The cross shaped piece isn't the backflow valve but seats 
the spring so shouldn't be removed. The backflow valve is 
behind the cross shaped piece. At least that's how it is in 
the 10000 and 9800 carts. There's a file with photos + text 
on the Epson wide format list that shows how to do it on 
10000 carts and the 9800 are the same but just smaller and I 
guess the 3800 are even more reduced.
