So that the Community can help you better, we need to know exactly which Canon printer model you're using. The PIXMA TS6300 series is a family of printers that's available worldwide with different model numbers corresponding to the part of the world each one is intended for, such as the North American model PIXMA TS6320 and the European model PIXMA TS6350. It would help to know which specific one you've got. That, and any other details you'd like to give will help the Community better understand your issue!
