Digital BW, The Print

Ok I see to be going one step forwards and one step backwards here.

I think I have cleared the issue with the ink line - hopefully.

I am now trying to reconnect the white "t joint" where the line  
connects to the top of the head.  However, when I slide the line on to  
the t-joint and retighten the sleeve, it no longer grips the line....
