My HP Deskjet Ink advantage 2545 was working properly for many years. Just now when my black cartridge got exhausted, I run printer for sometime using only colour cartridge for a month. Later when I put New Black cartridge; error 'Incompatible cartridge - Black' is displayed. I have followed all tips to clean cartridge, carriage and steps to update firmware, printer reset etc. It didn't work. I changed the Black cartridge and got new cartrdige. Same error. Both cartridges were purchased from authentic HP shops. Its HP 678 cartridge which is recommended in India.
