Load staples
Load staples if the product control-panel display prompts you with a message. If the stapler runs out of
staples, jobs continue to print to the stapler/stacker, but they are not stapled.
1. On the right side of the stapler/stacker, turn the stapler unit toward the front of the product until the
unit clicks into the open position. Grasp the blue staple-cartridge handle and pull the cartridge out
of the stapler unit.
2. Insert the new staple cartridge into the stapler unit and rotate the stapler unit toward the rear of the
product until the unit snaps into place.
