Digital BW, The Print

Has any brave soul tried refilling the spongeless carts on an 1160, 
1280 or 2200 without removing them from the printer?

I've got some auto-reset chips for the 1280 and 2200, and it sure
would be nice to just top off the various positions with a syringe as 
needed without having to pull the carts and re-prime them. Yep, I'm 
definitely being lazy ;>)

Just a thought, but I'd be interested to hear if anyone has done it...

Cheers!
