I ended up with the R1800, so your experience should be directly applicable...lucky that.
I'm really just interested in general use information. I've had so many problems (with other printers and products) with printer alignment/head cleaning/bad carts/failed refills, etc...that I begin to question my competency when it comes to aftermarket inks and carts.
Perhaps I'm only smart enough to use the manufacturer's inks...
Anyway, how easy/reliable do you find the system to be?
Do you buy their carts, refill, or use a CIS?
How many prints do you get before you have to address some problem or other?
Thanks,
