HHmmm, that would be a last resort move John. You risk damaging the 
head beyound repair if you pressurise it and delaminate the thing. They 
are quite delicate. Also, it does not sound like the problem is with a 
clclog anyway. It sounds like an airlock or some other issue with the 
caatridge.

I have found some success in filling the cartridge until ink starts to 
come out of the exit hole and THEN draw out 1/4 to 1/2 ml of ink and 
bubbles out of the exit hole. Put the cart back in and give it a 
cleaning cycle after leaving it standing for a couple of hours.
