To install a standard paper roll, press down the Advance Manual Cutter 
(AMC) button on top of the printer.

AMC button down opens the cover for you to clean the printer 
head, replace paper, or fix a paper jam.

• 

AMC button up allows you to cut paper.

2. 

Remove the empty paper core.

Insert a new paper roll so it unrolls from the bottom easily.

and then press the AMC button again to raise it up. You can then cut the 
extra paper.

Align the battery hook on the back of the printer.
