Pixma iX6820 won't print teal

Hello! 

I got this printer in October, have installed the most up-to-date driver and have only used this printer for black and white as well as smaller colour projects until now. I've tried printing a few different ways (directly from my illustrator file, PDF, JPG in both CMYK and RGB profiles) and it will not print teal. It's coming out as a rich cyan. There is yellow and red in this design which seem to be printing fine. I've run a colour test and it looks normal. I contacted the support chat and he had me try 20 different things and nothing worked.

Has anyone else had this issue? I've tried different paper stocks and nothing helps. 

I've tried printing it on my low quality Epson all in one and the colour looks fine but I would love my high quality printer to actually be able to be used as intended especially since I'm a freelance graphic designer and rely on this printer for mockups. 

Thank you in advance!
