Canon pixma black ink

I have a canon pixma mp560. I replaced the large black tank and now the printer does not recognize the tank. When it is snapped and lights up the other lights go out. If I unsnap it and tape it down when the light comes on but before it snaps in sometimes it will work. I have tried three new catridges and it does the same thing, Can this problem be solved? Do I need to take it to a repair shop and can they fix it?
