All new compatible chips for OEM 551 Carts !

I decided to pull the paper chip from a 551 cart to see what it was made up of and how easy it was to remove it.

It’s almost impossible to get them off without tearing them as I did with my first attempt, but after finding out how crafty Canon were, I managed to get the third one off in one piece.



Canon have put a sealant on the underside of the chip and then cleverly placed a plastic pillar in a position that will tear the chip when attempting to remove it.

There is quite a big grove (Hole) behind the chip so I went looking and found that the Chinese have made chips that will now fit onto these OEM carts.



So if you don’t want to use compatible carts you don’t have too but it would be rather expensive to get all new XL OEM carts and then the chips just to be able to use the OEM’s, I reckon it’s cheaper to use and refill the compatibles..

Looks like Canon is going HP way (type 364 ink tanks)
Perhaps it is possible to cut off plastic with chip on it
BTW another example of superb field depth in CCD scanner

I am new to this and just purchased a kit from Precision Color. They recommend replacing the Canon yellow cart with a brand new cart then changing the chip from the old Canon cart to the replacement cart. Do you think I will encounter this same problem? I have a Canon Pro 100.

Not at all. You carefully trim off one of the dimples ( the one that's in the closed hole of the chip. The other one is opened on the side ) and then slide the chip out laterally. To swop to the CLI-8 Yellow cart ( or any other purged and cleaned color CLI-8 cart ) just reverse the process. I put a bit of double stick tape on the back of the chip to help secure it in place.

Changing the yellow CLl-42 cartridge for a CLl-8 cartridge is so simple all you have to do is swap the chip from cart to the other here is a link to how it’s done.

Looking at how simple that circuit is and how easy the few components are to remove i reckon a friend of mine could etch circuits onto thin plastic and use the components from the old paper chip on them (if you have ever ripped apart a old keyboard and seen the plastic membrane under the keys you will know what i mean).

In fact depending on how deep the hole on the cart is we could all probably do something similar with copper plate or thick materials, along these lines...

I wonder if there is anywhere on the net hidden away with the code to the chip? I guess it must be out there somewhere considering there are auto reset chips now. Get hold of that and if the chip is re-flashable you could probably ghetto hack your own auto reset chips also........

Yeah yeah i know hard work out of the realm for most, but could be a fun experiment for those that like to tinker

Replacement chips would be far easier and you then can spend the time PRINTING..

Well yeah lol you can buy refill 551 carts now with auto reset chips for not too much cash, so i agree entirely 100% not worth the effort. I was just pointing out its a pretty simple circuit i would not even be shocked if you can draw it small enough (find someone with tiny hands lol) that you could draw that circuit out on paper with a pencil and providing you could somehow mount the chip and its few resistors have it work.

Im not advocating anyone should bother trying more a case of a observation of what could in theory be possible.

If i had etched circuits before i would probably give it a go just for a laugh, and then fail and go and buy some refill carts with chips lol.... Yes i know i must bore easily
