Digital BW, The Print

Hi everyone - 

I just purchased the MIS ink set for a C-86.  I'm having an identical 
problem with the ink cartridge leaking.  The refills were bought from 
Hong Kong - spongeless carts for a C-86.  I first thought this was the 
fault of the carts, but as others are having the same problem, I wonder 
if this might be a bad batch of ink from MIS.  

When I swap out the cartirge with an Epson version, everything works 
fine.
