That would actually be easy, while the (swedish?) method is usually  
executed with a unmodified printer and two sets of carts you could do the  
same as i did and pull all the chips of the carts, solder them together in  
parallel like they are in the printer, and swap the whole stack.

I reset the whole stack with the reset software for the PC (volkan linked  
to the page), because i don't have full chips.

I find it much more reasonable to remove the chips from the carts and have  
them at a separate location. One really doesn't want to pull the cart to  
reset the chip if it isn't needed. They should do that from the start.....
