Our Officejet 4500 does not recognize the color print cartridge, but the black one works fine. This happened when it was new, again only with the color one, but after taking it out and putting it back in several times, it finally worked. We have just run out of ink for the first time, bought new cartridges, and replaced them. The black ink cartridge worked fine, but it says the color one is incompatible. When we put the empty color one back in, it's happy. Yes, we've removed the paper covering the contacts. Since we initially had trouble with the original, I suspect the contacts aren't aligning correctly. Any suggestions? Thanks!
