I have IP3500 now, but haven't got the chance to refill, but I used to have i865 which basically use the same non-chipped cartridges BCI-6. I have printed ....God....countless of pages, like 15000 pages perhaps. This cartridge can be refilled so many times. In fact, during my 2 years of use, I only changed 2 cartridges (Red & Blue) , and that's also because they looked dirty.....NOT because it stopped working with refill.warlock110 said:the IP3500 refill doesn't look that bad, do you know how many times can you refill that canon cart that comes with the printer before you have to get new carts?
