How do I replace the paper roll in my Genius V400m?

Note: Use only 57mm x 40mm thermal printer-paper.

To open the paper compartment on your device, pull up the latch, and then pull down the compartment door.
Remove the empty paper roll from the paper compartment.
Insert the replacement paper roll with the edge of the paper at the top of the roll.
Unroll the paper until it is over the serrated edge of your device, and then close the compartment door.
