The Swingline 67 electric stapler is easy to load and holds a full strip of standard sized staples. The Swingline 67 can staple a stack of up to 25 sheets of regular width printer paper. It also includes an adjustable gauge to adapt if you need to staple different types of paper, like card stock or construction paper. The stapler features a front pop-out loading dock for adding new staples, but it is not immediately clear how to add staples when the stapler is out.
Turn the side knob to the left. The knob is located at the bottom of the right side of the stapler. Turning the knob will release the front loading carrier. Click on the link under "Resources" at the bottom of this page for a photo of the side knob and the released front loader.
Pull the front loader out so you have enough room to load the staples. Put a strip of standard Swingline 1/4-inch staples into the front loader.
Push the front loader back into the stapler. The side knob will return to its original position when the front loader is secured.
