R3000 Refillable Cartridges or CIS
Used a CIS with my r2880 and had nothing but problems with it. But that was with a system where the ink supply travels along with the print head, so the tubes were always moving with the print head. When I got the r3000 I changed to refillable cartridges from Cone Inks. They have performed flawlessly, and the ink match is perfect or better. It's probably true that a CIS would work OK with a printer like the r3000 where the ink supply is fixed. But I'm not messing with success.
Only my opinion. It's worth what you paid for it. Your mileage may vary! ;-} www.dougwigton.com/
