Trouble with my Cartrigde or Printhead on HP 1210 all-in-one

Recently I  bought new cartridge for my HP 1210 al-in-one Printer 56, 57 Tri-color. I put the cartridge in the slots and still is blinking the light-"Check Print Cartrigde" and not printing.  I checked evrything around, even in the back door if there was a paper stuck and everything looked OK.  The cartridge is the correct one(the model), so I'm not sure what to do, please help if there is anything that I'm missing or not doing correct.

Thank you!
