How do I insert the paper roll into the PAX A920?

First open the paper roll compartment on the back of the machine by pulling the tab on the top. Place the paper roll in the tray so that the front of the paper comes out the bottom of the roll and leave about 1 cm overhang, then close the tray. The paper roll dimensions should be 57mm width with a maximum diameter of 40mm. (Page 3)
