Looks like a Pro10s is in my future

Turn both the cart and the resetter upside down

I thought you only had to do that in Australia.

Possibly Pro10 and Pro9500 carts aren’t 100% the same size ?. My totally empty PGI-72 carts with bottom clip weight 18.0gr. Properly refilled should be around 33 gr. Exception is chroma optimizer which is 32gr. being less dense than regular colors.
I'm not optimistic at all about that resetter. I believe is kaput or it wouldn't have damaged the second PB chip.

I have tested 9500 and Pro 10 carts till I was blue in the face and I stopped refilling one after 50 refills, just to see how durable they were at standing up to regular refilling.

The Pro 10 carts are a little better constructed than the 9500 ‘s but other than that, they function exactly the same as far as I can tell, the difference in their weights are negatable.. The cart itself is not water tight (Just a Shell), only the internal bag is..

Filling these carts by weight is not necessary but if it makes you feel more comfortable doing that then please continue, because 14 ml of ink is more than enough in these carts, overfilling has other consequences as you have found.

Once filled you should be able to squeeze the cart without ink spilling out over the top, (That’s overfill) the printer will stop before the cart completely empties anyway, but Refillers normally replace carts at the low ink warning, which is a doubly safe practice..

We have always used the simple conversion of 1ml = 1gm.. so, fill by volume not by weight.. You can get a couple of extra carts from OctoInkjet and just use the chip if you wish, but I wouldn’t give up on your redsetter, just give it a good clean with plenty of Alcohol, then try it again, replacement cart are cheaper than a new redsetter..
Never is an eternity, so avoid the place if you can, and Making mistakes is better than doing nothing...

P.S. try cleaning the brass contacts on the damaged chips with a pencil eraser..

Thanks for the tips @The Hat.

I reckon that sometimes I’ve overfilled a bit my Pro10 carts, but when I remove the bottom clip, before installing the cart in the printer, I always hold it in my hand for a few seconds, letting drip any possible excess of ink (putting some paper towels below ..)
Nevertheless, in my experience, even PGI-72 cartridges not totally full, will drip a bit if you squeeze them.

Giving up on that resetter. Believe me, the pins are shinny and free from dirt/oxide and so are the chip contacts on the cartridges. I cleaned the PCB of the resetter with q-tips moistened in ethanol, until almost any trace of magenta ink was cleaned. (magenta was the cart that spilled). There’re still some traces on the solder joints of the chip and several SMD components. I did a last try today, cleaning again the PCB and trying to reset one of the PB carts. No luck. Same error.

I took some photos of the disassembled resetter so you can see what happened and why.
It was my fault, but a better design of the resetter would have prevented the issue. Just a tight seal with an o-ring or similar between the upper case of the resetter and the black plastic part where the pins are inserted would do the job, As it is, those parts don’t make a good seal at all. Any amount of liquid going over there will infiltrate inside and fall near the pins of the chip.

See on the left picture the wide black part of the casing where the ink port of the cart sits when you reset. That part is designed to retain a certain amount of ink dripping from the port but if the amount of liquid is big enough it will overflow onto the narrow part of the black channel and from there, slopping down to the aperture of the pins, will eventually infiltrate inside the case over the PCB.
In the last picture at right I tried to point out the rests of dried magenta ink. On a computer screen is not easy to tell apart from the red enamel of the PCB tracks, but if you look close you’ll see some traces of magenta on the solder joints of the bottom and right pins of the chip and also of the SMD resistor and capacitor below.
Before cleaning with alcohol, those solder joints were covered with a mess of sticky magenta grub. No wonder if it damaged the chip

A tube of toothpaste will too but not the point. The scenario is a cartridge that leaks with only gravity and not some other applied force.

Nice images!

Possibly Pro10 and Pro9500 carts aren’t 100% the same size ?. My totally empty PGI-72 carts with bottom clip weight 18.0gr. Properly refilled should be around 33 gr. Exception is chroma optimizer which is 32gr. being less dense than regular colors.
Now, in most Internet sites people are assuming that 14ml of ink= 14gr and this isn’t exactly the case. I measured the density of Octoinket Pro10 inks at 1.06-1.07 gr/ml for regular colors and 1.00 gr/ ml for Chroma. Therefore, 14ml of regular ink weight around 15gr. and 14ml of Chroma are 14 gr. Other ink brands might be slightly different but not much, I guess.

Like you, my carts declared empty by the driver weight at least 20-21 gr. I wouldn’t criticize Canon for being over cautious. Better being safe than sorry and, if we refill, no ink is lost. Of course, people using single use cartridges waste 10-15% of the ink.

Indeed, we should count 15g.
A completily empty and dry PGI-9 cart weighs 16g (without the 2g clip).
Full should be 31g then without clip.
I received many empty OEM carts and they were all 17-17,5g, so an original Canon chip leaves only 1-1,5g (could harvest one full cartridge from about 10 empty ones).
Just checked an empty resetted GY: 20g (without clip). Since I fill at 31.5g only 11,5g is used before a resetted PGI-9 chip shows empty.
There is a margin of 3,5g (wich I use from time to time by disabling ink monitoring when too lazy to change the carts), even when you refill at 30g you are safe.

Update:

Today arrived the stuff from Octokinkjet and my Pro10s is operative again, but not without some weird and unexpected issues.
First, I confirm that my old resetter is dead without doubts and so it is one of the chips of my old PB carts.
The other PB chip is most likely faulty as well, but the odd thing is that I tried resetting with my new resetter and seemed to do it correctly. Installed back on the printer, the red led light on the cart stayed on, as it should. Nevertheless, when you close the front cover and the printer performs checking routines it returns error again.

As the two PB empty carts that arrived today are fine and I already expected that the old ones were kaput, that didn’t worry me ...BUT when I installed one of the new (resetted and refilled) PB carts, then it was the Chroma optimizer cart which was reported faulty, when it had been fine until then. I swapped the CO cart with my second unit and all OK.
Then I tried to re-reset this apparently bad first CO chip, put it back into the printer and it was correctly recognized. I printed a nozzle test which came out flawless. Hooray !!

All the same, those strange happenings had put me in a diffident mod so, just to be sure, I switched OFF the Pro10s,and ON again. Guess what ? chroma optimizer was reported bad !.
Remove, reset, reinstall and good again !. Switch OFF, ON and back to faulty !.
I conclude that the chip of this CO cart is in “ailing health”, if not dying. Every time you power OFF it reverts to faulty. Wondering if anybody here has experienced this issue before ?.

Finally I have to confess that when I resetted and refilled the second set of carts I forgot again and twice to reset before refilling, Call me names !
Fortunately, following the wise advice of @The Hat, now I reset with the cart in vertical position, so any spill will fall down into the toilet papers below.
Anyway, a fool-proof system is better so I’ve sprayed both sides of the resetter’s PCB with a coat of insulating enamel (which I still had from my old days of DIY electronics ). Of course, previously I had covered the gold plated pins.

Now I’m 99% sure that, even if some ink infiltrates inside the unit, it could do no harm.
I leave the remaining 1% to Mr. Murphy.

I forgot to mention that one of the ink bottles ( mate black ) that came along with the resetter and the carts, leaked a bit. I don’t blame Martin, because the cap was perfectly tight and the bottle was sealed as well. My theory is some drastic changes of pressure and/or temperature. The bottle is now slightly deformed. Probably when I puncture the seal it will recover the original cylindrical shape

 

[palombian]

Never had this "ailing health" behaviour with the 9500 (probably the PRO-10 chip is more complex).

Only dirty contacts, cleaning both the printhead and cartridge contacts helped.

@Artur5, That was like an unnecessary trial, conviction and acquittal all in one day.. Phew..

That’s great to hear your back in the saddle again, and dabbling in and out of your refilling, but I would look again at my resetting procedure, because I reckon that might be what’s causing your early chip retirements.

There might be a difference in how those PGl-72 chip works, but with the PGl-9, I place the cart in the redsetter and wait till the red LED light comes on, I then hold that for a long second and then remove the cart, job done. (Never had a failure)

It might be that by holding the cart in the redsetter for to long could cause a power overload, leading the chip to give faulty readings later, of course I might be way off the mark here, and another thing to make sure is the chip has no moisture(Ink) on it before resetting..

All dough these chips were never meant to be reset, it’s still a bit unusual for to have several chips go bang together, one yes...

 

[Artur5]

In all likelihood, if I hadn’t damaged the resetter, nothing of this would have happened. The chips were literally destroyed by the resetter. Even the chroma optimizer chip that was apparently OK until today, might have been resetted when the ink had already leaked inside and was starting to make trouble,
All those chips are OEM, not cheap Chinese compatibles which might fail any time.
My reset procedure follows José Rodríguez advice for the PGI-72 : when the chip makes contact with the resetter pins, the led flashes a fraction of second, then it remains a couple of seconds off, turns on steadily for 3-4 seconds and then goes off, That means that reset is complete and I remove the cartridge. I’ve been doing it like this with the same resetter and two sets of OEM cartridges for nearly a year without issues, until the unfortunate ink leak accident.
