Now that I'm using the new Magenta cart in the Maxify, I put aside the old one so I could do an autopsy on it later...
I started by draining out all the magenta ink first, then removed the plastic cover to expose the inner working of the cart, and then pulled the clear membrane that was welded to the side of cart. Like a clear see through bladder..
This stuff is as tuff as they come because it was not easy to remove all of it, but I got there in the end, I don’t know what sort of adhesive they used, but I wouldn’t mind being able to buy some, its extremely strong stuff. (Probably applied with heat)
Under this clear membrane there is just a piece of opaque plastic plate that is held on by a big spring, the inside setup is very much the same as the inside of the PGl-9 cart, and the spring does the same job keeping the internal space clear when the ink is used up.

Attached under the spring is a small piece of metal that’s stuck down on the body of the cart, I removed that and forgot to take a photo, which has tiny little ridges that were underneath, it does the same job as the air vent on top of a CLl-8 cart and is the start of the internal one way air intake.

On the exterior of the cart there is a skinny opaque window strip of plastic that seems to have some ink in it, well that’s a continuation of the air intake system inside and it wiggles its way to the air intake hole (left open), this hole can be seen beside the larger ink inlet port.

The ink inlet hole is made from a stiff plastic and is covered in the same membrane that was used on the inside bladder, and behind that is a small silicone pipe which also has the same membrane covering. both get punctured when the cart in inserted.

So when it comes to refilling it’s only a matter of holding the syringe tightly against the inlet hole to get a good seal, because there is no spring or ball inside to block the inflow of ink. But you must withdraw some air first before refilling with ink.
To conclude the OEM carts are make very poorly, and can fail very easily, so it’s better to tape over the refill hole after filling to have any chance of stopping them from leaking, O’ and don’t try to over fill them, less is better..
P.S. I wasn’t going to take any Pics of the operation because there’s nothing to look at and everything is well hidden, plus it’s like watching paint dry..
