Do Canon Setup carts contain less ink?

[Smudger]

A non-scientific experiment.

Equipment:

4 x Canon 551 'Setup' carts from a new MG5650 printer
4 x Canon 551 Chromalife 100+ replacement carts
1X Chinese digital scale.

The 'Setup' carts each weighed 25.1 grams with the cap and vent tape in place.

The Chromalife 100+ carts each weighed 22.9 carts with the cap and vent tape in place, and appeared to be of identical construction to the 'Setup' carts.

Both carts are opaque so what is inside is a guess.

Either there is 2.2 grams more ink in the setup carts, or the construction is different. The ChromaLife tanks each contain 7ml of ink, according to the packaging.

So, is there a difference in ink quantity between Setup carts and OEM standard carts?

As a wildcard; a no-name Chinese compat 'XL' cart weighed 24.7 grams

You got it in one, they are different on the inside, you can see by the Pic below that the setup carts have a dividing wall to deliberately make the setup carts smaller than the XL carts, which makes for the huge difference in capacity..

Cripes!

"Tricky" on two accounts - first, the deceptive packaging for the setup cart. Second, 7 ml. of ink - considerably less than the bci-6 carts I started with 11 years ago that, as I recall, have 13 ml. of ink. At least the nominal prototype of the "sell the sucker the starter cheap and then hit them with the cost of disposables" business didn't make the razor blades smaller and less productive with new iterations of the product!!

Cripes squared.

The capacities of CLI-x51 cartridges have been discussed before. See this thread and this post.
