MY HP PHOTOSMART C4480 ALL-IN-ONE PRINTER KEEPS BLINKING A GREEN LIGHT AND SAYS  INCOMPATIBLE PRINT CARTRIDGE(s). I have changed the cartridge (the black one) and it still keeps saying this.

Thank you for posting on HP Support Community.

 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Reset the printer to recover from printer failures.

  1. With the printer turned on, disconnect the power cord from the printer.

  2. Unplug the power cord from the power source.

  3. Wait 60 seconds.

  4. Reconnect the power cord to a wall outlet and to the printer.

Hope this helps! Keep me posted for further assistance.
