So there must be some setting I've over looked, or some stupid mistake I've made. I've been through all the settings of all the programs I've used, looked in the control panel, tried everything I know. I've carried on printing and the second colour cartridge ran out, but the first black cartridge is still showing as completely full in the ink monitor window (that's the one the computer shows you on screen).Ībout half of the stuff I've prinited has been black and white photographs, so the natural assumption is that the printer has been using the colour cartridge to do all the black printing. I printed a bunch of stuff and the colour ink ran out, which I replaced with the other cartridge I bought, but the black ink in the printer ink monitor window was still reading as full. I never expect the cartridges that come with a printer to last very long at all. 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.
