My printer worked good until I replaced the cartridges with a generic name. Then it just wouldn't print. I bought the Canon cartridges and everything worked fine. Last night while I was printing I got the message that "Printer Head not install"
Does this mean a repair shop or is there something I can do to fix it?

First try the maintenance instructions before contacting the repair shop
