ConeColor in P600 - do I have the right refill carts?

[eburden]

I recently put a new P600 in service as a color machine, so I decided to use up the initial Epson carts before installing the refill carts/Cone inks I bought from IJM. Finally the first slot needs replacing, so I carefully followed instructions, but forgot the size of the original Epson ink carts. The ones I bought are a “skyscraper” model? Do I have the wrong items?
