8600 HP Al in One - Different 950/951 cartridges

[summeruptuzzy]

I bought new 950 and 951 cartridges for my printer from Best Buy.  When I installed the yellow cartridge, my printer immediately had an error.  I tried resetting and rebooting, etc... but the error remained.  I put the old yellow cartridge back in and the error was gone.  I noticed the working cartridges have a more detailed number, CN052AN.  The new one I bought was labeled CN052A.  It does not have the "N."  But, it is still called a 951.   So, are these new cartridges useless for my printer?  How do I get these new ones to work?  And, if I have to take these back, how will I know in the future whether the "N" exists on the cartridges?  The outside packaging does not include this info.  Please help me get these new cartridges to work.  Thank you!!
