Bought 4 XL (including black) replacement cartridges and replaced cartridges in December 2011 after printing Christmas cards. Have not used a lot, but have used the color printer here and there for both photos and documents since replacing the cartridges. I have never had this happen but all of a sudden after printing one photo, the cyan cartidge became "damaged" according to the error message. I can tell it still has ink in it. I removed the cyan cartridge and re-installed it, and still got the error message. I removed the cartridge again, carefully swabbed the contacts on the cartridge holder with a qtip dipped in rubbing alcohol, let it dry, and put the cartidge back in, and still get the error message. I wasted a lot ot time on a nice Sunday afternoon trying to deal with this. I will order a regular size cyan and maybe from now on just order regular size for all the colors and see if they work better than the XL size.
