Canon Pixma IX6850 A4 Paper Jamming

Hi all,

I own a Canon Pixma Ix6850 which I couldn't see listed as an option. I have had this printer for 2 weeks and I have been printing with 220gsm matte photo card on A5, A4 and A3.

My issue is the A4 (only) is constantly not feeding then saying jammed. Like the printer won't take the paper. I use the same spec paper for all 3 sizes and it never jams for A5 and A3. But for A4 it is every single time. I am at a complete loss on how to fix it.

I have the settings on Matte Photo Paper with the high quality setting.

Can anyone advise?
