Digital BW, The Print

I have a new 1280 printer which I outfitted with MIS VM ink cartridges 
instead of the Epson supplied cartridges. I need to do color printing 
occasionaly, and until I can get a dedicated color only printer, can I 
swap these cartridges back and forth with the Epson cartridges?. 

Do I need to store the partially emptied cartridges in a particular way 
to prevent ink from drying between changes? 

What kind of steps should I take to prevent residual inks from 
contaminating the first prints after the change. 

Also, will the swapping cause any false "cartridges empty" dialog with 
my Epson driver software?
