Terry,

I am still not sure what the ink channel concept is of the iPF models. 
As I understand it there are two connectors on the carts and it was 
suggested to me that ink is circling in part of the system but not 
totally to the head buffers. A user remarked that on a used cart there 
is ink seen at both connections which would confirm the system described 
above. Yet when I talked to a service man working on an iPF9000 (flat 
cable repair, a flaw on that machine, first symptom; LM channel starts 
printing irregular) he indicated that the extra hole was just to 
compensate air pressure when ink was drawn from the cart.

I am even more interested in the HP Z6100-6200 system. There is not the 
usual HP membrane pump on the cart outside and it has two connectors. 
Whether that suggests a circling ink system, an air pressure system or 
just an extra inlet for air, I do not know. When that cart is empty I 
will take it apart. No Z6100 here, just using the ink for mixes.
