quote from review article in first link- (what ive been preachin for years)
"So, my advice for the time being-- get an OLDER Canon Printer that uses the reliable dependable 6BCI ink carts, like a ip3000, ip4000, ip5000, or ip6000. Not only can you get first class aftermarket ink carts for these from companies like Inkgrabber (above link), but you can refill with the highest quality bulk ink if necessary Till then, AVOID any printer using microchips on their ink carts-- its a rip off, and it significantly adds problems to your printing experience unnecessarily- except to increase the profit to these huge corporations who are already making billions of dollars selling their products."
