I bought a Canon Pixma MX340 printer, and I have to admit, I had a problem figuring out how to load paper so that I could print something. I couldn’t locate how it’s done in the manual, so I kind of just started sticking paper in every slot I could find like a madman. Luckily, I eventually figured out how it’s done properly.
There is a door in the back of the printer the opens up. This is the tray for loading paper for printing. You can also load glossy photo paper there too.
There is a different slot for scanning and copies. You can open up the tray on top of the scanning bed for this purpose.
