I bought a recycled cartridge for the sake of recycling - there was little or no cost saving over a new one, though it's supposedly filled with more ink and so will hopefully last longer. Unfortunately the print quality is not up to par: I'm getting a lot of bleeding and smearing, it's good enough for everyday printing like driving directions or rough drafts of the kid's essays, but when I want something of letter or resume quality I have to use a different printer. It does not register on the printer's ink level detection as the seller stated in product description.

I've been using the same printer with the same cartriges (not the same cartriges literaly, I mean, I run out and buy another... you know what I mean) for about 3 years now and never had a problem, hopefully it stays that way!

Well, I can't get too excited about a review for a ink cartridge. What I can say is that ordering through Amazon is always a safe bet at a quality price. Very happy with my ink.

I bought an MP470 printer on 9/4/08. I put in a full black ink cartridge (PG-40)and made no more than 30-35 copies on regular paper. It shows that it needs to be replaced. I called Canon and was told that the average number of pages would be 355 for one PG-40 cartridge. I thought the cartridge might be defective but the tech support person tells me that it would show an "error" on the printer if that was the case.

I will continue to use the cartridge until it totally runs out of ink but I am very unhappy with the number of pages I was able to print.

Canon has made it almost impossible to use recycled ink cartridges. They are not alone. There should be a more economical and environmentally friendly alternative available for purchasing ink - not just the limited options imposed by a monopoly held by the manufacturer. Just think if you buy a car and could then only buy gasoline from the car manufacturer!
