Digital BW, The Print

Hi,

I will be away from home for a couple of months. I read somewhere (in
this list, I think) that epson ink contains solvents that can
prevent/minimize clogs, so I will install original epson cartridges in
my R2400. My question is: what do I do with the refillable cartridges?
Should I extract the ink from them, or just store them full? 

Thanks for sharing your knowledge and insight!
