Canon G600 ink splotch on trailing corner

[Burdonmark]

Hi, when printing on thicker stock only, I'm getting an ink splotch right on the trailing corner of the card stock every time.

I've set the printer to the correct paper type and tried all the cleaning routines but it's still doing it. Any help?

Greetings,

Is this happening on every printed page?

Are you certain the stock you are using is supported?

I would also inspect the inside of the printer for any spilled inks, and clean the bottom plate:
