-res' takes longer but makes no
difference discernible under 10x magnification.

It's called posterization. It happens when you decrease the number of
colors. Sounds like time to write the printer off as a lost cause and
find something that works reliably.

What really bothers me is that HP is supposed to be the gold standard.
This printer was $300 or so when she bought it a couple of years ago.
Everybody is always happy with HP and says they're reliable. So how
come she got so unlucky? The previous one just stopped working a few
months out of warranty.
