My printer prints ok with black ink but when printing colour, it prints the wrong colour and very faint. I am running windows xp and i am not receiving any error messages.Any chance the colour cartridge is out of ink, Michelle?checked that. ink levels are showing half full.Have you tried cleaning the nozzles and realigning? Use your Lexmark utilities for doing this.Tried all that.    Did you FILL the carts yourself/or are these a re-fill carts !! did you RUN the the test page!Typical inkjet cartridge.  Not designed to last very long, whether you use it or not.Change the settings to auto! if unsure post back!not sure.Did a test page and the black bit came out ok but the coloured parts were all wrong colour, faded and with horizontal lines.still not sure how to change settings to auto.I had the same problem with my last printer, a dinky Canon BJC series in the same category as your Lexmark. I never did solve it, because on these printers there's nothing to fix; all the parts are non-replaceable. This is a bad printer RIGHT out of the box, according to the reviews, and you may have a problem with no solution. This is a prime EXAMPLE where cheaper ends up being more EXPENSIVE, because now you may well have to replace this unit.1)      Open the Lexmark Printer Properties.
2)      Click the Document/Quality Tab.
3)      Under Document Type, click auto Only.
