as underneath my scribble :
Interesting thaught - can you give a bit more how you did this and dont the
heads leak and run into the printer while the suction in the tank is released
during refill? or do you rely on speed! Good idea though..

I first started to screw the carts down when I was getting broken
lines and knew everything was clear. The heads were clear because I
could spray water through them with pressure using a syringe. The
tanks were clean and flowing. So I decided I had an air gap or poor
seal at the connection of the tank and head. I could manually push
them down slightly too. Anyway, fastening them down solved the print
problem instantly in my case. I have small holes drilled on the rear
of the tanks with thumb screws threaded in the holes (6-32) so the
original vent system is totally intact. Filling is fairly quick this
way. Also, I have the top of the printer hinged at the print head
resting area so I fill with the printer turned off. Because I have
such good access to the print head area, it would be immediately
evident if the head were leaking.
