"Could be a cart thing, maybe mine are
different?".

They must be. Are yours the auto re-set type?
 
The ones I'm refering to are here and they have the same part number as 
the MIS ARC carts:

T079420/Detail.bok

Anyhow, the carts work fine. Just don't overfill the carts when you top 
them off or you may get leakage from the valve. If you fill til  ink is 
level with the fill hole, that's too much ink. 

After topping off a second time today, no leakage. I didn't fill the 
carts as full the second time around.

Get set-up so far and highly recommended to anyone who likes BO 
printing. :~)
