Experiencing more problems with Canon CLI-8 yellow cartridges

[pharmacist]

I do reset and refill alot of Canon PGI-5Bk/CLI-8 cartridges and I can say the CLI-8 yellow are giving me more problems than everage. Until now I've got 8 faulty chips of which 5 of them are CLI-8 yellow, 1 CLI-8 cyan and 2 PGI-5Bk. Is this normal or do other people have the same experience ? Now I've got 1 yellow cartridge which is not faulty but I am not able to reset it (yellow exclamation mark saying ink is running low).

I've reset around 30 so far, had one Cyan fail in a clients printer, but it was a new OEM, not one I reset.

How does one "RESET" the canon CLI cartridges? I have refilled a couple and the Magenta worked for a bt but had the ! all the time. The other cyan is doing well. I am using canon cartridges and refilling them.

there are several threads which answer your question, this is a good starting point:-

pharmacist,

So far I have had 3 yellow cli-8 that where faulty, each of them bought over the last month, the printer would not recognise them, 1st one I got localy and had it replaced only to find the replacement had the same fault so got a refund. Went to another store and had the same problem, replaced cart worked untill I refilled and it would not reset. now I have have a yellow and black cli-8 that wont reset. When I say wont reset, it flashes once and then lights up in the red setter but the printer sees it as a faulty cart a 'problem with the cart mesasage pops' up.

The faulty black cli-8 was one of the oem carts that came with the printer and was the first I tried to reset, thought it had reset too but it still throws up error messages.

So there is a higher risk in resetting cli8-y cartridges. Whenever a printer reads the chip it will check the integrity of the data in the chip, such as checksum, total number of bytes, bits or whatever. Perhaps the resetter has some glitches in writing (resetting) cli8-y chip. You lose some cli8-y cartridges as a result. Unless the resetter can correct it by resetting it again to pass all those integrity check the cartridge may be lost forever. This may be a concern to think about when buying a resetter.

Today I tried to reset this cartridge again, but no way: it blinks a few times when put into the resetter. When back inside the printer it still shows the message:

Printer is online.
Ink is running low. View the ink details

The usual yellow exclamation icon is placed above the yellow cartridge.

Conclusion: even with resetters the chipped Canon printers are to be avoided. Never did I have any problems with my Canon i9950 and MP780 printer before. Those printers are reliable even with aftermarket cartridges: you will get accurate ink is running low warnings by the optical detection system of the cartridges. I can even put these faulty yellow CLI-8 cartridge in those 2 non-chipped printers and it will say: cartridge is full. What the hell with this chip on those CLI-8 cartridges ? Nothing but trouble on the long and sometimes even on the short term......

Hmm, maybe there is a batch of new chips on the market which can not be reset with those commercial resetters......

Food for thought, The black cart that I have and is un-resettable was one supplied with the printer, the yellow carts I had that where faulty where new ones, not ones that have been in service and refilled and reset, on the face of those facts I have experianced, it seems like the chip is the problem. I did contact canon Uk on this matter and was advised to change the cart, no mention of exchanging it at the shop /store.

I did take the yellow CLI-8's back and had them exchanged and the store assistant mentioned they do sometimes have to replace them from time to time, indicating that sometimes the chips can be duds.

So far all the working carts I have reset have done so without a problem but like most semiconductors I wonder if they are sensitive to static and may be carefull handling should be used. That said, I have washed out about 6 assorted CLI-8 carts with the chips attached to no ill effects, yet. There is a lot of plastic material making up the cart and printer as well as a resetter casing, as well as the bag the cart is supplied in, this could all conspire to build up a static charge. So it could be how the chip is handled, what the person is wearing or even how you look at the dam thing that could pop it. I wonder if using one of those anti-static bags motherboards are supplied with as a working area for refilling would make any difference to the life of a cart and its chip.

Martop,

About static electricity: HP with their latest HP 364 cartridges which looks very similar to the CLI-8/PGI-5 cartridges, are chipped just underneath and are protected with the orange caps and can not be touched until the orange caps are removed and this guarantees that chip failure/DOA is kept to a minimum, unlike Canon's design, which is more prown to static electricity during transport in that plastic bag.

I wonder if there is any information on the part number for the canon chip or a spec sheet for it, just to see what the handling precautions are. Untill that day arives I think I will take antistatic measures to preserve what carts I have.

Have took a look at the new HP carts on druckerchannel, The chips look very similar to canon's I see your point about the orange cover protecting the chip. I wonder if HP's chip is embedded into the case or just fits flush to the base of the cart. Never seen the new HP carts till now, looks like they copied canon for the carts and the print head.

I never understood canon's idea of sticking a cart in a plastic bag that on by the looks of it, is not antistatic.
