Digital BW, The Print

I know this has been asked before but I can't pull it up in the archives. 
Have just refilled and installed (with appropriate clicks and green light on 
chip resetter) all inks on my Epson C82.  Printer recognizes the black and 
cyan but not the magenta and yellow.  Prior to this I have gotten a message 
saying these were not Epson Carts and allowing me to click OK to continue. 
Not so this time, I get a "Printer does not recognize installed cartridges" 
everytime, can't do a nozzle check, head cleaning much less print.  Any and 
all help appreciated.  Thanks.
