PIXMA PRO-100 stopped recognizing light grey ink tank

My Pro -100 all of a sudden stopped recognizing light grey. They worked fine and I never haven't a problem before. Cartridges are Canon. Holding the stop button, cycling the power, reseating cartridges did not work. Any suggestions?

Is it with more than one LGY cartridge or just a particular one?
