This part typically isn't sold alone , Canon includes this with the control panel.Best thing to do is to check a Canon parts dealer or repair service center using your model/serial #, and they can tell you the part number and stock.
Seems to be a driver/memory problem with large prints. Update driver, try a draft print and ensure adequate spool space. Try an altenative cable/port.Thankyou
It sounds like black nozzle on the Canon Pixma G3270 is clogged or not primed. It might be a defect if cleaning it didn't help it. Since it's still new, you should call Canon.
