For the first time ever, after replacing three genuine HP 902 color cartridges with three new genuine 902 color cartridges, I'm getting this Defective Cartridge message on my printer.  "Printing is unavailable because the indicated cartridges are defective."  It gives the letter C which I interpret as Cyan.  I've never received error messages like this before, and have always used genuine HP cartridges.  I don't have any more replacement color cartridges in my home office, and they are sold out practically everywhere.  Any suggestions?

Additional Info:  After receiving the error message and finding myself unable to print at all, I removed the "defective" New Cyan cartridge, and put the old one with very low ink back in the unit. At least that allows me to print temporarily in black and white/grayscale.  Frustrating.
