Digital BW, The Print

Hi,

just like to share with you very nice experience. I have order 6 days 
ago UT inks in bottles and all necessary stuff for refilling 
cartridges for epson 890. 
It tooks only 6 days to deliver to Netherlands! Incredible!

Now one simple qustion:
What should I look for when I change epson original cartridges to 
these new MIS UT refilled cartridges?

I plan to fill one set today. Let it sit over night than put it in 
printer, leave it there for half a day and than print purge patter 
and  start printing.

Did I miss something?
Thanks for your sugesstions.
