I have the Canon pro9000 and refill the carts with OCP inks.....works perfectly with no external tubes etc and I would argue is better value for money.....ink costs the same obviously, and a chip re-setter is needed......but no CIS unit....some of which can be quite expensive.
I have used cheapish CIS units off eBay for a 2200, R1800 and R800. I had problems but most of them were down to the printers themselves....they seemed keen to clog even with Epson carts. I strongly suspect the more modern printers will have fewer problems.....
My dilemma at the moment is what to do about my R2880...OCP don't make ink for this printer but I can find re-fillable carts and other pigment inks. The main problem is (as I see it) the carts use the same chips as CIS units....in other words, when the chips think the cart is nearly used up they reset to full...which means the printer cannot detect when a cart is empty and will try and continue printing.....not good apparently!
That is the situation I am in with my old R800...I am constantly taking the carts out and topping them up..which works...but is one more thing to have to think about!
