look at your staples store, their clearance them now..
Look on FB Marketplace for Canon MB2320 or MB5020...
printhead is flooded or damaged if black is leaking
take head apart, look at TOP of head
SOME people have cut a little plastic square to DROP into the hole Under clear thin plastic, then MELTED a STRAW with lighter, dripping into the crevice
check for leaks in the plastic seal
I'm about to GLUE...
I believe there is a SLED Tool required for proper installation
what is wrong with printhead?
I've heard people TURNING their PRINTER UPSIDE DOWN to get air out??
I've not tried..
I'd go into hidden menu, Home, Back,Back,Back,Back
Look for printhead recovery
that fixed one on mine
