I woudn't see how a little leaked ink could possibly harm a printer.
Yes, ink will be more likely to drop out of the head with the plug in the  
cartridge opened. But it is very little ink and drops very slowly. it is  
no problem to have the head over the park station and have it go in there.  
With even only a small amount of suction (which the stock printer does  
regularly) it will be cleaned up again. Since i have disabled the suction  
pump i simply dry the park pad with a syringe.

IMO it's no problem at all and much better than removing the carts.
A CIS is very complex in comparision, and you may have much more problems  
for example if the level in the bottles is not correct.

The only issue i had is not knowing there's a plastic membrane on the  
other side of the cart also, so i punctured this with a sharp syringe  
needle (using that one instead of the blunt one that came with it). Not a  
problem any more after fixing the puncture with some sticky tape. So  
simply do not insert the needle very far, and keep it straight down, or  
use a blunt needle.


I must say after getting the right gear the refilling does not seem as  
annoying as it looked at first. I'm rather surprised actually how well the  
printer "keeps" with the vacuum pump disabled. It will still have all  
nozzles working after several days of standing there. Only once or twice i  
had to apply some vacuum with the syringe to clear a nozzle.

Does anybody know the ideal head gap for those printers? Can anybody  
measure it with the c84 "stock" configuration?
