Hi,
I am quite sure that you can sub an HP 15 for a 45 but not vice versa.
So, the answer to your question is, no.
The physical configuration of these two cartridges is identical. Can't
you buy the higher capacity 15 (for a gazillion dollars!)?
Why don't you consider refilling to save money and then you can refill
to full capacity as well. We now have a bottom fill tool that refills
directly thru the printhead and makes refilling this cartridge a snap.
Here's a picture of the tool in use:

If you have a printer that requires the #15 cartridge (81x, 84x, 916,
920, 940), then you are out of luck. They will not accept the #45 due to
some slight electical difference. Somebody figured a way to sort-of make
them work by blocking one of the contacts, but it also causes some nozzles
to be disabled.
If you don't mind refilling, you can do that. I think the #15 can hold
nearly as much, if not the same, as the #45 physically.
The same issues affect the #17 (low-capacity version of #23.)

US patents 6,332,677 and 6,325,483 go into great detail about the 600dpi
1/2" cartridge (i.e. the #45) and a cartridge ID system, respectively.
It appears that the same 22 pins that are used to select banks of 14 ink
nozzles, are also used to select a 22-bit ID string that is read out through
a single "sense" pin. By taping over certain address pins, it is possible
to spoof part of the ID string, but also disable 14 ink jets.
I did not investigate in great detail, but I believe (I'd love to be proved
wrong) that there is no way to spoof a ripoff printer into fully using the
#45 by just taping over contacts. I think it takes active circuitry to
emulate the 22-bit ID string that the printer expects. An empty cartridge
would provide the necessary circuitry, and could (in theory) be installed
"under the hood" and wired into the printer's circuitry. However this involves
extensive tinkering and I'd probably wreck my printer before I got it working.
In practice, you just watch your local buy/sell newsgroup. The one here in
town yielded me an 850C printer (which can take the #45) for $5 (I had to
clean it, it was full of crud from leaky refilled cartridges, but it works
fine) and I recently saw an 812C go for $50. The 812C requires the #15
cartridge, but is still a heck of a lot better than my 842C, which also
requires the #17 colour cartridge which is the biggest ripoff of all.
I wrote a rant on my web page when I found all this out (before I had found
the patent documents):
http://www.geocities.com/mwandel98/printer_ripoff.html
I also have some pictures I took of a disassembled #45 cartridge on my own
server machine...
http://wandel.dyndns.org/hp45/
Unfortunately I don't have the equipment to take good microphotos of the
(really quite marvellous) print head IC. The patent tells all you want to
know about it though (27 drawing sheets).

To each their own opinion. Having taken apart a #45 cartridge and
gotten a pretty good idea how it works, I'd say if you're not capable
of cleaning up a messy crud-filled printer, you probably shouldn't
try to refill cartridges either. Neither thing is easy. Anyway
a properly refilled cartridge wouldn't leak like that.
The #45 has a tricky spring arrangement inside that causes a slight
negative pressure (i.e. suction) at the print head. If refilled and
not sealed absolutely airtight, this suction will not be there, and
there will be nothing to prevent the ink from leaking out gradually.
Also since the cartridge is filled from the bottom, if the fill opening
is not airtight the ink will leak out there as well.
I have my doubts about refilling too, and I think I can afford the price
of full #45 cartridges. It's just paying as much or slightly more for
half-full #15 cartridges that really gets my steam up.
Moreover to answer those that have high-capacity printing needs..they
might be advised to visit Kinko's once-in-a-while and spare their inkjet
all the wear-and-tear.....
Home printers are designed for low volume typical home use....if one
does - that much - home printing that they can save hundreds and
hundreds of $$$ over time by refilling then I submit they can save even
more by farming out the work....

After refilling the first one or two, it becomes quite easy. My technique
is to refill from the bottom fill hole and to use a stainless steel set
screw to seal the hole. I then use the Snap & Fill to remove any air in the
cartridge by pulling a vacuum while the cartridge is inverted. This also
helps equilibrate the pressures in the bladder so that it will not drip. I
also place a bit of aluminum duct tape ove the refill hole and set screw for
extra measure. A refill only takes a few minutes.
The cartridges work great with a quality ink and the cost goes per cartridge
use goes from $25 to about $3. The HP #15s can be filled to the full #45
capacity; one just needs to ignore the empty cartridge warnings.
One comment I will make is that I have not found a refill ink from any
vendor that is quite as black as the original HP ink. This is not an issue
on photo printing on photo paper as the black cartridge is not used.

Hmmm. I got my copies for free. When you view the text portion of the
patent, there is an "Images" button at the top. Click that, and, at least
with a browser that can display TIFF files inline, you can then page through
the 300dpi scans of the pages.
On my Linux setup, the plugin didn't work (I only saw the upper left corner
of the pages, with no way to scroll or zoom them) but the whole TIFF file
ended up in the browser's cache. So I just paged through, collected all the
TIFF files from the cache directory, and printed them using tiff2ps.
Looks perfect.
Charles, I wish you had told me sooner. Since you seem to be the only
one with the knowledge, I think it is your responsibility - your duty

The problem here is your reference to ethics and morality. I respect your
opinion that it is not a good idea to fill cartridges. This has nothing to
do with ethics and morality. Perhaps you need to define these terms because
others and myself don’t seem to share your definitions of these terms. Just
because the cartridges are not “meant to be refilled” does not mean they can
’t be refilled or there is anything wrong in doing so. Read up on
recycling. You will be amazed at how people have helped the environment and
saved money at the same time.
I have been a loyal HP user since 1991 when I bought a HP IIIP laser. Up
until last year I only used brand new HP toner. The price went up to $90
and I decided to try a refilled cartridge. I got one for $27 and it has
printed better than the new HP toners I had been using. Even sent the old
one back for refilling. How was I immoral by using a refilled cartridge and
not having an empty take up space in a landfill? Anytime we can recycle, we
are doing the right thing. Saving $63 was an added benefit.
I also have a HP inkjet. I now am starting to try the refill these
cartridges and the results have been very favorable. I believe that HP is
wrong in not recycling these cartridges. When you refer to the greed of
refillers, don’t forget HP. Fifty cents worth of ink for $30 sounds very
greedy to me. But as the saying goes ”There’s a sucker born every minute”

Furthermore you continue, as others do too, to harp on the "HP greed"
bandwagon (to justify your tactics)saying things like $.50 worth of ink
for $30. Neal you and I both know you are paying for a lot of high-tech
savvy in those smart HP carts and not just for the ink alone. Do you
have any idea yourself how to manufacture a working ink cart for your HP
ink jet printer? It takes a helluva lot more than a syringe and a
bottle of cheap ink.
Lastly, just because something "can be done" is not justification for
it's implementation.....you should know better. That kind of "proof"
only convinces grade-schoolers and those with comparable education
levels.

Ever use a screwdriver for anything other than driving screws?? Maybe open a paint can or pry something open? If so you must be unethical and/or immoral when judged by your own standards.
You buy a product and it is yours to do with as you wish. You can smash it with a hammer, or use it as a hammer. If using it in a way not intended by the manufacturer voids its warranty, so be it. It's the purchaser's choice. If using a product in a way not intended by the manufacturer results in an injury to the purchaser, the blame lies with the purchaser (or at least should be). We are not talking about software licensing where you do not really "own" the product, in which case your argument may have some validity.

Refilling cartridges is not "something for nothing." The supplies cost
money and there is actual work (with some skill) involved in refilling the
cartridges. It takes maybe $3.00 in materials, 5 minutes to refill and
another 5 minutes to clean up (assuming no accidents with the ink). Your
choice is to not refill cartridges; you value your time otherwise. That's
okay. But what I don't understand is your hostility towards those who do
refill cartridges.

Why not just use the snap and fill to refill? The set screw does work
best for refilling thru the fill hole. But you have to make sure you
give the cartridge a little squeeze when sealing so that the pressure
will equalize.
I like the snap n fill to refill because it flushes the printhead
nozzles and we think allows the cartridge to last longer without ink
building up.
There are two levels of HP ink availble. One is more pigmented (more
water resistant) but not as rich a black. The other is less pigmented
biut the black is much richer. Check us out next time you need ink.

Hi,
Really? I've always liked the bottom fill for these pressurized
cartridges - I think. I don't ever remember having anything against them
but this business is always a learning process. MAybe I wasn't that
familiar with the bottom fill then and was just promoting what I knew
worked.
I would use them for one reason alone - that is because it flushes the
printhead and helps dissolve any dried ink. I keep trying to get my
suppliers to make these for all black cartridges.
Here is a view against bottom nozzle filling by a refiller
snip>
With many years developing ink for ink jet with patents and processes behind
me, I recommend not to fill through the nozzles of any Ink Jet. There is
several good reasons for not filling like this. It should be obivious that
the OEM does not do this for good reason.
If there is a fill hole use it. Any machine that fills through the nozzles
such as the "thing from colorado" did (hopefully they changed it). It forces
undo pressure on the print plate and possibly delaminating the integrity of
the nozzle chip assembly, either through excessive damage to the resisters
and or warps the head. Probably the most evident damage will not occur until
your customer recieves it or leaks during shipment. Really that is where and
when you will enjoy repeat business or not. Why can I make this statement?
How can I be right. well you are forcing a pigmented ink system into and
through the nozzles. Pigment and carbon black and some binders are abrasive
in there natural state. Imagine it being like sandpaper, When the ink is
forced you can degrogate the nozzle oriface and simutanously cause bad print
quality and micro scopic air entrapment in the ink and cause eventual
outgassing over the screen and nozzles where bubbles form on these surfaces
and thus your customer will yield simulated clogged nozzles when in fact it
is the air entrapment at fault by improper feed manifesting starvation. Is
there a way of correcting this?
well yes but through the expense of major investment of money for degassing
equipment and Special X ray devices for inspection. When in fact if you had
filled through the fill as the OEM and with a slightly reduced fill time the
air would not form.
Another sure tell sign of excessive pressure in the cartridge is why do my
45 or 15's or other Air bag systems leak after I tape. If you experience
this and you know with out a reasonable doubt your taping procedure is
credible, I would have to say the cartridge has exessive pressure.

Well, I thought you had, and you didn't offer a bottom fill
at the time. I remember one of your competitors was very
adamant about not filling through the nozzles because of
probable wear by the pigmented ink. I thought you had
completely agreed. Oh well, getting older. But I'll
probably order from you anyway if I decide to start
refilling cartridges.
I have not refilled a #45 more than 4 times. I have a ready supply of
empties and when I cannot get 100% of the nozzles firing, I recover the ink
back out through the fill hole and discard the cartridge. When I have only
a few nozzles bad, I have often been able to recover them by putting Windex
on a folded up paper towel and gently blotting the nozzle plate of the
cartridge against the moist towel. I have also used the Snap & Fill to
vacuum some of the ink out of the cartridge as a way of flushing out the
blockages.

The #78 color cartridges have been more problematic for me. I am coming to
the conclusion that these cartridges are very particular about the physical
properties of the ink. The #45s seem to work with just about any vendor's
ink but the print quality varies. The #78s just don't seem to work right
with some of the inks (all supposedly produced for the #78) that I have

My experience with refilling cartridges with the Snap & Fill has been that I
have seen a higher percentage of nozzle failures this way. I strive to have
all of the nozzles working. I have refilled cartridges with the Snap & Fill
that were working perfectly before the refill and had around 20% to 30% of
the cartridges with a few nozzles no longer firing after the refill. My
guess is that I forced some particles into the nozzle holes or damaged the
nozzle plate by refilling too quickly.
By refilling through the fill hole, I have not seen this problem. What is
great about the Snap & Fill is that I can use it to pull the air out of the
cartridge and equilibrate the pressure of the bladder bag. I usually pull
several milliliters of ink from the cartridge which also flushes out the
nozzles. Refilling through the fill hole without the Snap & Fill to remove
the air and equilbrate the pressure in the bladder was alway messy. I would
have to let the cartridge drip for a while before putting it in the printer.

I have tried a brand of ink that is similar to this description and found
both types a little more gray than the OEM ink. I also thought the
viscousity was off as I noticed more bleeding into the paper fibers of paper
not specifically formulated for ink jet printting. I don't know if this is
the brand that you are selling and it was about a year ago that I tried this
brand of ink with two variations for HP printers from a local vendor at a
MarketPro show.
I'll check out your web site.

Here i rest the #78 on tissue pad in a plastic cup I also use the overflow
hole trick 3 holes 3/32 dia 1.375" from the top into each chamber at the
front so overfilling is avoided.
Finally I use the INKTEC balance clip to remove a few ml's of CYM ink and
air (Inktec ink www.intec.com from Korea )but there are US suppliers.

I use a tool that I purchased from http://www.theinkexpress.com called the
Snap & Vac. It is similar to the Snap & Fill but pulls a vacuum on the
bottom of a #23 / #78 cartridge. I have had moderate success with this
tool.
Here's the phenomenon that baffles me. I can take a perfectly good #78
cartridge with all nozzles firing. Before it is completely empty, I inject
5 ml of ink into each color into the bottom with a long needle. I am always
careful not to inject any air. What often happens is that one of the colors
will act as if there is a partial blockage when printing. All colors of the
ink flow freely when blotting the nozzle plate on a paper towel but when
printing, it acts if there is air or an obstruction to the ink flow path.
Running a nozzle test will show a number of nozzles not firing but not the
same ones each time. The phenomenon is more prevalent in draft and normal
modes of printing (faster speed). Any ideas?
