Electric staplers will also have a release button on the back. Hold the base steady when opening a stapler. Some models may vary, but in general, you can open a stapler by pulling it open or by pushing a back button.
If you are using an electronic stapler, the staple will shoot out immediately. If the electronic stapler does not shoot the stapler out immediately, push your papers further back, and be sure it is plugged in. You will hear electronic staplers “click” when the papers are bound.
Let the base hang as you use the stapler tray end for tacking. Do not use electronic staplers for tacking.
