Mark:  There is no significant vacuum once the carts are filled with 
ink.  The original vacuum is *replaced* with the ink that is sucked 
into the cart during the original fill.  The ink then is pulled into 
the cart be capilillary action and the tiny vacuum created when the 
ink is *pumped* through the printhead.

You major clog could have been caused by pulling air through the head 
when you first installed the carts prior to vacuum filling the carts 
or drying out of the head during a prolonged installation process.
