After putting the Smart Ink black replacement cartridge in

My HP Office Jet 6600 was low on black ink. After putting the Smart Ink black replacement cartridge in, printer refused to print. Black ink is shown as full on the display, but printer won't print. Put HP cartridge back in and printed the status report just fine. I will continue to try, but I'm not optimistic. Look forward to my request for a refund.
