Canon pixma pro 100 ( Yellow does not work)

What I am offering: 1. The printer 2. Heavy cardstock paper 3. The installed ink I was scammed earlier this month into buying this printer. As the title states, the printer DOES NOT print yellow. After many attempts to clean the printer head, it still does not work. As far as I can tell everything else does work though. Most likely just needs a new printer head but the event I needed it for as already passed so I don’t need this. I have replaced all the inks with the ink you see in the picture. And those prints are the quality/ color of this printer with its current ink supply level as well.
