It came with a full set and I bought another full set at the time of purchase. It uses a black cartridge and a three in one colour cartridge, so that 2 carts in all.
However my printer doesn't seem to be using it's black ink cartridge at all. Hello, I've recently bought a canon pixma ip2600, I've had it about 2 weeks, now this isn't my first canon printer or printer in general and I've never come across a problem I couldn't fix myself yet.
