The staple cartridge must be empty.

Reverse the cartridge upside down.

Then lift up the clear plastic bottom cover.  It will tilt with the bottom metal plate.

Insert the refill pack with the arrow pointing towards the staple cartridge.  The arrow must also be away from the orange handle of the staple cartridge.

Push the refill down until it clicks.

Remove the paper strip by pulling the large white pull tab. The staple strips are now free to move out of the staple cartridge.

Then close the clear plastic bottom cover until it snaps into place.
